New Formulas and Predictions for Running Masses at Higher Scales in MSSM

TL;DR

This paper derives new one-loop formulas for running quark-lepton masses at higher scales in MSSM, accounting for scale-dependent Higgs VEVs and including two-loop effects, with implications for mass predictions and Yukawa coupling effects.

Contribution

It introduces novel analytical formulas for running masses in MSSM that incorporate scale-dependent Higgs VEVs and two-loop corrections, differing from previous models.

Abstract

Including contributions of scale-dependent vacuum expectation values of Higgs scalars, we derive new one-loop formulas analytically for running quark-lepton masses at higher scales in MSSM. Apart from the gauge-coupling dependence being different from earlier formulas, the third-generation- Yukawa-coupling effects are absent in the masses of the first two generations. While predicting the masses and $\tan\beta$ numerically, we also include two-loop effects.
