相干态方法在消除LFQED各阶红外发散中的应用

Application of Coherent State Approach for the cancellation of Infrared divergences to all orders in LFQED

Jai More, Anuradha Misra

摘要:

利用相干态理论,给出了光锋量子电动力学中红外发散抵消的全阶证明。本文指出,如果用相干态基代替通常的Fock基来计算哈密顿矩阵元,那么在光阵面时间序微扰计算中,费米子自能的真实红外发散将被消除到所有阶。

英文摘要:

We sketch an all order proof of cancellation of infrared (IR) divergences in Light Front Quantum Electrodynamics (LFQED) using a coherent state formalism. In this talk, it has been shown that the true IR divergences in fermion self energy are eliminated to all orders in a light-front time-ordered perturbative calculation if one uses coherent state basis instead of the usual Fock basis to calculate the Hamiltonian matrix elements.
