Title: A limit for the mu -> e gamma decay from the MEG experiment

A search for the decay mu -> e gamma, performed at PSI and
based on data from the initial three months of operation of the MEG
experiment, yields an upper limit
BR(mu -> e gamma) < 2.8 x 10**-11 (90% C.L.).
Positrons and photons from ~ 10**14 stopped mu-decays
were measured by a superconducting positron spectrometer and a
900 litre liquid xenon photon detector.
