Large top and bottom Yukawa couplings in minimal supersymmetry
ABSTRACT We present analytic expressions for the top and bottom Yukawa couplings in the context of the minimal supersymmetric standard model when both couplings h_{t,0},h_{b,0} are large at the unification scale. For sufficiently large h_{t,0},h_{b,0}, using as input the central value of the bottom...

| Sumario: | ABSTRACT We present analytic expressions for the top and bottom Yukawa couplings in the context of the minimal supersymmetric standard model when both couplings h_{t,0},h_{b,0} are large at the unification scale. For sufficiently large h_{t,0},h_{b,0}, using as input the central value of the bottom mass m_b(m_b)=4.25GeV, we find that the top mass lies in the range m_t \approx (174-178)GeV, while tan\beta \approx (55-58). Implications on the evolution of the scalar masses and the radiative symmetry breaking scenario are discussed. |
