Abstract
A search for second and third generation scalar and vector leptoquarks produced in ep collisions via the lepton flavour violating processes epâμX and epâÏX is performed by the H1 experiment at HERA. The full data sample taken at a centre-of-mass energy s=319 GeV is used for the analysis, corresponding to an integrated luminosity of 245 pbâ1 of e+p and 166 pbâ1 of eâp collision data. No evidence for the production of such leptoquarks is observed in the H1 data. Leptoquarks produced in e±p collisions with a coupling strength of λ=0.3 and decaying with the same coupling strength to a muon-quark pair or a tau-quark pair are excluded at 95% confidence level up to leptoquark masses of 712 GeV and 479 GeV, respectively.
