强SU(2)场中产生的费米子的横动量谱和纵动量谱

Transverse and longitudinal momentum spectra of fermions produced in strong SU(2) fields

Vladimir Skokov, Peter Levai

摘要:

本文研究了在强的含时非阿贝尔SU(2)场中产生的费米子的横动量谱和纵动量谱。不同的时间依赖的场强被引入。在动力学模型中计算了产生的费米子对的动量谱。得到的谱与阿贝尔谱相似,在高p_T时,随时间的变化呈现指数或多项式形式。我们研究了不同的色初始条件,并讨论了阿贝尔和SU(2)情形下的标度性质。

英文摘要:

We study the transverse and longitudinal momentum spectra of fermions produced in a strong, time-dependent non-Abelian SU(2) field. Different time-dependent field strengths are introduced. The momentum spectra are calculated for the produced fermion pairs in a kinetic model. The obtained spectra are similar to the Abelian case, and they display exponential or polynomial behaviour at high p_T, depending on the given time dependence. We investigated different color initial conditions and discuss the recognized scaling properties for both Abelian and SU(2) cases.
