英文摘要Direct searches for lepton flavour violation in decays of the higgs and z bosons with the atlas detector at the lhc are presented. the following three decays are considered: h -> e tau, h -> mu tau, and z -> mu tau. the searches are based on the data sample of proton-proton collisions collected by the atlas detector corresponding to an integrated luminosity of 20.3 fb(-1) at a centre-of-mass energy of root s = 8 tev. no significant excess is observed, and upper limits on the lepton-flavour-violating branching ratios are set at the 95% confidence level: br(h -> e tau) < 1.04%, br(h -> mu tau) < 1.43%, and br(z -> mu tau) < 1.69 x 10(-5).
