Generalized two-point tree-level amplitude $jf\to j^{\prime }{f}^{\prime }$ in a magnetized medium (extended version)

A. V. Kuznetsov, D. A. Rumyantsev, D. M. Shlenev

The tree-level two-point amplitudes for the transitions $jf\to j^{\prime }{f}^{\prime }$, where $f$ is a fermion and $j$ is a generalized current, in a constant uniform magneti…
