56. Photon production in the bottom-up thermalization of heavy-ion collisions

Naoto Tanji (Heidelberg University)

2/2/17, 4:00 PM

Recent classical-statistical numerical simulations have established the "bottom-up" thermalization scenario of Baier et al. as the correct weak coupling effective theory for thermalization in ultrarelativistic heavy-ion collisions. I will talk on a parametric study of photon production in the various stages of this bottom-up framework and compare the contribution of the off-equilibrium...

99. Thermal Photon Emission in Heavy Ion Collisions

Dr Axel Drees (Stony Brook University)

2/2/17, 4:25 PM

Over the past years PHENIX has published numerous results on direct photon production from Au+Au collisions at 200 GeV. The results show a large direct photon excess at low momentum, which increases with centrality, while the inverse slope of ~240 MeV remains independent of centrality within errors. The direct photons are emitted with a large anisotropy with respect to the reaction plan,...

27. Photon Puzzle at RHIC: a theory perspective

Mr Chun Shen (Brookhaven National Lab)

2/2/17, 4:50 PM

Electromagnetic probes are considered as clean messengers from the hot dense medium created in the Relativistic Heavy-Ion Collider (RHIC) and the Large Hadron Collider (LHC). In this talk, I will review the theoretical developments in the study of electromagnetic radiation in relativistic heavy-ion collisions. The recent progress in the rates for photon and lepton pair production is discussed....

45. Classical-statistical simulations and the Chiral Magnetic Effect

Mr Niklas Mueller (Institute for Theoretical Physics, Heidelberg University)

2/2/17, 5:15 PM

We present how the dynamics of the Chiral Magnetic Effect (CME) and Chiral Density Waves can be described during the pre-equilibrium stage of a heavy-ion collision, using classical-statistical real-time lattice simulations [1-3]. To this end we present results in a simplified set-up with dynamical (Wilson and Overlap) fermions simultaneously coupled to color and electro-magnetic fields. We...
