Abstract

One of the candidates for dark matter particles is the heavy photon. The experiment on the search for these particles using nuclear emulsions irradiated in a positron beam with an energy of 32 GeV is described. Methodical studies for estimating the efficiency of the search for electronpositron pairs and the effective mass determination accuracy are performed.
