0. Diffusion of charm quarks in jets in high-energy heavy-ion collisions

Sa Wang

The radial distribution of $D^0$ mesons in jets probes the diffusion of charm quark relative to the jet axis and provides a new perspective to study the interaction mechanisms between heavy quarks and the medium in the nucleus-nucleus collisions. The in-medium parton propagations are described by a Monte Carlo transport model which uses the next-to-leading order (NLO) plus parton shower (PS)...

3. Non-prompt $\rm{D^0}$ meson production in pp and Pb--Pb collisions at $\sqrt{s_{\rm{NN}}} = 5.02$ TeV with ALICE

Heavy-flavor quarks (charm and beauty) play an important role in probing the Quark-Gluon Plasma (QGP) formed in the heavy-ion collisions. Due to their heavy masses, charm and beauty quarks are formed in hard scattering processes on a timescale shorter than the QGP formation time at LHC energy. Therefore, they experience all the phases of the medium evolution interacting with the medium...

Charm quarks are excellent probes of properties of Quark-Gluon Plasma (QGP) created in ultra-relativistic heavy-ion collisions. They are produced before the QGP is created and their thermalization time is comparable to the lifetime of the QGP. Compared to other open charm mesons, $D_{s}$ mesons are expected to be less sensitive to the interactions in the hadronic phase due to their...

14. Machine learning of directed percolation

In this paper, we apply the supervised learning method in deep learning to study the critical threshold, the spatial and temporal correlation exponent, and also the characteristic times of directed percolation(DP) in both (1+1) and (2+1) dimensions. DP is a classic type of absorbing phase transition in non-equilibrium phase transitions. The previous machine learning method mainly focuses on...

9. Extracting jet transport coefficient via single hadron and dihadron productions in high-energy heavy-ion collisions

We study the suppressions of high transverse momentum single hadron and dihadron productions in high-energy heavy-ion collisions based on the framework of a next-to-leading-order perturbative QCD parton model combined with the higher-twist energy loss formalism [1,2]. Our model can provide a consistent description for the nuclear modification factors of single hadron $R_{AA}$ and dihadron...
