Ultra-peripheral collisions of relativistic heavy ions
We report the first observation of exclusive ρ production in ultra-peripheral collisions at RHIC. The ρ are produced electromagnetically at large impact parameters where no hadronic interactions occur. The produced ρ have a small perpendicular momentum, consistent with production that is coherent on both the photon emitting and scattering nuclei. We observe both exclusive ρ production, and ρ pr...
متن کاملProduction of Anticentauro Events in Ultra-relativistic Heavy Ion Collisions
We propose a novel method for studying the production of anticentauro events in high energy heavy ion collisions utilizing Chebyshev expansion coefficients. These coefficients have proved to be very efficient in investigating the pattern of fluctuations in neutral pion fraction. For the anticentauro like events, the magnitude of first few coefficients is strongly enhanced (≈3 times) as compared...
متن کاملBremsstrahlung Dileptons in Ultra-relativistic Heavy Ion Collisions
We consider production of dilepton pairs through coherent electro-magnetic radiation during nuclear collisions. We show that the number of pairs produced through bremsstrahlung is about two orders of magnitude smaller than the yield measured by the CERES collaboration. Therefore, coherent bremsstrahlung can be ruled out as an explanation for the observed enhancement of low mass dileptons in CER...
متن کامل0 Photons from Ultra - Relativistic Heavy Ion Collisions
It is believed that a novel state of matter Quark Gluon Plasma (QGP) will be transiently produced if normal hadronic matter is subjected to sufficiently high temperature and/or density. We have investigated the possibility of QGP formation in the ultra-relativistic collisions of heavy ions through the electromagnetic probes photons and dileptons. The formulation of the real and virtual photon p...
