Abstract

The average number of pairs of scalar massive particles produced by a decaying photon in a radiation-dominated universe is calculated. The dependence of the expression obtained on the energy of the initial photon is investigated. Numerical estimates are found for the formative time t 0 of the processes of decay of photons in an early universe and for the total number N (±) out pair of photoproduced scalar pairs. The estimates are: t 0 ∼ 3 min and N (±) out pair ∼ 1031·N (±) 0(0), where N (±) 0(0) is the total number of pairs produced from the vacuum of a free quantized field.
