3+1维非阿贝尔弦的真空能

Vacuum Energies of Non--Abelian String--Configurations in 3+1 Dimensions

H. Weigel, M. Quandt, N. Graham, O. Schroeder

摘要:

本文发展了一种在非阿贝尔规范理论中计算费米子对类弦组态真空极化能贡献的方法。这一计算以前曾受到一些技术障碍的阻碍。我们利用能量的规范不变性和能量密度中长度尺度的分离来克服这些障碍。我们提出了一个证明的原则调查表明,这个能量是小的MS-酒吧重整化方案。推广到其他方案是直截了当的。

英文摘要:

We develop a method to compute the fermion contribution to the vacuum polarization energy of string--like configurations in a non--abelian gauge theory. This calculation has been hampered previously by a number of technical obstacles. We use gauge invariance of the energy and separation of length scales in the energy density to overcome these obstacles. We present a proof-of-principle investigation that shows that this energy is small in the MS-bar renormalization scheme. The generalization to other schemes is straightforward.
