摘要： We calculate the one-loop QCD corrections to t → t ̃ χ ̃0 using dimensional reduction scheme, including QCD and supersymmetric QCD corrections. The analytic expressions for the corrections to the decay width are given, which can easily be extended to t → χ ̃+j ̃bi. The numerical results show that the correction amounts to more than a 10% reduction in the partial width relative to the tree level result. We also compare the corrections in the no-mixing stop case with those in the mixing stop case.

摘要： We investigate the ability of single top quark production via qq'-> squark->tb and q \bar q'->slepton->t\bar b at the LHC and Tevatron to probe the strength of R-parity violating couplings in the minimal supersymmetric model. We found that given the exist

摘要： We investigate the possibility of observing the exotic decay mode of the top quark into the lightest stop (t~1t~1\tilde t_1) and neutralino (χ~01χ~10\tilde\chi^0_1) in the minimal supersymmetric standard model with R-parity at the upgraded Tevatron. First

摘要： In the next-to-minimal supersymmetric model (NMSSM) a light CP-odd Higgs boson is so far allowed by current experiments, which, together with a large tanβtan?β\tan\beta, may greatly enhance the rare dileptonic decays B\to X_s l^+ l^- and B_s\to l^+ l^- \g
