强耦合规范理论的广义Lorentz-Dirac方程

Generalized Lorentz-Dirac Equation for a Strongly-Coupled Gauge Theory

Mariano Chernicoff, J. Antonio Garcia, Alberto Guijosa

摘要:

本文利用AdS/CFT对应,导出了强耦合大N_c N=4超杨-米尔斯系统中复合夸克的半经典运动方程.由此产生的非线性方程包括辐射阻尼,并减少到标准的洛伦兹-狄拉克方程的外力是小规模的夸克康普顿波长,但没有自加速或预加速的解决方案。从这个方程中可以读出夸克的非标准色散关系,以及辐射率的洛伦兹协变公式。

英文摘要:

We derive a semiclassical equation of motion for a `composite' quark in strongly-coupled large-N_c N=4 super-Yang-Mills, making use of the AdS/CFT correspondence. The resulting non-linear equation incorporates radiation damping, and reduces to the standard Lorentz-Dirac equation for external forces that are small on the scale of the quark Compton wavelength, but has no self-accelerating or pre-accelerating solutions. From this equation one can read off a non-standard dispersion relation for the quark, as well as a Lorentz covariant formula for its radiation rate.
