pair production

The conversion of a high-energy (>1.022 MeV) gamma-ray photon, usually in the field of an atomic nucleus, into an electron and positron, which are formed simultaneously. See also annihilation; photon-photon absorption.

Therefore, with the lepton formation and quark-antiquark pair production model developed in this paper, we can understand the recent measurement of a tau particle in a muon neutrino beam as well as the early measurements of muon particles in electron neutrino beams.
This paper develops a quark-antiquark annihilation and pair production model to explain the formation of leptons and the oscillation of neutrinos and further predict the fourth generation of leptons named as lambda particle and neutrino.
