强恒色电背景场产生的电子对横向分布的Casimir依赖性

Casimir dependence of transverse distribution of pairs produced from a strong constant chromo-electric background field

Fred Cooper, John F. Dawson, Bogdan Mihaila

摘要:

由强的恒定色电场产生的胶子和夸克-反夸克对的横向分布取决于两个规范不变量$C_1=E^aE^a$和$C_2=[d_{abc}E^aE^bE^c]^2$,如[G. C. Nayak和P. van Nieuwenhuizen,Phys.Rev.D71,125001(2005)]中的胶子和[G.C. Nayak,Phys.Rev.D72,125010(2005)]。在这里,我们讨论的第二个Casimir不变量,C_2的分布的显式依赖,并显示的依赖是最多15%的效果。

英文摘要:

The transverse distribution of gluon and quark-antiquark pairs produced from a strong constant chromo-electric field depends on two gauge invariant quantities, $C_1=E^aE^a$ and $C_2=[d_{abc}E^aE^bE^c]^2$, as shown earlier in [G.C. Nayak and P. van Nieuwenhuizen, Phys. Rev. D 71, 125001 (2005)] for gluons and in [G.C. Nayak, Phys. Rev. D 72, 125010 (2005)] for quarks. Here, we discuss the explicit dependence of the distribution on the second Casimir invariant, C_2, and show the dependence is at most a 15% effect.
