The matter created in central p+p, p+Pb and Pb+Pb collisions at root s = 5.02 TeV is simulated event-by-event using the superSONIC model, which combines pre-equilibrium flow, viscous hydrodynamic evolution and late-stage hadronic rescatterings. Employing a generalization of the Monte Carlo Glauber model where each nucleon possesses three constituent quarks, superSONIC describes the experimentally measured elliptic and triangular flow at central rapidity in all systems using a single choice for the fluid parameters, such as shear and bulk viscosities. This suggests a common hydrodynamic origin of the experimentally observed flow patterns in all high energy nuclear collisions, including p+p. (c) 2017 The Authors. Published by Elsevier B.V.

Summary: The BEST Collaboration was formed to provide a theoretical framework for analyzing data from the Beam Energy Scan program at RHIC, with the goal of searching for a QCD critical point and manifestations of the chiral magnetic effect. Progress has been made in studying the equation of state, initial state models, hydrodynamic framework, freezeout prescriptions, and hadronic transport models over the past five years, with the challenge of integrating these components into a complete analysis framework.

Hydro plus in action

Krishna Rajagopal, Gregory Ridgway, Ryan Weller, Yi Yin

Summary: The Hydro+ framework describes the interaction between hydrodynamics and out-of-equilibrium long wavelength critical fluctuations in a self-consistent manner. A simulation in a simplified model for a heavy ion collision reveals three key ingredients of critical dynamics.

Inhomogeneity of a rotating quark-gluon plasma from holography

Nelson R. F. Braga, Octavio C. Junqueira

Summary: This study investigates the influence of rotation on the transition temperature of strongly interacting matter produced in non-central heavy ion collisions. By using a holographic description of an AdS black hole, the authors extend the analysis to the more realistic case where the matter spreads over a region around the rotational axis. The results show the coexistence of confined and deconfined phases and are consistent with the concept of local temperature in rotating frames developed by Tolman and Ehrenfest.

Constrain the time variation of the gravitational constant via the propagation of gravitational waves

Bing Sun, Jiachen An, Zhoujian Cao

Summary: This paper investigates the effect of gravitational constant variation on the propagation of gravitational waves. By employing two analytical methods, the study finds that variations in the gravitational constant result in amplitude and phase corrections for gravitational waves, and the time variation of the gravitational constant can be constrained through the propagation of gravitational waves.

Quantum tunneling from Schwarzschild black hole in non-commutative gauge theory of gravity

Abdellah Touati, Zaim Slimane

Summary: This letter presents the first study of Hawking radiation as a tunneling process within the framework of non-commutative gauge theory of gravity. The non-commutative Schwarzschild black hole is reconstructed using the Seiberg-Witten map and the star product. The emission spectrum of outgoing massless particles is computed using the quantum tunneling mechanism. The results reveal pure thermal radiation in the low-frequency scenario, but a deviation from pure thermal radiation in the high-frequency scenario due to energy conservation. It is also found that noncommutativity enhances the correlations between successively emitted particles.

Compact stars: To cross or go around? That is the question

Shahar Hod

Summary: The travel times of light signals between two antipodal points on a compact star's surface are calculated for two different trajectories. It is shown that, for highly dense stars, the longer trajectory along the surface may have a shorter travel time as measured by asymptotic observers. A critical value of the dimensionless density-area parameter is determined for constant density stars to distinguish cases where crossing through the star's center or following a semi-circular trajectory on the surface has a shorter travel time as measured by asymptotic observers.
