非最小pp波Einstein-Yang-Mills-Higgs模型:曲率引起的色交叉效应

Non-minimal pp-wave Einstein-Yang-Mills-Higgs model: color cross-effects induced by curvature

Alexander B. Balakin, Heinz Dehnen, Alexei E. Zayats

摘要:

在pp波Einstein-Yang- Mills - Higgs(EYMH)模型中,非最小相互作用会产生类似于Maxwell理论中磁电效应的色交叉效应。为了说明这些颜色交叉效应的意义,我们重建有效的(相关的,颜色和颜色声学)的PP波非最小的七参数EYMH模型与平行规范和标量背景场的度量。然后,利用这些度规,得到了在曲率作用下的真空中传播的非极小扩展的Yang-Mills方程和Higgs方程的显式精确解.非最小耦合对测试粒子运动的影响被解释为在模拟重力理论中引入的所谓的捕获表面。

英文摘要:

Non-minimal interactions in the pp-wave Einstein - Yang - Mills - Higgs (EYMH) model are shown to give rise to color cross-effects analogous to the magneto-electricity in the Maxwell theory. In order to illustrate the significance of these color cross-effects, we reconstruct the effective (associated, color and color-acoustic) metrics for the pp-wave non-minimal seven-parameter EYMH model with parallel gauge and scalar background fields. Then these metrics are used as hints for obtaining explicit exact solutions of the non-minimally extended Yang-Mills and Higgs equations for the test fields propagating in the vacuum interacting with curvature. The influence of the non-minimal coupling on the test particle motion is interpreted in terms of the so-called trapped surfaces, introduced in the Analog Gravity theory.
