Weak Isospin Violations In Charged And Neutral Higgs Couplings From Supersymmetric Loop Corrections, Tarek Ibrahim, Pran Nath
Weak Isospin Violations In Charged And Neutral Higgs Couplings From Supersymmetric Loop Corrections, Tarek Ibrahim, Pran Nath
Pran Nath
The supersymmetric QCD and the supersymmetric electroweak loop corrections to the violations of weak isospin to Yukawa couplings are investigated. Specifically it involves an analysis of the supersymmetric (SUSY) loop corrections to the Higgs couplings to the third generation quarks and leptons. Here we analyze the SUSY loop corrections to the charged Higgs couplings which are then compared with the supersymmetric loop corrections to the neutral Higgs couplings previously computed. It is found that the weak isospin violations can be quite significant, i.e., as much as 40–50% or more of the total loop correction to the Yukawa coupling. The effects …

Supersymmetric Qcd And Supersymmetric Electroweak Loop Corrections To B,T, And Τ Masses Including The Effects Of Cp Phases, Tarek Ibrahim, Pran Nath

We compute supersymmetric QCD and supersymmetric electroweak corrections to the b and t quark masses and to the τ lepton mass in the presence of CP phases valid for all tanβ. The analysis includes one loop diagrams arising from the exchange of gluinos, charginos and neutralinos. We find that the CP effects can change both the magnitude as well as the sign of the supersymmetric loop correction. In the region of parameter space studied we found that the numerical size of the correction to the b quark mass can be as large as 30 % and to the τ lepton …
