Abstract:
We obtain a new relativistic Coulomb-like resummation factor ($L$-factor) for an arbitrary orbital moment $\ell\ge0$. We work within the fully covariant quasipotential approach in quantum field theory formulated in the relativistic configuration representation in the case of two interacting relativistic particles with arbitrary masses.
Keywords:quantum field theory, relativistic configuration representation, Coulomb-like quasipotential.
