Models of the muonium to antimuonium transition

Takeshi Fukuyama et al.

Summary: This paper discusses the models that can be tested in the next generation of the muonium-to-antimuonium transition search experiments, including heavy Majorana neutrino models, type-II seesaw models, left-right models, and models for radiative neutrino masses. These models can induce a sizable transition probability and can be tested in upcoming experiments.

Low-energy phenomenology of scalar leptoquarks at one-loop accuracy

Valerio Gherardi et al.

Summary: In this study, we conducted a comprehensive examination of the low-energy phenomenology of S-1 and S-3 leptoquarks, focusing on their impact on deviations observed in B-meson decays and the muon magnetic dipole moment. By calculating leptoquark contributions to observables at one-loop accuracy using an effective field theory approach, we presented various scenarios and discussed the preferred parameter space and most relevant observables in each case.

Search for Lepton-Flavor Violation in Z-Boson Decays with τ Leptons with the ATLAS Detector

G. Aad et al.

Summary: This study presents a search for lepton-flavor-violating Z -> eτ and Z -> μτ decays using data recorded by the ATLAS detector at the LHC. By combining data from Run 2 and Run 1, the addition of leptonically decaying τ leptons significantly improves sensitivity for Z -> l τ decays. The combination of previously published analyses sets the strongest constraints to date on the branching fractions B(Z -> eτ) and B(Z -> μτ).

Universal scalar leptoquark action for matching

Athanasios Dedes et al.

Summary: This study presents a universal effective action for one-loop matching of all scalar leptoquarks, using UOLEA and covariant diagrams to evaluate Wilson coefficients directly. The technical approach includes using the newly developed method of evaluating supertraces to further validate results. The model with two scalar leptoquark fields is used as an application, performing a full matching onto SMEFT and calculating various observables, highlighting its phenomenological interest and providing an EFT benchmark for future automation.

Summary: This paper reports world averages of measurements of b-hadron, c-hadron, and tau-lepton properties obtained by the Heavy Flavour Averaging Group using results available through September 2018. Adjustments are made to common input parameters used in various analyses to common values, taking known correlations into account. The averages include branching fractions, lifetimes, neutral meson mixing parameters, CP violation parameters, parameters of semileptonic decays, and Cabibbo-Kobayashi-Maskawa matrix elements.

Leading hadronic contribution to the muon magnetic moment from lattice QCD

Sz. Borsanyi et al.

Summary: The standard model of particle physics describes the majority of experiments and observations involving elementary particles, with a long-standing discrepancy concerning the anomalous magnetic moment of the muon. Ongoing experiments aim to reduce measurement errors, theoretically attributed to the leading-order hadronic vacuum polarization contribution, to distinguish between experimental measurements and predictions. The developed methods using ab initio quantum chromodynamics and quantum electrodynamics simulations favor experimentally measured values over those obtained using dispersion methods, with potential for increased precision as computer technology advances.

Measurement of the Positive Muon Anomalous Magnetic Moment to 0.46 ppm

B. Abi et al.

Summary: The experiment presented the first results of the Fermilab National Accelerator Laboratory (FNAL) Muon g - 2 Experiment for the positive muon magnetic anomaly a(mu) (g(mu) - 2)/2, which determined the anomaly from precision measurements of two angular frequencies. The result showed a deviation of 3.3 standard deviations from the standard model prediction, in agreement with previous measurements, increasing the tension between experiment and theory.

The singly-charged scalar singlet as the origin of neutrino masses

Tobias Felkl et al.

Summary: We investigate the generation of neutrino masses using a singly-charged scalar singlet and identify two distinct structures for the neutrino mass matrix under general assumptions. This leads to a constraint on the antisymmetric Yukawa coupling of the scalar singlet, excluding large hierarchies among the Yukawa couplings. Our study explores the implications for various aspects of lepton phenomenology and discusses the parameter space relevant to addressing the Cabibbo Angle Anomaly.

Radiative neutrino masses, lepton flavor mixing and muon g - 2 in a leptoquark model

Di Zhang

Summary: The proposed leptoquark model uses two scalar leptoquarks to explain neutrino masses, lepton flavor mixing, and the muon g - 2 anomaly while satisfying constraints from the radiative decays of charged leptons. The neutrino mass matrix possesses an approximate mu-tau reflection symmetry, with (M-nu)(ee) = 0 only in favor of the normal neutrino mass ordering, and the model successfully explains the muon g - 2 anomaly and current experimental neutrino oscillation data.

Effective field theory interpretation of lepton magnetic and electric dipole moments

Jason Aebischer et al.

Summary: In this study, a model-independent analysis of the magnetic and electric dipole moments of the muon and electron is performed, with expressions for the dipole moments in terms of operator coefficients of the low-energy effective field theory (LEFT) and the Standard Model effective field theory (SMEFT) provided. It is found that semileptonic four-fermion operators involving light quarks contribute significantly to the dipole moments.

Complete one-loop matching of the type-I seesaw model onto the Standard Model effective field theory

Di Zhang et al.

Summary: In this paper, the complete one-loop matching of the Type-I seesaw model onto the Standard Model Effective Field Theory (SMEFT) is accomplished, resulting in 31 dimension-six operators in the Warsaw basis of the SMEFT. The Wilson coefficients of these operators are computed up to O(M-2), where M is the mass scale of heavy Majorana neutrinos. The effects of heavy Majorana neutrinos on low-energy phenomenology are explored through this one-loop matching, along with discussions on threshold corrections in the Standard Model and the coefficient of the dimension-five operator.

Single leptoquark solutions to the B-physics anomalies

Summary: Through the introduction of a single leptoquark state and combination with the most recent low energy flavor physics constraints, we find that only the vector leptoquark U1 can provide a viable solution to explain B-anomalies and interestingly predicts a lower bound for lepton flavor violating b -> s mu(+/-)tau(+/-) decay modes.

Search for lepton-flavor violating decays of the Higgs boson in the μτ and eτ final states in proton-proton collisions at √s=13 TeV

A. M. Sirunyan et al.

Summary: A search was conducted for lepton-flavor violating decays of the Higgs boson to mu t and e t using a dataset corresponding to an integrated luminosity of 137 fb(-1) collected at the LHC. No significant excess was found, and upper limits on lepton-flavor violating branching fractions of the Higgs boson were determined. The observed upper limits at 95% confidence level for B(H -> mu t) and B(H -> e tau) are < 0.15% and < 0.22%, respectively.
