Abstract

Heavy-quarkonium states are expected to evidenciate the deconfinement of the nuclear matter into a Quark-Gluon Plasma in heavy-ion collisions. To strive conclusive information from quarkonium production modification in A+A collisions, systematic measurements of the J/ψ and Υ states in p+p, d+Au and Au+Au collisions are necessary. To accomplish this mission the STAR experiment has a Quarkonium program based on the development of specific trigger setups that take advantage of the large STAR acceptance. In this work we present the preliminary results of the J/ψ and Υ measurement in 200 GeV p+p and the first measurements of Υ in 200 GeV heavy ion collisions.
