A Hamiltonian Based Source Theory Approach to Non-relativistic Gravitational Bremsstrahlung
摘要
Based on the Hamiltonian approach to the source theory, the scattering cross-section of gravitational bremsstrahlung of a charged particle scattering off the Coulomb potential is provided. It is shown that the cross section can be obtained by calculating the imaginary part of the effective action defined in terms of the persistence amplitude of the combined particle-graviton state
