Threshold and Flavour Effects in the Renormalization Group Equations of the MSSM I: Dimensionless Couplings

Andrew D. Box, Xerxes Tata

In a theory with broken supersymmetry, gaugino couplings renormalize differently from gauge couplings, as do higgsino couplings from Higgs boson couplings. As a result, we expect t…
