2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/188252We present a comprehensive update of the bounds on R-Parity violating supersymmetric couplings from lepton-flavour- and lepton-number-violating decay processes. We consider tau and mu decays as well as leptonic and semi-leptonic decays of mesons. We present several new bounds resulting from tau, eta and Kaon decays and correct some results in the literature concerning B-meson decays.30 pages; changed title, updated some bounds from the literature from different references, added referencesHigh Energy Physics - Phenomenologytext
