Limit on two-photon width of particle with 1.8 MeV/c2 mass
- 1. AN SSSR, Novosibirsk. Inst. Yadernoj Fiziki
Description
The process of production of the 1.8 MeV/c2 pseudoscalar particle in the experiments with heavy ions with Γee<0.01 eV decay width for the e+e--pair is discussed. Using the results of previous experiments on the two-photon e+e--pair production in the e+e- → e+e-+e+e- reaction the limit on the multiplication of a two-photon width of the particle studied and the probability of it decay into the e+e--pair equalling ΓγγBee<2 eV, is obtained
