Abstract
We present a measurement of the inclusive production of mesons in U+U collisions at GeV at midrapidity . Previous studies in central Au+Au collisions at GeV show a suppression of production relative to expectations from the yield in p+p collisions scaled by the number of binary nucleon-nucleon collisions , with an indication that the state is also suppressed. The present measurement extends the number of participant nucleons in the collision () by 20% compared to Au+Au collisions, and allows us to study a system with higher energy density. We observe a suppression in both the and yields in central U+U data, which consolidates and extends the previously observed suppression trend in Au+Au collisions.
