超对称理论与稀有过程B_s→γγ

RARE B DECAYS IN SUPERSYMMETRY WITHOUT R-PARITY

应用目前文献所给出的有关 bsγ的有效拉氏量 ,计算了最小超对称模型中的 Bs→ γγ的分支比 ,发现新物理的贡献对标准模型的预言值的改变大约为 60 %左右 .

This paper perform the complete computation of the contributions to b→s+γ, b→se +e -,b→s∑v_iv_i in supersymmetric model with bilinear R-parity violation. We compare our calculations with the evaluations in SM and the experimental results. We find that the supersymmetric contributions can be quite large in those processes.
