#CMSPaper 1225: This paper uses over 4 billion LHC lead-lead collisions to study the shape of the quark-gluon plasma using quantum-correlations, called Bose-Einstein correlations, between two particles in the collision. The conclusion: the shape of the #quarkgluonplasma is not as simple as we figured. Lévy functions describe the data (yay!), and we measure those accurately so these can be used to model/predict other collisions in the future!

#CMSPaper 1198: D mesons are two-quark particles that contain one charm quark. In this paper, the behavior of D mesons produced directly in a lead-lead collision is compared to D mesons from b quark decays, both when traversing the #quarkgluonplasma. The conclusion: charm quarks get stopped less by the QGP than bottom quarks! http://cms-results.web.cern.ch/cms-results/public-results/publications/HIN-21-003/index.html #heavyionphysics #physics #cern @CMSexperiment

Hello everyone,

I'm Maximilian Attems and working on my 2nd #MSCA postdoc at the heavy-ion group at #CERN TH.

Lately I have been calculating the medium modification of the collinear gluon splitting to charm and anti-charm inside of jets from heavy-ion collisions versus proton-proton collisions as new observable for the upcoming high-luminosity runs of the Large Hadron Collider.

#CMSPaper 1191: How are bottom quark #jets created in the #quarkGluonPlasma ? This paper measures that and the shape of the jets that are created. Such a measurement is important because this is as close as we can emulate dense places like neutron stars. http://cms-results.web.cern.ch/cms-results/public-results/publications/HIN-20-003/index.html #physics #cern #CMSExperiment
