Summary: Two experiments from the Fermilab reported anomalies for muon g-2 and W-boson mass that may indicate new physics at the low energy scale. This study examines the possibility of a common origin of these anomalies in the Next-to-Minimal Supersymmetric Standard Model. Results show that lighter electroweakinos and sleptons can contribute to muon g-2 and W-boson mass, while the corresponding neutralino dark matter mass is in the 180-280 GeV range.

Summary: Motivated by the anomaly in the W boson mass observed by the CDF collaboration, the authors propose a singlet-doublet Majorana fermion dark matter model. They find that the required correction to the W boson mass can be explained by radiative corrections induced by the singlet-doublet fermions. It is shown that two generations of singlet-doublet fermions can account for the W boson mass anomaly and also be consistent with dark matter phenomenology.

Summary: In the Type-II seesaw model, the introduction of an electroweak triplet scalar field Delta is essential for the generation of small neutrino masses. The non-zero vacuum expectation value of Delta affects the W mass, but recent data suggest that this effect can be neglected.

Summary: This study examines the anomalies of W-mass and muon g - 2 reported by CDF II and FNAL using a model with mu-tau lepton flavor violation interactions. The results show that there are parameter spaces where the CDF W-mass, FNAL muon g - 2, and lepton universality in tau decays can be simultaneously satisfied, but with strict constraints on the mass splittings among extra Higgs bosons.

Summary: The new measurements of the W-boson mass and muon g-2 show significant deviations from the standard model predictions, suggesting the presence of new physics. This study explores the implications of these measurements on low energy supersymmetry and finds that the minimal supersymmetric standard model can explain both measurements within the allowed parameter space, considering theoretical uncertainties. The favored parameter space is characterized by a compressed spectrum between bino, wino, and stau, with the stop around 1 TeV, which may be probed in future LHC searches.

Summary: The W mass determination at the Tevatron CDF experiment shows a deviation from the SM expectation, and possible interpretations and collider implications are discussed in this paper. It is found that single gauge boson extensions face strong LHC direct search constraints, but the deviation can be explained by mixing extra vector fermions (leptons) with the SM fermions (leptons).

Summary: The recently reported measurement of the W-boson mass is heavier than the Standard Model prediction. This study investigates the anomaly using the scale invariant Two-Higgs-Doublet-Model (SI-2HDM) with a Z2 symmetry. The results show that the SI-2HDM model can accommodate the W-boson mass anomaly and there are viable regions in the mass spectrum that evade experimental bounds.

Summary: We propose an explanation for the new W mass measurement reported by the CDF collaboration, which deviates from the standard model expectation by about 7 standard deviations. By introducing a new neutral gauge boson in the Stueckelberg extended standard model, we alleviate the tensions in the electroweak sector caused by the new W mass measurement. We find that the extension increases the W boson mass when the mass of the new gauge boson is larger than that of the Z boson. Additionally, we show that there exists parameter space in the extended model consistent with the CDF mass anomaly as well as various observables at the Z pole and ATLAS dilepton limits. The Stueckelberg Z'(St) boson, which resolves the CDF W mass anomaly, can be searched for in future LHC experiments.

Summary: This article discusses the prediction of the W boson mass in a simple extension of the Standard Model, specifically with a real scalar triplet. The model can naturally accommodate the reported shift in the W mass without modifying the Standard Model value for the Z mass. The article also explores the implications and properties of the new Higgs bosons, including the predicted partial decay widths of the new charged Higgs and the dominant decay of the neutral Higgs into a pair of W gauge bosons.

Summary: We discuss the implications of the CDF collaboration's high-precision measurement of the W boson mass on models with a non-standard Higgs, showing that an enhancement of more than 5% in the non-standard Higgs coupling to gauge bosons is required. This can be naturally explained in dynamical models such as the dilaton Higgs, Technicolor, and glueball Higgs. The needed composite scale between 2 and 3 TeV can also account for the muon g-2 anomaly and potential violations of lepton flavour universality.

Summary: The study globally fits electroweak data and finds that new physics corrections can explain the anomaly in the W boson mass. Tree-level contributions from multi-TeV new physics can fit the anomaly compatibly with collider bounds, while loop-level contributions must be around the weak scale to fit the anomaly.

Summary: This work revisits the existence of a strong first order electroweak phase transition (SFOEWPT) and recent m(W) precision measurement in the Type-I and Type-II 2HDMs. The study finds that both Type-I and Type-II 2HDM can explain these precision measurements under current constraints, and heavy Higgs mass splitting in 2HDM plays a crucial role. The allowed parameters for Type-I and Type-II 2HDM are Delta m(A/C) is an element of (-400, 400) GeV, tan beta is an element of (1, 50), and Delta m(A/C) is an element of (-200, 300) GeV, tan beta is an element of (1, 10) respectively.

Summary: This article presents an updated calculation of the W boson pole mass in models beyond the standard model using FlexibleSUSY. The calculation exhibits a decoupling behavior and provides precise predictions for the W pole mass up to large new physics scales. The calculation is applied to various standard model extensions, including MRSSM, which demonstrates its compatibility with large corrections to fit the recent 2022 CDF measurement of the W boson mass.

Summary: This paper investigates the discrepancy between the direct measurement and the Standard Model prediction of the W-boson mass reported by the CDF Collaboration at the Tevatron. The authors explore the potential origin of this discrepancy in physics beyond the Standard Model and demonstrate that it can be attributed to a specific operator in the Standard Model effective field theory. They suggest that the scale of new physics favored by the data should be multiple TeV for tree-level effects and sub-TeV for loop-level effects. The authors also propose a simple example to explain this phenomenon and discuss further testing of the relevant physics theory at future colliders.

Summary: Recently, the CDF Collaboration reported an updated result on the measurement of the W-boson mass, which showed a deviation of 7 sigma from the standard model prediction. This discrepancy may indicate the presence of new contributions to the Fermi coupling constant. Simple extensions of the standard model were studied, and it was found that the tension implies the existence of new physics at multi-TeV scales if the new coupling to the electron and/or muon is of order unity.

Summary: This study enumerates various effective couplings that contribute to the mixings between an exotic vector boson Z' and the neutral electroweak vector bosons. Perturbative evaluation of the miscellaneous mixing patterns is performed. The effective oblique parameters S', T', and U' are calculated and compared with the results of electroweak precision tests. By including the contributions of the non-negligible U' parameter from the epsilon B;W parameters and using other parameters to cancel the negative T', the recent CDF W-mass anomaly can be explained.

Summary: Right-handed neutrinos can resolve the tension between the latest CDF II measurement of MW and the standard model (SM). The explanation alters the extraction of GF from muon decay and increases the prediction for MW, in line with the CDF II result. However, it worsens the Cabibbo anomaly unless it is not generated by right-handed neutrinos.

Summary: This article presents the implications of the recent measurement of W boson at CDF II on the two-Higgs-doublet model (2HDM). Theoretical and experimental constraints are imposed, and the determined S and T parameters are investigated. The article explores two scenarios based on the observed Higgs boson at the LHC for 2HDM type I and II. The parameter space is constrained and compared with the PDG average of m(w), and the consequences of electroweak precision observables within the predictions of the 2HDM are discussed, as well as the expected reduction in parameter space from future measurements at the Future Circular Lepton Collider.

Summary: The new measurement of W-boson mass by the CDF collaboration shows a significant discrepancy with the predictions of the Standard Model. If confirmed by other experiments, this discrepancy strongly suggests the existence of new physics beyond the Standard Model. In this study, seven vectorlike quark extensions of the Standard Model are investigated, and it is found that three of them can explain the anomaly in a wide parameter space.

Summary: This study investigates the effects of vectorlike leptons with a U(1)' gauge symmetry on the W-boson mass, and provides explanations for recent anomalies in the muon anomalous magnetic moment and the semileptonic decays of B mesons. The findings suggest that the precise measurement of the W-boson mass at CDF can be explained if charged or neutral vectorlike leptons have a mass smaller than a specific value. These light vectorlike leptons may not be excluded by collider experiments if they decay into a physical mode of the U(1)'-breaking scalar field.

Summary: We propose a new model for lepton flavor and dark matter based on SU(2)(D) gauge symmetry and vectorlike leptons. We introduce a dark SU(2)(D) Higgs doublet and a Higgs bidoublet for mass mixing between the vectorlike lepton and the lepton. As a result, the seesaw lepton masses are generated and there are significant one-loop contributions to the muon g - 2. The tree-level mass mixing between the Z boson and the isospin-neutral gauge boson of SU(2)(D) explains the shift in the W boson mass. Additionally, the isospin charged gauge boson of SU(2)(D) becomes a plausible candidate for dark matter, with a small mass splitting tied to the modified W boson mass.

Summary: This paper presents a simple extension of the Standard Model that involves a vector-like lepton and a local U(1)' symmetry to explain recent experimental anomalies. By spontaneously breaking the U(1)' symmetry with the VEVs of the dark Higgs scalar and the second Higgs doublet, mixing between the muon and the vector-like lepton occurs, resulting in corrections to the muon g - 2 and the W boson mass.

Summary: Motivated by the deviation of the W boson mass reported by the CDF collaboration, we study a lepton portal dark matter model. In this model, vectorlike leptons and a scalar dark matter exclusively couple to the extra leptons and muon, causing one-loop corrections that can shift the W boson mass. Additionally, this setup can explain the discrepancy in the muon anomalous magnetic moment and the DM density if the vectorlike lepton is lighter than 200 GeV and nearly degenerate with the DM particle. Furthermore, the constraints from collider experiments on such a light extra lepton can be evaded due to the existence of the DM particle.

Summary: The discrepancies in the anomalous magnetic dipole moments of the muon and electron are addressed by extending the inert two Higgs Doublet Model with a SM gauge singlet complex scalar field and singlet Vector-like Lepton field. The allowed parameter space is constrained by Higgs decays to gauge Bosons at LHC, LEP II data, and electro-weak precision measurements, explaining the muon and electron MDM's within a common parameter space for different sets of allowed couplings and masses of the model particles.

Summary: A new simplified fast detector simulator has been introduced in the MadAnalysis 5 platform. By comparing predictions with Delphes 3 software, the results generally agree to a level of about 10% or better, with the largest differences stemming from different strategies used to model specific detector effects. MadAnalysis 5 now offers a user-friendly way to include detector effects when analyzing collider events.

Summary: The long-standing tension between experiment and Standard-Model prediction in the anomalous magnetic moment of the muon points to the existence of underlying physics beyond the SM, which may be related to heavy new particles with chiral enhancement and correlations with observables sensitive to EW symmetry breaking can be expected. These scenarios can be classified according to the SU(2)(L) representations and the hypercharges of the new particles.

Summary: The study focuses on the extended 2Higgs doublet model where the Standard Model Yukawa interactions are forbidden due to a global U(1)' symmetry. By considering various nonstandard contributions to the electron and muon anomalous magnetic moments within the model, it is shown that nonstandard contributions are possible within the experimental constraints. Benchmark points for both muon and electron anomalies are presented, along with numerical scans indicating the mass regions of the Higgs scalars in this scenario.
