U(N) 规范理论中的 Bogomolny-Prasad-Sommerfield (BPS) 涡旋有两层,分别对应于非阿贝尔通量和阿贝尔通量,其宽度主要取决于 U(1) 和 SU(N) 规范耦合的比率。我们通过数值和分析发现,具有适当量子数的最轻质量粒子的宽度与康普顿长度显着不同。
Bogomolny–Prasad–Sommerfield (BPS) vortices in U(N) gauge theories have two layers corresponding to non-Abelian and Abelian fluxes, whose widths depend nontrivially on the ratio of U(1) and SU(N) gauge couplings. We find numerically and analytically that the widths differ significantly from the Compton lengths of lightest massive particles with the appropriate quantum number.
