B衰变到$τν$的R-宇称破坏的提示

Hints of R-parity violation in B decays into $τν$

N. G. Deshpande, A. Menon

摘要:

在本文中,我们表明,最近观察到的增强的半轻子和轻子衰变到τν模的B介子的R宇称破坏(RPV)MSSM框架内的工作可以解释。特别地,涉及右手向下型方子交换的RPV贡献对B+ -> τν,B --> D τν和B --> D* τν衰变具有普遍贡献。我们发现,质量和耦合,解释增强B衰变率是phenomelogically可行的,并有可能在大型强子对撞机观察到的squarks。

英文摘要:

In this article we show that the recently observed enhanced semi-leptonic and leptonic decay rates of the B meson into τνmodes can be explained within the frame work of R-parity violating (RPV) MSSM. In particular, RPV contributions involving the exchange of right-handed down-type squarks give a universal contribution to the B+ --> τν, B --> D τνand the B --> D* τνdecays. We find that the masses and couplings that explain the enhanced B decay rates are phenomelogically viable and the squarks can possibly be observed at the LHC.
