On the two-loop corrections to the Higgs mass in trilinear R-parity violation

TL;DR

This paper investigates how large trilinear R-parity violating couplings affect the Higgs boson mass in supersymmetric models, using two-loop calculations with SARAH and SPheno, revealing positive corrections up to a few GeV.

Contribution

It provides the first detailed two-loop correction analysis of the Higgs mass considering large R-parity violating couplings in supersymmetry.

Findings

Positive Higgs mass corrections up to a few GeV for certain parameter ranges

Two-loop effects are significant in models with large R-parity violation

The effective potential approach effectively captures these corrections

Abstract

We study the impact of large trilinear R-parity violating couplings on the lightest CP-even Higgs boson mass in supersymmetric models. We use the publicly available computer codes SARAH and SPheno to compute the leading two-loop corrections. We use the effective potential approach. For not too heavy third generation squarks (< 1 TeV) and couplings close to the unitarity bound we find positive corrections up to a few GeV in the Higgs mass.
