The theoretical cleaness of this decay constitutes a useful way to provide constraints, independent of long distance effects. Including the possiblity of interferences between one-loop R-parity conserving (RPC) supersymmetry and tree-level RPV supersymmetric contributions, our results allow to improve the limits on R-parity violating couplings with respect to previous analyses.4 pages, 2 figures, Moriond EW 2005High Energy Physics - Phenomenologytext
