Exclusive semileptonic B ->pi(+)pi(-)l(+)l(-) decay beyond the standard model

A systematic analysis for the exclusive rare B --> pi (+)pi (-)l(+)l(-) decay beyond the standard model is presented. The dependence of the various physically measurable asymmetries and CP violating asymmetry on the new Wilson coefficients is studied in detail. It is observed that different measurable quantiles are very sensitive to the different new Wilson coefficients, i.e., to the existence of new physics beyond the standard model.
