Abstract
We present the latest measurements of ϒ production in Au+Au collisions at sNN=200GeV via both di-muon and di-electron decay channels by the STAR experiment at RHIC. With the addition of the 2016 data set to those taken in 2011 and 2014, the precision of ϒ measurements is significantly improved compared to previous preliminary results, especially for the excited ϒ states. The nuclear modification factors for the ground and excited ϒ states are shown as a functions of transverse momentum or centrality, and are compared to results from the LHC as well as to theoretical calculations.
