DESCRIPTION:Speakers: Pooja - (Indian Institute of Technology Goa)\nThe hi
 gh-energy collisions can be viewed as collision of two colored glasses usi
 ng the Color-Glass condensate (CGC) picture. It results in the production 
 of the strong coherent gluon fields known as Glasma. The colored electric 
 and magnetic fields evolve by the means of Classical Yang-Mills (CYM) equa
 tions. The lifetime of this pre-equilibrium stage is of the order of forma
 tion and thermalization time of Quark-Gluon Plasma (QGP)\, typically a sho
 rt fraction of fm/c.\n\nHeavy quarks (HQs) produced in the early phase of 
 the ultra-relativistic heavy-ion collisions are efficient probes each for 
 the pre-equilibrium Glasma phase and the equilibrated quark-gluon plasma. 
 We study the diffusion of the HQs in the evolving Glasma (EvGlasma) using 
 Wong’s equations. We compare the transverse momentum broadening\, $\\sig
 ma_p$ of the HQs in the evolving Glasma fields with that of a standard\, M
 arkovian-Brownian motion in a thermalized medium with the same energy dens
 ity of the Glasma fields. We observe that the $\\sigma_p$ of HQs increases
  non-linearly during the very early time in the Glasma\, suggesting heavy 
 quarks super-diffuse in the gluon fields. We also find that for a smaller 
 value of saturation scale\, $Q_s$\, the average transverse momentum broade
 ning is approximately the same for the two cases\, but for a larger value 
 of $Q_s$\, Langevin dynamics underestimates the $\\sigma_p$. Adding to thi
 s\, we are also studying the anisotropic angular momentum flow of HQs in t
 he Glasma\, and we present some preliminary interesting results.\n\nhttps:
