Abstract

We put constraints on several products of R-parity violating \ensuremathλ\ensuremathλ^\ensuremath' and \ensuremathλ^\ensuremath'\ensuremathλ^\ensuremath' type couplings from leptonic and semileptonic \ensuremathτ, B_d, and B_s decays. Most of them are one to two orders of magnitude better than the existing bounds, and almost free from theoretical uncertainties. A significant improvement of these bounds can be made in high luminosity tau charm or B factories.
