Upper Limit on the Decay K + → e + ν μ + μ −

An upper limit on the branching ratio for the decay K+ → e+νμ+μ− is set at 5.0× 10−7 at 90% confidence level, consistent with predictions from chiral perturbation theory.

B s → μ + μ − decay in the Randall - Sundrum model

Abstract We investigate theBs → μ+μ− decay in the presence of a light stabilized radion, a key ingredient of the Randall-Sundrum model. The branching ratio BR(Bs → μ+μ−) in the standard model is found to be 3.65 × 10−9 (two order smaller than the experimental upper bound) and raises the hope for some new physics which can explain the deficit. We found that in this brane world model for a reason...

→ μ + μ − decay in the R - parity violating minimal supergravity

We study Bs → μ+μ− in the context of the R-parity violating minimal supergravity in the high tan β regime. We find that the lowest value of the branching ratio can go well below the present LHCb sensitivity and hence Bs → μ+μ− can even be invisible to the LHC. We also find that the present upper bound on Br(Bs → μ+μ−) puts strong constraint on the minimal supergravity parameter space. The const...

Electromagnetic suppression of the decay μ → eγ

Due to large QED anomalous dimensions of the electric and magnetic dipole operators, the rate of the rare muon decay μ → eγ is suppressed by the factor (
