    The electroweak effective field theory from on-shell amplitudes by Gauthier Durieux, Teppei Kitahara, Yael Shadmi, Yaniv Weiss

    Published 2020-01-01
    “…We supplement our bottom-up derivations with a matching of three- and fourpoint amplitude coefficients onto the standard-model effective field theory (SMEFT) in the broken electroweak phase. This establishes the correspondence with the usual Lagrangian approach and paves the way for SMEFT computations in the on-shell formalism.…”

    Precision tests of third-generation four-quark operators: one- and two-loop matching by Ulrich Haisch, Luc Schnell

    Published 2025-02-01
    “…Abstract We calculate the one- and two-loop matching corrections in the Standard Model effective field theory (SMEFT) that impact electroweak precision measurements and flavour physics observables, focusing on the contributions of third-generation four-quark operators. …”

    Effective field theory approach to lepton number violating decays K±→ π∓l±l±: short-distance contribution by Yi Liao, Xiao-Dong Ma, Hao-Lin Wang

    Published 2020-01-01
    “…Assuming the standard model effective field theory (SMEFT) is the appropriate effective field theory between some new physics scale and the electroweak scale, we match our LEFT results to SMEFT whose leading effective interactions arise from LNV dim-7 operators. …”

    Interplay of chiral transitions in the standard model by Holger Gies, Richard Schmieden, Luca Zambelli

    Published 2025-01-01
    “…We focus on the chiral symmetry breaking mechanisms provided by the QCD and the electroweak sectors, the latter of which we model by a Higgs-top-bottom Yukawa theory. …”

    Large CP violation in flavor violating muon decays by Diego Redigolo, Michele Tammaro, Andrea Tesi

    Published 2025-01-01
    “…We tackle this issue by performing the full one-loop running and matching from the low energy observables at the muon scale, including the T-odd asymmetry in $$\mu \rightarrow 3e$$ μ → 3 e decays, to the Standard Model effective field theory above the electroweak scale. We then sketch a simple UV model that can give rise to these patterns.…”

    Nonstandard Neutrinos Interactions in a 331 Model with Minimum Higgs Sector by M. Medina, P. C. de Holanda

    Published 2012-01-01
    “…We present a detailed analysis of a class of extensions to the SM Gauge chiral symmetry SU ( 3 ) C ×SU ( 3 ) L ×U ( 1 ) x (331 model), where the neutrino electroweak interaction with matter via charged and neutral current is modified through new gauge bosons of the model. …”

    Exploring SMEFT couplings using the forward–backward asymmetry in neutral current Drell–Yan production at the LHC by the xFitter Developers’ team

    Published 2024-12-01
    “…Besides recovering earlier results on the $$A_{\textrm{FB}}$$ A FB sensitivity to parton distribution functions, we analyze the precision determination of Z-boson couplings to left-handed and right-handed u-quarks and d-quarks, and explore Beyond-Standard-Model contributions using the Standard Model Effective Field Theory (SMEFT) framework. We perform a sensitivity study and comment on the role of the $$A_{\textrm{FB}}$$ A FB asymmetry for the electroweak SMEFT fit and precision Z-boson physics at the LHC and high-luminosity HL-LHC.…”

    Groups Which Contain the Diffeomorphisms and Superdiffeomorphisms as Proper Subgroups by Dave Pandres

    Published 2013-01-01
    “…We used this larger group to unify the gravitational and electroweak fields, which are mediated by bosons. Unfortunately, we could not include the neutrinos, because geometrical theories based on an ordinary manifold generally cannot include fermions. …”
