Threshold Corrections to the Bottom Quark Mass Revisited

Understand

Threshold corrections to the bottom quark mass are often estimated under the approximation that tan$\beta$ enhanced contributions are the most dominant.

• In this work we revisit this common approximation made to the estimation of the supersymmetric threshold corrections to the bottom quark mass.
• We calculate the full one-loop supersymmetric corrections to the bottom quark mass and survey a large part of the phenomenological MSSM parameter space to study the validity of considering only the tan$\beta$ enhanced corrections.
• Our analysis demonstrates that this approximation underestimates the size of the threshold corrections by $\sim$12.5% for most of the considered parameter space.
