Vacuum Structure of Yang-Mills Theory in Curved Spacetime

Samuel J. Collopy

摘要:

研究了QCD中色磁Savvidy真空在正黎曼曲率影响下的稳定性。在S^2和S^1的乘积空间\times S^1上计算了与SO(2)规范不变的Yang-Mills场和Faddeev-Popov鬼场有关的算符的热迹.结果表明,具有协变恒色磁场的色磁真空在一定的半径和场强下是稳定的。

英文摘要:

The stability of the chromomagnetic Savvidy vacuum in QCD under the influence of positive Riemannian curvature is studied. The heat traces of the operators relevant to SO(2) gauge-invariant Yang-Mills fields and Faddeev-Popov ghosts are calculated on product spaces of S^2 and S^1 \times S^1. It is shown that the chromomagnetic vacuum with covariantly constant chromomagnetic field is stable in a certain set of radii and field strengths.
