关于有效场论的非微扰重整化的注记

A note on nonperturbative renormalization of effective field theory

J. -F. Yang

摘要:

在接触势的范围内,利用代数Lippmann-Schwinger方程的严格解和逆形式,揭示了$T$ -矩阵非微扰重整化的内在关键结构.有效场论的功率计数和非微扰发散结构之间的内在失配的第一次排除了传统的counterterterm算法的工作在重整化的EFT $NN$散射在非微扰制度。

英文摘要:

Within the realm of contact potentials, the key structures intrinsic of nonperturbative renormalization of $T$-matrices are unraveled using rigorous solutions and an inverse form of algebraic Lippmann-schwinger equation. The intrinsic mismatches between effective field theory power counting and nonperturbative divergence structures are shown for the first time to preclude the conventional counterterm algorithm from working in the renormalization of EFT for $NN$ scattering in nonperturbative regimes.
