Magnetic Field Effect on Charmonium Production in High Energy Nuclear Collisions
Abstract
It is important to understand the strong external magnetic field generated at the very beginning of high energy nuclear collisions. We study the effect of the magnetic field on the charmonium yield and anisotropic distribution in Pb+Pb collisions at the LHC energy. The time dependent Schr\"odinger equation is employed to describe the motion of cc pairs. We compare our model prediction of non- collective anisotropic parameter v2 of J/ with CMS data at high transverse momentum. This is the first attempt to measure the magnetic field in high energy nuclear collisions.
