charmed baryon enhancement observed in heavy-ion collisions at RHIC

May 01, 2020

Enhancement of Charmed baryon over meson ratio observed in heavy-ion collisions at RHIC provides important evidence of different hadronization mechanisms of charmed hadrons in hot QGP matter compared with cold/small system. [Phys. Rev. Lett. 118 (2020) 212301].

too heavy to be moved - heaviest quark flow observed at RHIC

June 21, 2019

Non-zero beauty quark flow was observed but less than charm quark flow and NCQ scaling hypothesis, indicating beauty is unlikely thermalized and too heavy to be moved in the partonic expansion of the nuclear matter [Phys. Lett. B805 (2020) 135465].

Discovery of brownian motion of heavy quark in fermi scale.

May 26, 2017

Brownian motion in fermi scale was observed via heavy quark diffusion in the evolution of the hot quark-gluon plasma [Phys. Rev. Lett. 118 (2017) 212301].
