Upsilon measurements in pp, pPb abd PbPb collisions
The CMS experiment enables the measurement of the three Upsilon states Υ ( 1 S ) , Υ ( 2 S ) , Υ ( 3 S ) in pp, pPb and PbPb collisions. The PbPb measurements at 2.76 TeV as a function of event centrality shows that less stable excited states are more suppressed than ground state, a phenomenon terme...
