Searches for Lepton Flavour Violation and Lepton Number Violation in
Hadron Decays    [PDF]

Paul Seyfert

In the Standard Model of particle physics, lepton flavour and lepton number are conserved quantities although no fundamental symmetry demands their conservation. I present recent results of searches for lepton flavour and lepton number violating hadron decays measured at the B factories and LHCb. In addition, the LHCb collaboration has recently performed a search for the lepton flavour violating decay \tau^- \to \mu^-\mu^-\mu^+. The obtained upper exclusion limit, that has been presented in this talk for the first time, is of the same order of magnitude as those observed at the B factories. This is the first search for a lepton flavour violating \tau decay at a hadron collider.
