چکیده

We consider the infrared quasi fixed point solutions of the renormalization group equations for the Yukawa couplings and soft supersymmetry breaking parameters in the MSSM in the large tan β regime. The existence of IR quasi fixed points together with the values of gauge couplings, third generation quarks, lepton and Z-boson masses allows one to predict masses of the Higgs bosons and SUSY particles as functions of the only free parameter, m 1/2 , or the gluino mass. The lightest Higgs boson mass for M SU SY ≈ 1 TeV is found to be m h = 123.

" The search for the Higgs boson is the task # 1 of high energy physics " L. Abstract The status of the Higgs boson mass in the Standard Model and its supersym-metric extensions is reviewed and the perspectives of Higgs searches are discussed. The parameter space of the Minimal Supersymmetric Standard Model (MSSM) is analysed with the emphasis on the lightest Higgs mass. The infrared behaviour ...

In the infrared fixed point (IFP) scenario of the minimal supersymmetric model (MSSM), the top-quark mass and other physical quantities of the low-energy theory are insensitive to the values of the parameters of the theory at some high energy scale. In this framework we evaluate the light CP-even Higgs mass, m h 0 , taking into account some important effects that had not been previously conside...

We show that the current LEP2 lower bound upon the MSSM lightest Higgs mass rules out quasi-fixed scenarios for string scales between 10 8 and 10 14 GeV. We consider the implications for charge and colour breaking (CCB) bounds in the MSSM, and demonstrate that CCB bounds from F and D-flat directions are significantly weakened. For scales less than 10 10 GeV these bounds become merely that degen...

It has been suggested, in connection with electroweak baryogenesis in the Minimal Supersymmetric Standard Model (MSSM), that the right-handed top squark has a negative mass squared parameter, such that its field could condense prior to the electroweak phase transition (EWPT). Thus color and electric charge could have been broken just before the EWPT. Here we investigate whether the tunneling ra...
