Pair production of particles with spin 5/2 in colliding electron-positron beams

The process is considered. Expressions are obtained for the effective differential cross section in the case of arbitrarily polarized leptons and for the total cross section for annihilation of an unpolarized lepton pair into a pair of particles with spin 5/2. Relations are also obtained between the invariant and physical form factors of the particles with spin 5/2.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 11, pp. 42–48, November, 1980.
