Neutron unbound states in ^{23}N were populated via proton knockout from an 83.4 MeV/nucleon ^{24}O beam on a liquid deuterium target. The two-body decay energy displays two peaks at E_{1}∼100keV and E_{2}∼1MeV with respect to the neutron separation energy. The data are consistent with shell model c…

Full jet in quark-gluon plasma with hydrodynamic medium response

Author(s): Yasuki Tachibana, Ning-Bo Chang, and Guang-You Qin
The authors develop a coupled jet-fluid model that includes interactions between jets and a fluid medium in a heavy-ion collision. The model treats both the effect of the medium on the jet shower as well as the back-reaction of this energy deposition on the medium itself. The authors show how the energy that is lost by a jet is deposited in and evolves with the medium, and how that deposited energy might appear in measured observables.

The stiff equation of state (EoS) giving the neutron-star mass of 2M_{⊙} suggests the existence of strongly repulsive many-body effects (MBE) not only in nucleon channels but also in hyperonic ones. As a specific model for MBE, the repulsive multi-Pomeron exchange potential (MPP) is added to the two…
