We compute double and triple inclusive gluon production in p-A scattering beyond the so-called "glasma graph" approximation. We consider quantum interference effects and identify in this general setup the terms responsible for the gluon HBT and initial wave function Bose enhancement which lead to correlations in particle production. Both of these terms originate from the factorizable part of the quadrupole and sextupole terms in the production cross section. We also show that the target Bose enhancement in this regime is suppressed at large number of colors.
我们计算了质子-原子核散射中双包容和三包容胶子产生,超出了所谓的“玻璃态图”近似。我们考虑了量子干涉效应,并在这个一般框架中识别出导致胶子汉伯里-布朗-特威斯(HBT)效应和初始波函数玻色增强的项,这些项会导致粒子产生中的关联。这两个项都源于产生截面中四极和六极项的可因式分解部分。我们还表明,在这种情况下,目标玻色增强在大量色荷时会受到抑制。
