Scientific paper

Using the upper bound on the effective number of light neutrino species during primordial nucleosynthesis and the cosmological pion-pole mechanism γγ → π0 → γX, the author obtains an upper limit on the branching ratio B for the decay π0 → γX of B < 3×10-13, where X is any long-lived weakly interacting neutral vector particle with a mass smaller than the neutral pion mass.
