28. Anomalous Hall instability in chiral magnetohydrodynamics

Shuai Wang (Fudan University)

Poster

The quark gluon plasma(QGP) is expected to exhibit a chiral imbalance known as the chiral anomaly which induces various anomalous currents, such as: the chiral magnetic effect(CME), the chiral vortical effect(CVE) , the anomalous Hall effect(AHE) and so on. To describe these anomalous effects, one can use the chiral magnetohydrodynamics (CMHD).

We study the collective excitations and...

18. Chiral symmetry for an accelerated and rotated observer

Zhibin Zhu

Poster

In the relativistic heavy ion collision experiment, there exist a large acceleration and rapid rotation in the non-central collision which can be considered as a system with acceleration and rotation. According to the Hawking-Unruh effect, the accelerated observer sees himself in a system with Unruh temperature $T/2\pi$. And the color glass condensate picture predicts that in heavy ion...

23. Dilepton production rates from charged pion-pair annihilations on inhomogeneous chiral condensates

Kentaro Hayashi (Kochi University)

Poster

In the context of study of QCD phase diagram, the possibility of inhomogeneous chiral condensed phase in low-temperature and high-density regions has been discussed using the low-energy effective theory of QCD such as the Ginzburg-Landau theory, the Nambu-Jona-Lasinio model and so forth. It has also been pointed out that the dispersion relations of Nambu-Goldstone bosons may change in this...

30. Dissociation Reactions of Large-p_T Charmonia

Dr Yihao Pan (Jiangxi University of Science and Technology)

Poster

In this talk I will discuss dissociation of large-momentum charmonia with light mesons in hadronic matter. Momenta of charmonia created in Pb-Pb collisions at the CERN Large Hadron Collider are so large that three or more mesons may be produced when the charmonia collide with light mesons in hadronic matter. We study the meson-charmonium collision in a mechanism where the collision produces...

32. Fierz-complete four-quark interactions within fRG-QCD

Zining Wang (Dalian University of Technology)

Poster

This work is based on 2+1 flavor quantum chromodynamics (QCD) calculations
within the functional renormalization group (fRG) approach. We calculate the four-fermi interaction of QCD under the Fierz-complete basis, and improve the flow equations of dynamical hadronization. We also calculate the contributions of different four-fermi channels under finite temperature and density, split the...

10. Heavy quark dynamics via Gribov-Zwanziger approach

Mr SUMIT Rana (IIT Roorkee)

Poster

We investigate the momentum-dependent drag and diffusion coefficient of heavy quarks (HQs) moving in the quark-gluon plasma (QGP) background. The leading order scattering amplitudes required for this purpose have been obtained using the Gribov-Zwanziger propagator for the mediator gluons to incorporate the non-perturbative effects relevant to the phenomenologically accessible temperature...

45. Lee-Yang edge singularities in QCD via the Dyson-Schwinger Equations

Ziyan Wan (Peking University)

Poster

We take the Dyson-Schwinger Equation approach of QCD for the quark propagator at complex chemical potential to study the QCD phase transition. The phase transition line of the (2+1) flavor QCD matter in the imaginary chemical potential region is computed via a simplified truncation scheme, which curvature is found to be consistent with the one at real chemical potential. Moreover, the...

35. One-pion exchange potential in a strong magnetic field

Daiki Miura (Niigata University)

Poster

The properties of QCD matter in a strong magnetic field have attracted much attention because of their relevance to the physics of relativistic heavy-ion collisions and magnetars. For example, the effects of magnetic fields are intensely studied in both single-body and many-body problems, such as modifications of the hadron mass spectrum and the QCD phase diagram. On the other hand, recent...

44. Pseudoscalar Screening Mass at Finite Temperature and Magnetic Field

rishabh thakkar

Poster

We present lattice QCD results on the screening mass of pseudoscalar mesons at finite temperatures and nonzero magnetic fields. The results, which have been continuum extrapolated, are based on (2+1)-flavor lattice QCD simulations at the physical point using the HISQ/tree action, with a lattice temporal extent ranging from 8 to 16. The investigated temperature range is near the pseudocritical...

34. Rotational effect of J/ψ particle dissociation

Liang Yuhao

Poster

ALICE collaboration observed the spin polarization of J/ψ particles with respect to the event plane, finding less particles in the spin zero states. A possible explanation is the spin dependent dissociations of prompt J/psi in the quark-gluon plasma. we consider the effect of vorticity on the dissociation rate in the dominant inelastic scattering process. Using quark and gluon propagators from...

22. Spin-alignment of J/ψ meson: Dissociation mechanism of magnetic interaction

Zhishun Chen (SYSU)

Poster

Recently, ALICE first measured the spin polarization of the J/ψ with respect to the event plane. To explain the experiment, we considered a possible mechanism for the spin alignment of J/ψ —— gluon dissociation, in which flow induce spin alignment. This spin dependent process contains chromo-magnetic coupling between J/ψ and gluon, and the dissociation rate may contribute to the spin alignment.

37. Universal Love-C relation for hybrid stars with crystalline quark core

Zhiyuan Dong (Central China Normal University)

Poster

The extreme conditions within neutron stars provide a unique laboratory for probing QCD phases, like the crystalline colour superconducting (CCS) phase. We investigate the observable properties of hybrid stars (HSs) with a solid quark matter core in the CCS phase. These HS models are characterized by a sharp phase transition with a significant density discontinuity, which softens the equations...
