Summary: This article reviews recent studies on the anisotropic flows (v(1), v(2), v(3)) of charmonium in the quark-gluon plasma formed in relativistic heavy-ion collisions. It is found that the collective flows of the bulk medium are developed due to the anisotropic pressure gradient of the medium. Charm quarks, strongly coupled with the medium, carry the collective flows from the expanding medium, which are then inherited by the regenerated charmonium through the coalescence process. The initial energy density of the medium exhibits triangularity in event-by-event collisions where nucleon positions fluctuate. As a result, triangular flows of the bulk medium and heavy flavor particles can be developed. Furthermore, the rotation of the medium in non-central heavy-ion collisions induces a rapidity-odd distribution of the initial energy density in the longitudinal direction. This leads to biased dissociation of charmonium in the forward (backward) rapidity along positive and negative x-directions, resulting in non-zero directed flow of charmonium. The directed, elliptic, and triangular flows (v(1), v(2), v(3)) of charmonium arise from the anisotropic initial distributions of the medium energy density in both the transverse and longitudinal directions.

Summary: This research examines the diffusion coefficient of heavy quarks in a deconfined medium using a deep convolutional neural network trained with data from relativistic heavy ion collisions. The trained network provides parameters characterizing the temperature and momentum dependence of the diffusion coefficient by analyzing experimental data of non-prompt J/psi. The research also evaluates the uncertainty in determining the diffusion coefficient by considering the uncertainties in the experimental data.

Summary: This study investigated the effects of centrality fluctuation and deuteron formation on the cumulant and correlation functions of protons in central Au+Au collisions at 3 GeV. It was found that the centrality resolution using charged particle multiplicities is insufficient to reduce initial volume fluctuation effects for higher-order cumulant analysis. Additionally, the formation of deuterons suppresses higher-order cumulants and correlation functions of protons.

Summary: Recent experimental measurements on pp collisions at LHC energy have shown a significant production of heavy baryons, with a high Ac/D0 ratio compared to other collision modes. The application of a quark coalescence plus fragmentation approach developed for AA collisions successfully predicted the heavy baryon/meson ratio and pT spectra of charmed hadrons in pp collisions, including a significant production of S2c.

Summary: This paper investigates the medium modifications of girth distributions for inclusive jets and Z(0) tagged jets in Pb+Pb collisions at root s = 2.76 TeV at the LHC. The girth distributions of inclusive jets in Pb+Pb are shifted to lower girth regions compared to those in p+p collisions. The medium modification on girth distributions for Z(0) tagged jets is less pronounced compared to that for inclusive jets.

Summary: The axial magnetic effect (AME) is an anomalous transport phenomenon induced by an axial magnetic field. Numerical studies on the relativistic Wilson fermion in the axial magnetic field and a twisted Dirac semimetal have shown non-zero AME current density inside the bulk. However, the average AME current density vanishes in both models due to surface contributions. The AME is attributed to magnetization energy current and cannot be observed in transport experiments.

Summary: Predictions are made for the jet substructure of one-jet events produced in positron-proton neutral current deep inelastic scattering at the future Electron-Ion Collider. Data are simulated using Monte Carlo event generators and jets and subjets are produced by a cluster algorithm. The subjet multiplicity distributions and differential jet shapes are measured for different jet sizes and varying jet-resolution parameter, with a comparison between different cluster algorithms.

Summary: The NA61/SHINE experiment at CERN's SPS accelerator is being upgraded to increase the event flow rate from 80Hz to 1kHz. The upgrade involves exchanging the read-out electronics of the main tracking detectors and requires a tool for online noise filtering. A novel approach using machine learning methods is presented in this paper.

Summary: In this letter, the authors expand upon the previous work to demonstrate the entanglement observed in top quark interactions. They propose that the thermal component caused by proton collisions with top quarks emerges from entanglement within the proton wave function, and they use published results to show the expected behavior.

Summary: In this study, we investigate the near-threshold meson photoproduction from protons and nuclei and explore the possibility of observing non-strange hidden-bottom pentaquark states through differential observables. We calculate the excitation functions and energy/momentum distributions for different production processes and propose that future experiments at high-luminosity electron-ion colliders could provide evidence for the existence of these hidden-bottom pentaquark resonances.

Summary: This study presents a microscopic investigation of the electromagnetic properties of the low-lying states of single-A hypernucleus 9ABe using the HyperGCM method based on covariant density functional theory. The results are compared to those of a particle-rotor model (PRM) and show close agreement. It is found that the electric quadrupole transition strengths are more sensitive to the coupling strengths of the AN interaction than the magnetic moments and M 1 transition strengths.
