Coherent Final State Interaction in Jet Production in Nucleus-nucleus Collisions
We study the coherent final state interaction of an energetic parton produced in AA collisions caused by the change in the cutoff scale and running coupling constant from the vacuum to QGP. We demonstrate that the contribution of this new mechanism to the energy loss may be of the order of magnitude of the induced gluon radiation. However, an accurate evaluation of this medium effect is a diffi...
متن کاملCoherent pion production in neutrino-nucleus collisions
We have investigated the neutrino induced coherent pion production reaction at low and intermediate energies including pion, nucleon and ∆(1232) resonance. Medium effects in the production mechanism and the distortion of the pion wave function are included in the calculation. We find a strong reduction of the cross section due to these effects and also substantial modifications in the energy di...
متن کاملCoherent Interactions in Nucleus- Nucleus Collisions
At the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory and at the Large Hadron Collider (LHC) at CERN, particles will be produced in coherent and diffractive nuclear interactions. In extremely peripheral nuclear collisions (b>2R), coherent interactions occur at very high rates and are dominated by photonPomeron or photon-meson processes. In these reactions, the photon a...
متن کاملSubthreshold antiproton production in nucleus-nucleus collisions.
Antiproton production from the secondary process pp~ pp is studied for nucleus-nucleus collisions at energies which are below the threshold for its production from the nucleon-nucleon reaction in the free space. In an expanding fireball model, we determine the p abundance from the fusion of pions and find that for collisions at 2. 1 GeV/nucleon the antiproton to negative pion ratio is = 5.5&10 ...
متن کاملcharm production in relativistic nucleus - nucleus collisions ∗
We calculate excitation functions for open charm mesons in Au + Au reactions from AGS to RHIC energies within the HSD transport approach which is based on string, quark, diquark (q, ¯ q, qq, ¯ q ¯ q) and hadronic degrees of freedom. The open charm cross sections from pN and πN reactions are fitted to results from PYTHIA and scaled in magnitude to the available experimental data. From our dynami...
