Lepton Flavor Violation in Supersymmetric SO(10) Grand Unified Models

Xiao-Jun Bi, Yuan-Ben Dai, Xiao-Yuan Qi

The study for lepton flavor violation combined with the neutrino oscillation may provide more information about the lepton flavor structure of the grand unified theory. In this pap…

Signatures of MSSM charged Higgs bosons via chargino-neutralino decay channels at the LHC

Mike Bisset, Monoranjan Guchait, Stefano Moretti

We assess the potential of detecting a charged Higgs boson of the MSSM at the LHC via its decays into a chargino and a neutralino. We focus our attention on the region of parameter…

Renormalizaion group equations and infrared quasi fixed point behaviors of non-universal soft terms in MSSM

Chao-Shang Huang, Liao Wei, Qi-Shu Yan +1

The renormalization group equations(RGEs) of non-universal soft supersymmetric breaking terms with CP violating phases are analyzed in this paper. We obtain the analytic solutions…

B_s \to \ell^+ \ell^- in a model II 2HDM and MSSM

Chao-Shang Huang, LIAO Wei, Qi-Shu Yan +1

In this paper we analyze the process in a model II 2HDM and MSSM. All the leading terms of Wilson coefficients relevant to the process are given in the larg…

Higgs radiation off quarks in supersymmetric theories at e^+e^- colliders

S. Dittmaier, M. Krämer, Y. Liao +2

Yukawa couplings between Higgs bosons and quarks in supersymmetric theories can be measured in the processes e^+e^- -> Q Qbar + Higgs. We have determined the cross sections of thes…

Reexamination of the Constraint on Topcolor-Assisted Technicolor Models from R_b

Chongxing Yue, Yu-Ping Kuang, Xue-Lei Wang +1

Recent study on the charged top-pion correction to R_b shows that it is negative and large, so that the precision experimental value of R_b gives rise to a severe constraint on the…
