对具有背景电场的QED的评述

Comments on QED with background electric fields

E. T. Akhmedov, E. T. Musaev

摘要:

众所周知,在QED和量子引力等幺正相互作用场论中,\emph{factorizable} IR发散是完全抵消的。本文证明了在背景电场可以产生电子对的QED中不存在这种抵消。不存在IR发散的因式分解。

英文摘要:

It is well known that there is a total cancellation of the \emph{factorizable} IR divergences in unitary interacting field theories, such as QED and quantum gravity. In this note we show that such a cancellation does not happen in QED with background electric fields which can produce pairs. There is no factorization of the IR divergences.
