取消LFQED中所有订单的红外发散

Cancellation of Infrared divergences to all orders in LFQED

Jai D. More, Anuradha Misra

摘要:

相干态方法是光场场论中处理真红外发散的一种替代方法。我们表明,如果用相干态基代替通常的Fock基来计算哈密顿矩阵元,那么在光锋时间有序微扰理论中,费米子质量重整化的红外发散将被消除到所有的阶。

英文摘要:

Coherent state approach has been proposed as an alternate way to deal with the true infrared divergences in light front field theory. We show that infrared divergences in fermion mass renormalization are eliminated to all orders in light front time ordered perturbation theory if one uses coherent state basis instead of the usual Fock basis to calculate the Hamiltonian matrix elements.
