Relating Bottom Quark Mass in DR and MS Regularization Schemes

摘要

Supersymmetry (SUSY) is one of the best-studied extensions of the Standard Model (SM). Despite the lack of direct evidence, many theorists consider the idea promising enough to examine even quantum corrections in SUSY theories: these include corrections to SM quantities due to sparticle loops, as well as corrections to processes involving the production and decays of supersymmetric particles. Quantum corrections in SUSY theories are also important for obtaining the implications of top-down models, where simple assumptions about symmetries of physics at the high scale result in a highly predictive scenario. The best known example of these is the correction to the relation between the down type mass and the corresponding superpotential Yukawa coupling, which is crucial to include when analyzing SUSY models for large values of the parameter.
