t Hooft-Polyakov算子的BRST不变性和de Rham型上同调

BRST invariance and de Rham-type cohomology of 't Hooft-Polyakov monopole

Soon-Tae Hong

摘要:

利用t Hooft-Polyakov方法定义了量子场算符和BRST荷$Q_{BRST}$的闭代数。在Dirac量子化的第一类位形中,通过引入$Q_{BRST}$ -精确规范固定项和Faddeev-Popov鬼项,我们找到了BRST不变哈密顿量,从而研究了Dirac系统的de Rham型上同调群结构. Bogomol'nyi界也讨论了定义在扩展的内部2-球面上的第一类拓扑荷。

英文摘要:

We exploit the 't Hooft-Polyakov monopole to define closed algebra of the quantum field operators and the BRST charge $Q_{BRST}$. In the first-class configuration of the Dirac quantization, by including the $Q_{BRST}$-exact gauge fixing term and the Faddeev-Popov ghost term, we find the BRST invariant Hamiltonian to investigate the de Rham-type cohomology group structure for the monopole system. The Bogomol'nyi bound is also discussed in terms of the first-class topological charge defined on the extended internal 2-sphere.
