Two-gluon rapidity correlations of strong colour field in $pp$, $pA$ and $AA$ collisions

Ye-Yin Zhao, Ming-Mei Xu, Heng-Ying Zhang +1

Using the CGC formalism, we calculate the two-gluon rapidity correlations of strong colour fields in $pp$, $pA$ and $AA$ collisions, respectively. If one trigger gluon is fixed at…
