DOI: 10.1007/jhep06(2025)106

Abstract: We calculate two-loop renormalization group equations (RGEs) in the Standard Model Effective Field Theory (SMEFT) with right-handed neutrinos, i.e., the so-called νSMEFT, up to dimension five. Besides the two-loop RGEs of dimension-five (dim-5) operators, we… read more here.

DOI: 10.1007/jhep06(2025)134

Abstract: The presence of an infinite number of marginal four-fermion operators is a key characteristic of the two-dimensional Gross-Neveu model. In this study, we investigate the structure of UV divergences in this model, and by symmetry… read more here.

DOI: 10.1088/1751-8121/ae0798

Abstract: The quantum action for a three-dimensional real sextic model using the background field method is considered. Four-loop renormalization of this model is performed with a cutoff regularization in the coordinate representation. The coefficients for the… read more here.

DOI: 10.1103/physrevd.111.016012

Abstract: For the minimal supersymmetric Standard Model, from the gauge couplings, Yukawa couplings, and the coefficient μ in the part of the superpotential quadratic in the Higgs superfields, we construct combinations which (for certain renormalization prescriptions)… read more here.
