J/psi PRODUCTION IN U plus U COLLISIONS AT THE STAR EXPERIMENT

Popis výsledku v původním jazyce

Quark-gluon plasma (QGP), a novel state of deconfined nuclear matter, has been studied in high-energy heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC). Due to the color screening of the quark-antiquark potential in the QGP, production of heavy quarkonia (e.g. J/psi, Upsilon) is expected to be suppressed. However, there are also other effects that may influence the observed quarkonium yields (e.g. secondary production in the QGP, cold-nuclear-matter effects). To understand those effects, we need to study production of heavy quarkonia in various colliding systems. We present preliminary results on nuclear modification factor of J/psi production at mid-rapidity via the di-electron decay channel in minimum bias U+U collisions at root s(NN) = 193 GeV at the STAR experiment and the current status of analysis of J/psi production in central U+U collisions.
