title: Threshold Corrections to the Bottom Quark Mass Revisited
---

Introduction \[Sec:intro\]
==========================

The supersymmetric (SUSY) threshold corrections to the bottom quark mass in the large $\tanb$ regime are often expressed as an approximation of the dominant gluino-sbottom and chargino-stop loop contributions [@Hall:1993gn; @Carena:1994bv; @Blazek:1995nv],

()\^[app]{} = && (-A\_b) I(\^2, m\_[\_1]{}\^2, m\_[\_2]{}\^2) +\
&&(A\_t-) I(\^2,m\_[\_1]{}\^2,m\_[\_2]{}\^2) \[Eq:common-app\] .

In order to fit the bottom quark mass, $m_b(M_Z)^{\rm SM} = m_b(M_Z)^{\rm MSSM}\left(1 + \Delta m_b/m_b\right)$, where $m_b(M_Z)^{\rm MSSM}$ is obtained from the evolution of the bottom Yukawa coupling from a UV scale (such as the GUT scale) to the $M_Z$ scale. The effects of these supersymmetric threshold corrections are important especially in the era of precision Higgs
