Large enhancement of D±→e±ν and D±s→e±ν in R-parity violating SUSY models
Creators
Description
The purely leptonic decays D±→e±ν and D±s→e±ν, for which no experimental limits exist, are highly suppressed in the Standard Model. Mere observation of these decays at the B factories Belle/BaBar or forthcoming CLEO-c would be a clear signal of physics beyond the SM. We show that R-parity violating slepton contributions can give rise to spectacular enhancements of the decay rates, resulting in branching ratios as large as 5x10-3, which strongly motivates a search in these channels
