光阵面QED的非微扰计算简介

A brief introduction to nonperturbative calculations in light-front QED

S. S. Chabysheva

摘要:

本文在量子电动力学的背景下描述了一种求解量子场论的非微扰方法,并应用于计算电子的反常磁矩。该方法基于光阵面量化和Pauli-Villars正则化。应用于光前QED的目的是作为一个测试的方法在规范理论,作为一个先驱的可能方法的非微扰解的量子色动力学。在Fock基中,电子态被截断为最多包含两个光子而不包含正电子,并使用修饰态的波函数来计算电子的反常磁矩。保持无质量极限的手征对称性的正则化的选择是计算成功的关键。

英文摘要:

A nonperturbative method for the solution of quantum field theories is described in the context of quantum electrodynamics and applied to the calculation of the electron's anomalous magnetic moment. The method is based on light-front quantization and Pauli-Villars regularization. The application to light-front QED is intended as a test of the methods in a gauge theory, as a precursor to possible methods for the nonperturbative solution of quantum chromodynamics. The electron state is truncated to include at most two photons and no positrons in the Fock basis, and the wave functions of the dressed state are used to compute the electrons's anomalous magnetic moment. A choice of regularization that preserves the chiral symmetry of the massless limit is critical for the success of the calculation.
