[virtual NT/RIKEN seminar] Transverse momentum broadening in the Glasma

by Andreas Ipp (TU Wien)




Jets are hard probes that originate from initial hard scatterings of the nuclei in heavy ion collisions. They acquire transverse momentum broadening through interaction with the evolving quark-gluon plasma. However, already the pre-equilibrium Glasma stage can contribute to transverse momentum broadening. 

In this talk, I present our recent work [1] where we calculate the contribution to transverse momentum broadening from the Glasma phase. We base our calculation on the boost-invariant 2+1D Glasma description which builds upon the Color Glass Condensate framework. Interestingly, we find strong time-dependence and anisotropic results with larger momentum broadening in the direction along the beam axis.
