Gravitational electron–positron scattering

A scattering process with gravitons as an intermediate state is investigated. To study such a scattering, the Gravitoelectromagnetism theory considered. It gravitational built on analogy between gravity and electromagnetism. The complete Lagrangian formulation of gravitoelectromagnetic includes interactions fermions photons that leads us to calculate their amplitudes cross sections. In this context, section \(e^{-}+e^{+}\longrightarrow \mu ^{-}+\mu ^{+}\) obtained. comparison electromagnetic sections made.
