Probe New Physics in Leptonic $B_c$ Decays at CERN LHC

Abstract

With respect to large samples of $B_c$ mesons expected to be produced at CERN Large Hadron Collider(LHC) and the large branching ratios $Br(B_c\to \tau \bar{\nu })$ and $Br(B_c\to \mu \bar{\nu })$, we suggest that $B_c$ purely leptonic decays could offer an unique probe of the standard model and its extensions such as two Higgs doublet models and models involving supersymmetry, and also the structure of charged weak currents.
