在U(1)规范场理论中,用Feynman路径积分方法,简明地显示了:(1)鬼粒子对真空能量(Casimir能量)的贡献;(2)不同的协变规范对真空能量的影响。The contribution of the ghost particle to the vacuum energy (Casimir energy) and the influence of various covariant gauges on the vacuum energy are calculated in the U(l) gauge field theory by using the Peynman path integral method.
