Quarkonium measurements in the STAR experiment

Original language description

Calculations of Quantum Chromodynamics on lattice showed that under conditions of high energy density or high temperature nuclear matter undergoes a phase transition from a state of quarks and gluons confined in hadrons to a deconfined state, the Quark-Gluon Plasma (QGP). Such conditions were present in first moments after the Big Bang and can be created in laboratory by colliding of heavy ions with sufficient energy. One of the most prominent signatures of QGP formation is the quarkonium suppression incentral heavyion collisions arising from the Debye screening of the quark-antiquark potential in hot and dense nuclear matter. However, cold nuclear matter effects and heavy quark recombination could influence the measured quarkonium yields. Measurements of J/psi at different collision energies can shed new light on understanding the interplay of these mechanisms for J/psi production. The production mechanism of J/psi is not well understood yet and the simultaneous measurement of J/psi
