37. Detection feasibility evaluation of ultra-intense magnetic field with dimuons at ALICE in Runs 2 and 3

Kento Kimura for the ALICE collaboration (Hiroshima University (JP))

Experiment

High energy heavy ion collisions at the LHC generate extreme magnetic field reaching $10^{14}$ T~$10^{15}$ T when heavy ions cross each other at almost the speed of light in peripheral collisions. The intensity of this generated magnetic field is much higher than the critical magnetic field of electrons, $4×10^9$ T, and various nonlinear behaviors such as real photon decay are expected in the...

87. Renormalization of equation of state by hydrodynamic fluctuations within dynamical model

Dr Koichi Murase (Kyoto University)

06/11/2021, 16:17

Theory

Event-by-event fluctuations measured in the heavy-ion observables such as the flow coefficients and their correlations play an important role in extracting the matter properties. While the major origin of the observed flows are the initial fluctuations, other sources of the fluctuations become also important in smaller systems and in the quantitative determination of the matter...

62. The coupled approach to solving the RAA-v2 puzzle in high-energy heavy-ion collisions

Wenbin Zhao (Central China Normal University)

06/11/2021, 16:34

Theory

Hydrodynamic expansion and jet quenching are responsible for the production of low and high transverse-momentum ($p_T$) particle in heavy-ion collisions, respectively. However, it is still a challenge to simultaneously describe hadron nuclear modification factor RAA and elliptic flow $v_2$, especially in the intermediate pT region of 2<$p_T$<10 GeV/c. In this talk, besides hydrodynamics and...

12. Interplay between core and corona components from p--p to Pb--Pb collisions at LHC energies

Yuuka Kanakubo (Sophia Univ.)

06/11/2021, 16:51

Theory

Hydrodynamics-based frameworks have been developed as powerful tools to extract properties of the quark-gluon plasma (QGP) from experimental data of relativistic heavy-ion collisions at RHIC and LHC. Although significant developments have been made so far, hydrodynamics-based frameworks still have open issues to be resolved. First, energy and momentum of incoming nuclei are not respected in...

11. Suppressed flow harmonics: A signature of the QCD critical point?

Mr Md Hasanujjaman (Darjeeling Govt. College)

06/11/2021, 17:08

Experiment

The fate of a perturbation (disturbance) imparted in the QGP fluid governed by the second-order Israel-Stewart viscous hydrodynamics has been studied when it passed through the Critical End Point (CEP). The effects of CEP have been incorporated in the system through the Equation of State (EoS). The dispersion relation for the perturbation in frequency ($\omega$) wave vector ($k$) space has...

19. Light nuclei production and QCD critical point

Shanjin Wu (Peking University)

06/11/2021, 17:25

Theory

Light-nuclei production is one of the hot topics in heavy-ion collisions for the high-baryon-density region of the QCD phase diagram. It was found to exhibit a non-monotonic behavior with respect to the colliding energy in experiments and thus was suggested to be a possible signal of the QCD critical point.

This talk introduces a systematic expansion of the light-nuclei production within...

173. Characterizing the initial conditions of ultra-relativistic heavy-ion collisions at the LHC

You Zhou (Niels Bohr Institute (DK))

06/11/2021, 17:42

The primary goal of the ultrarelativistic heavy-ion collision program at the LHC is to study the quark-gluon plasma (QGP) properties, a state of strongly interacting matter that exists at high temperatures and energy densities. However, the lack of knowledge on the initial conditions of heavy-ion collision results in a significant uncertainty of the extraction of the transport properties of...
