6. Flavor hierarchy of jet quenching in relativistic heavy-ion collisions

Wen-Jing XING

Relativistic heavy-ion experiments have observed similar quenching effects for (prompt) $D$ mesons compared to charged hadrons for transverse momenta larger than 6-8 GeV, which remains a mystery since heavy quarks typically lose less energies in quark-gluon plasma than light quarks and gluons. Recent measurements of the nuclear modification factors of $B$ mesons and $B$-decayed $D$ mesons by...

5. Parton Energy Loss and the Generalized Jet Transport Coefficient

We revisit radiative parton energy loss in deeply inelastic scattering (DIS) off a large nucleus within the perturbative QCD approach. We calculate the gluon radiation spectra induced by double parton scattering in DIS without collinear expansion in the transverse momentum of initial gluons as in the original high-twist approach. The final radiative gluon spectrum can be expressed in terms of...

15. Measurements of semi-inclusive recoil jet production and modification in pp and PbPb collisions at $\sqrt{s}$ = 5.02 TeV

The measurement of reconstructed jets over a wide range in jet energy and jet resolution parameter 𝑅 is required for comprehensive understanding of jet quenching in heavy-ion collisions. Such measurements are challenging, however, due to the presence of complex, uncorrelated background to the jet signal, and the need to minimize biases in the selected jet population imposed by background...

7. Light Nuclei ($d$, $t$) Production in Au+Au Collisions at $\sqrt{s_{\rm{NN}}}$=7.7-200 GeV from the STAR experiment

In high energy nuclear collisions, light nuclei can be regarded as a cluster of baryons and their yields are sensitive to the baryon density fluctuations. Thus, the production of light nuclei can be used to study the QCD phase transition, at which the baryon density fluctuation will be enhanced. For example, the ratio of proton ($N(p)$) and triton ($N(t)$) to deuteron ($N(d)$) yields, which...

10. Holographic Schwinger effect and the energy loss of quarks in the magnetized background

Zhou-Run ZHU

We study the magnetic field effect on the Schwinger effect and the energy loss of quarks using the AdS/CFT correspondence. The potential analysis of particle pairs transverse and parallel to the magnetic field is performed in this paper. Firstly, we calculate separating length of the particle pairs at finite temperature with magnetic field. It is found that the maximum value of separating...
