Neutral-current electroweak physics and SMEFT studies at the EIC

Radja Boughezal et al.

Summary: This study investigates the potential for precision electroweak measurements and beyond-the-Standard Model searches using cross-section asymmetries in neutral-current deep inelastic scattering at the electronion collider (EIC). The analysis includes a comprehensive consideration of systematic errors from both theory and experiment, and explores the potential of proton and deuteron beams at various energies and luminosities. Additionally, the study examines the impact of a possible future positron beam and a tenfold luminosity upgrade of the EIC beyond its initial decade of running. The findings suggest that the EIC can probe beyond-the-Standard Model operators at scales competitive with, and in some cases exceeding, LHC Drell-Yan bounds while avoiding degeneracies between Wilson coefficients.

Shift-type SMEFT effects in dileptons at the LHC

Alyssa Horne et al.

Summary: The study focuses on constraints on Wilson coefficients in the Standard Model Effective Field Theory from dilepton production, incorporating theory error estimates from higher EFT orders. Constraints on four-fermion operator contributions and shifts are found to be robust, and a new constraint on shifts is derived, comparable in strength to LEP data. The study provides new constraints linearly independent from those at the LHC and rotated in Wilson coefficient space relative to LEP bounds.

On the W&Y interpretation of high-energy Drell-Yan measurements

Riccardo Torre et al.

Summary: This paper provides theoretical predictions of high-energy neutral and charged Drell-Yan differential cross-section measurements, including new physics effects at the Next-to-Leading order in QCD. The predictions are obtained from SM Monte Carlo simulations through analytic reweighting, enabling the exploration of all relevant interactions. Projections for the sensitivity of LHC and HL-LHC measurements are presented, along with quantification of the impact of several sources of uncertainties.

Combined SMEFT interpretation of Higgs, diboson, and top quark data from the LHC

Jacob J. Ethier et al.

Summary: In this study, a global interpretation of Higgs, diboson, and top quark measurements at the LHC was presented within the framework of the Standard Model Effective Field Theory (SMEFT) at dimension six. By constraining 36 independent directions in the parameter space, and incorporating both linear and quadratic corrections, the study demonstrated the importance of including NLO QCD and O (Lambda(-4)) effects for accurately mapping the posterior distributions associated with the fitted Wilson coefficients. The results highlight the interplay and complementarity between top quark, Higgs, and diboson measurements, and pave the way for more global SMEFT interpretations extended to other high-p(T) processes and low-energy observables.

Top, Higgs, diboson and electroweak fit to the Standard Model effective field theory

John Ellis et al.

Summary: The search for effective field theory deformations of the Standard Model is conducted through a global approach in the framework of the Standard Model Effective Field Theory. The analysis includes constraints on the coefficients of SMEFT operators and explores specific ultra-violet completions of the Standard Model, but does not find significant evidence for physics beyond the Standard Model.

STrEAMlining EFT Matching

Timothy Cohen et al.

Summary: This paper presents STrEAM, a Mathematica package that calculates all functional supertraces when matching a generic UV model onto a relativistic Effective Field Theory. The package implements the covariant derivative expansion to automate the most tedious step of the streamlined functional matching prescription.

SMEFT analysis of vector boson scattering and diboson data from the LHC Run II

Jacob J. Ethier et al.

Summary: In this study, a systematic interpretation of vector boson scattering (VBS) and diboson measurements from the LHC was presented within the framework of the dimension-six standard model effective field theory (SMEFT). The VBS measurements were found to provide complementary information on several relevant operators for the description of the electroweak sector compared to the diboson measurements. Additionally, the ultimate EFT reach of VBS measurements was quantified through dedicated projections for the high luminosity LHC, motivating the integration of VBS processes in future global SMEFT interpretations of particle physics data.

High-energy EFT probes with fully differential Drell-Yan measurements

Giuliano Panico et al.

Summary: The study investigates the potential of fully-differential measurements of high-energy dilepton cross-sections at the LHC to probe heavy new physics encapsulated in dimension-6 interaction operators. Results show a considerable sensitivity improvement relative to single-differential measurements due to the possibility of probing more directions in the seven-dimensional parameter space at the interference level. The reduction of parton distribution function uncertainties in the fully-differential fit is also found to play a significant role.

Dilepton production in the SMEFT at O(1/Λ4)

Radja Boughezal et al.

Summary: This study examines the inclusion of O(1/Lambda(4)) effects in fits to current LHC Drell-Yan data within the Standard Model effective field theory. The analysis finds that including dimension-6 squared terms and certain dimension-8 operators significantly impacts the data fits, and neglecting them leads to large errors in constraining dimension-6 operators. Additionally, specific combinations of dimension-8 four-fermion operators at the TeV level can already be probed by LHC results and including them changes the limits found for dimension-6 operators.

Complete set of dimension-eight operators in the standard model effective field theory

Hao-Lin Li et al.

Summary: Utilizing group theoretic techniques, we have systematically and automatically provided a complete list of the dimension-eight operator basis in the standard model effective field theory, adopting a new form of operators based on the irreducible representations of the Lorentz group and identifying Lorentz structures as states in an SU(N) group. By ensuring the independence and permutation symmetries of the operators, our approach facilitates the handling of complexity arising from repeated fields. The explicit form of independent flavor-specified operators has been presented for the first time, and our algorithm can be easily applied to higher-dimensional standard model effective field theory and other effective field theories, making these studies more accessible.

Disentangling Standard Model EFT operators with future low-energy parity-violating electron scattering experiments

Radja Boughezal et al.

Summary: This study demonstrates the potential of future parity-violating electron scattering (PVES) data to probe the parameter space of the Standard Model effective field theory, particularly in the dimension-six and dimension-eight operator spaces. PVES data can complement the bounds set by the Large Hadron Collider data in the dimension-six operator space and probe different combinations of operators. Additionally, the lower characteristic energy of the planned SoLID and P2 experiments can help disentangle effects of dimension-six and dimension-eight operators that are difficult to resolve with LHC Drell-Yan data alone.

Four-lepton Z boson decay constraints on the standard model EFT

Radja Boughezal et al.

Summary: This study discusses the importance of Z boson's four-lepton decays in probing unconstrained flat directions in the SMEFT parameter space, and how constraints on four-lepton operators can be derived from these decays using LHC data and future high-luminosity data. It also comments on the possibility of using rare Z-decays to tau-leptons to further probe untested directions in the SMEFT parameter space.
