Abstract
We calculate the cross section for the production of a hypothetical light neutral pseudoscalar particle in heavy-ion collisions due to the two-photon process. For an inverse coupling strength f in the 100-GeV range we predict a cross section of 10-14 fm2 for production of a particle with 1.5-MeV mass. For the maximal allowed coupling f=5 MeV and an effective reduction of the particle mass due to binding the cross section may reach in to the b range.
