Higgs Boson masses and B-Physics Constraints in Non-Minimal Flavor Violating SUSY scenarios

TL;DR

This paper calculates one-loop corrections to Higgs boson masses in the MSSM with general flavor mixing, considering B-physics constraints, and finds significant corrections especially at low tan beta, which could refine parameter bounds.

Contribution

It provides the first comprehensive calculation of Higgs mass corrections in non-minimal flavor violating MSSM including B-physics constraints.

Findings

Corrections to Higgs masses can exceed tens of GeV.

Significant corrections are mainly at low tan beta.

Constraints from B-physics data limit flavor violation parameters.

Abstract

We present one-loop corrections to the Higgs boson masses in the MSSM with Non-Minimal Flavor Violation. The flavor violation is generated from the hypothesis of general flavor mixing in the squark mass matrices, and these are parameterized by a complete set of delta^XY_ij (X, Y = L,R; i; j = t, c, u or b, s, d). We calculate the corrections to the Higgs masses in terms of these delta^XY_ij taking into account all relevant restrictions from B-physics data. This includes constraints from BR(B -> Xs gamma), BR(Bs -> mu+ mu-) and delta M_B_s . After taking into account these constraints we find sizable corrections to the Higgs boson masses, in the case of the lightest MSSM Higgs boson mass exceeding tens of GeV. These corrections are found mainly for the low tan beta case. In the case of a Higgs boson mass measurement these corrections might be used to set further constraints on delta^XY_ij.
