Abstract
The DELPHI collaboration has searched for lepton flavour violating decays tau --> mu gamma and tau --> e gamma using a data sample of about 70 pb(-1) of integrated luminosity corresponding to 81 000 produced tau(+)tau(-) events. No candidates were found for either of the two modes. This yields branching ratio upper limits of B(tau --> e gamma) < 1.1 x 10(-4) and B(tau --> mu gamma) < 6.2 x 10(-5) at 90% confidence level.
