Abreu, P., Adam, W., Adye, T., Agasi, E., Ajinenko, I., Aleksan, R., ...

The DELPHI collaboration has searched for lepton flavour violating decays \tau \rightarrow \mu \gamma and \tau \rightarrow e \gamma using a data sample of about 70~pb^{-1} of integrated luminosity...

Measurement of $\Delta^{++}$(1232) production in hadronic Z decays (1995)

Abreu, P., Adam, W., Adye, T., Agasi, E., Ajinenko, I., Aleksan, R., ...

A measurement of the \Delta^{++}(1232) inclusive production in hadronic decays of the Z at LEP is presented, based on 1.3 million hadronic events collected~ by the DELPHI~ detector in the 1994 LEP...
