Mapping between γ 5 schemes in the Standard Model Effective Field Theory

Journal of High Energy Physics
We explore the relation between two distinct prescriptions for γ 5 in dimensional regularization — the Breitenlohner Maison t’Hooft Veltman (BMHV) scheme and Naive Dimensional Regularisation (NDR).

Dimension-8 SMEFT contact-terms for vector-pair production via on-shell Higgsing

Journal of High Energy Physics
We derive the dimension-8 standard-model effective theory (SMEFT) contact terms relevant for vector-pair production at the LHC and lepton colliders.

Modular symmetry in the SMEFT

Modular symmetry in the SMEFT
We study the modular symmetric standard model effective field theory. We employ the stringy Ansatz on coupling structure that 4-point couplings y((4)) of matter fields are written by a product of 3-point couplings y((3)) of matter fields, i.e., y((4)) = y((3))y((3)). In this framework, we discuss the flavor structure of bilinear fermion operators and 4-

Electroweak Restoration: SMEFT and HEFT

Colliders continue to push our understanding of electroweak (EW) interactions to ever higher energies. At high energies, many observables in the broken EW theory are expected to approach the unbroken theory. This is the electroweak restoration regime, where longitudinal gauge boson production corresponds to Goldstone boson production.
