Hybrid RBRC seminar

"Charm Fluctuations as a Probe for Deconfinement from Lattice QCD"

Presented by Dr Sipaz Sharma, Bielefeld

Thursday, March 16, 2023, 12:30 pm — Small Seminar Room, Bldg. 510

Abstract: We aim to establish whether charmed hadrons dissociate at the chiral crossover temperature or a higher temperature value by analyzing the second and fourth-order cumulants of charm fluctuations and their correlations with lighter conserved flavor quantum numbers, calculated on the high statistics datasets of the HotQCD Collaboration, generated with the Highly Improved Staggered Quark (HISQ) (2+1)-flavor action for light and strange quarks whereas treating the charm sector in the quenched approximation. Analyzing correlations of charm fluctuations with baryon number, electric charge and strangeness fluctuations enables us to make predictions about the not-yet-discovered charm hadrons by projecting onto charm baryonic and mesonic correlations in different sectors to compare results with Quark Model extended Hadron Resonance Gas model calculations.
