Hints of R-parity violation in B decays into tau nu
In this article we show that the recently observed enhanced semi-leptonic and leptonic decay rates of the B meson into tau nu modes 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 can g...
