光阵面QED的非微扰计算

Nonperturbative calculations in light-front QED

S. S. Chabysheva

摘要:

将光阵面量子化和Pauli-Villars正则化方法应用于量子电动力学中缀饰电子态的非微扰计算。这是对规范理论中方法的一个检验,作为量子色动力学非微扰解的可能方法的先驱。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:

The methods of light-front quantization and Pauli-Villars regularization are applied to a nonperturbative calculation of the dressed-electron state in quantum electrodynamics. This 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.
