#CMSPaper 1245: This paper studies if Υ bosons (made of a b quark-antiquark pair) get stopped differently in proton-lead as in lead-lead collisions. This is interesting because that is the case for particles made of c quarks. For the Y it is not, showing that very heavy quarks interact differently with very dense systems (like the quark-gluon-plasma) https://arxiv.org/abs/2310.03233
