Dine Ousmane Samary, Emanonfi Elias N'Dolo, Mahouton Norbert Hounkonnou

摘要:

计算了$(d+1)-$维非对易Moyal空间中费米子粒子对产生的几率。利用Seiberg-Witten映射建立了非对易场变量和对易场变量之间的关系,在非对易参数$θ$的一阶下,我们导出了Dirac粒子真空-真空对产生的概率密度。考虑和讨论了恒定电磁场、交变时变电场和交变空变电场的情况。

英文摘要:

This work addresses the computation of the propability of fermionic particle pair production in $(d+1)-$ dimensional noncommutative Moyal space. Using the Seiberg-Witten maps that establish relations between noncommutative and commutative field variables, to first order in the noncommutative parameter $θ$, we derive the probability density of vacuum-vacuum pair production of Dirac particles. The cases of constant electromagnetic, alternating time-dependent and space-dependent electric fields are considered and discussed.
