New paper day! We calculate the D-measure in a hadronic vs quark-gluon plasma scenarios and compare to LHC data, finding moderate evidence for fluctuations freezing out in the quark phase. arxiv.org/abs/2504.02085

Evidence for freeze-out of charge fluctuations in the quark-gluon plasma at the LHC
The D-measure of event-by-event net-charge fluctuations was introduced over 20 years ago as a potential signal of quark-gluon plasma (QGP) in heavy-ion collisions, where it is expected to be suppresse...
