Abstract

We present a complete study of R-parity violating supersymmetric effects in thirteen exclusive and inclusive semi-leptonic b → (s, d) ν over(ν, ̄) decays; Bu+ → K(*) + ν over(ν, ̄), Bd0 → K(*) 0 ν over(ν, ̄), Bs0 → φ{symbol} ν over(ν, ̄), Bd0 → π00) ν over(ν, ̄), Bu+ → π++) ν over(ν, ̄), Bs0 → K(*) 0 ν over(ν, ̄) and B → Xs, d ν over(ν, ̄) decay modes. We find those thirteen modes are very sensitive to the constrained R-parity violating couplings. We derive stringent bounds on relevant R-parity violating couplings, which are based on all existent experimental upper limits of involved semi-leptonic decays. In addition, we also investigate the sensitivities of the branching ratios and di-neutrino invariant mass spectra to the survived R-parity violating coupling spaces. Since the experimental bounds would become much better soon through super-B, we expect that future experiments will greatly strengthen our bounds.
