Manifestation of an excited electron in e⁺e⁻ → γγ reaction
The differential cross section and some polarization observables have been calculated for the e⁺e⁻ → γγ reaction taking into account the contribution of the excited electron. The spin correlation coefficients were calculated for the case when both beams are polarized. We consider two approaches for...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The differential cross section and some polarization observables have been calculated for the e⁺e⁻ → γγ reaction taking into account the contribution of the excited electron. The spin correlation coefficients were calculated for the case when both beams are polarized. We consider two approaches for the excited electron contribution: the eeγγ contact interaction and the exchange of the excited electron in t- and u-channels. Numerical estimations are given for the excited electron contribution to the differential cross section and spin correlation coefficients for various values of the electron beam energy and excited electron mass. |
