Insights into Charm and Beauty Particles in Quark-Gluon Plasma Revealed by ALICE Measurements
The ALICE collaboration at CERN has conducted new measurements on the dynamics of charm and beauty particles in quark-gluon plasma. By analyzing non-head-on lead-lead collisions, they compared the elliptic flow of prompt D mesons (produced right after the collisions) with that of non-prompt D mesons (produced later in the decays of B mesons). The results show that the elliptic flow of non-prompt D mesons is weaker than that of prompt D mesons, confirming expectations and shedding light on the thermalization of beauty quarks. These findings pave the way for further measurements in the future.
