Sažetak
A search was made for a new light gauge boson X which might be produced in pi^0--gamma + X decay from neutral pions generated by 450-GeV protons in the CERN SPS neutrino target. Th e X's would penetrate the downstream shielding and be observed in the NOMAD detector via the Primakoff effect, in the process of X --pi^0 conversion in the external Coulomb field of a nucleus. With 1.45x10^18 protons on target, 20 candidate events with energy between 8 and 140 GeV were found from the analysis of neutrino data.This number is in agreement with the e xpectation of 18.1?2.8 background events from standard neutrino processes.A new 90 % ~C.L. upper limit on the branching ratio Br(?0?? + X) (3.3~to~1.9)?10-5 for X masses ranging from 0 to 120 MeV/c2 is obtained.
