Spacetime structure of (3+1)D color fields in high energy nuclear collisions

Ipp A, Müller DI, Schlichting S, Singh P. Spacetime structure of (3+1)D color fields in high energy nuclear collisions. Physical Review D. 2021;104(11): 114040.We perform an analytic calculation of the color fields in heavy-ion collisions by considering the collision of longitudinally extended nuclei in the dilute limit of the Color Glass Condensate effective field theory of high-energy QCD. Based on general analytic expressions for the color fields in the future light cone, we evaluate the rapidity profile of the transverse pressure within a simple specific model of the nuclear collision geometry and compare our results to 3+1D classical Yang-Mills simulations
