Abstract

The J/{Psi}-meson dissociation in nuclear matter remains one of the most surprising problems in physics. In 2000 the NA50 Collaboration at CERN reported anomalous results on J/{Psi} absorption that was considered as evidence of Quark-Gluon Plasma formation. On the other hand, there may be other mechanisms which produce an increase in J/{Psi} absorption in a hot dense medium due to the modification of the charm mesons. Our detailed calculations were one of the first indications that the CERN data can indeed be well explained by a mechanism different from QGP formation. For further clarification we proposed to study the modification of charm in nuclei through antiproton annihilation, which is now part of the PANDA project at FAIR GSI. The experiment on charmonium dissociation in nuclei is under discussion at JLab as part of its 12 GeV upgrade.

Charmonium dissociation in matter: perspectives from CERN to Jlab

Conference Sibirtsev, A - AIP Conference Proceedings: Achievements And New Directions In Subatomic Physics: Workshop In Honour Of Tony Thomas' 60th Birthday

The J/Psi-meson dissociation in nuclear matter remains one of the most surprising problems in physics. In 2000 the NA50 Collaboration at CERN reported anomalous results on J/Psi absorption that was considered as evidence of Quark-Gluon Plasma formation. On the other hand, there may be other mechanisms which produce an increase in J/Psi absorption in a hot dense medium due to the modification of the charm mesons. Our detailed calculations were one of the first indications that the CERN data can indeed be well explained by a mechanism different from QGP formation.

D mesons and charmonium states in asymmetric nuclear matter at finite temperatures

Journal Article Kumar, Arvind; Mishra, Amruta - Physical Review. C, Nuclear Physics

We investigate the in-medium masses of D and D-bar mesons in the isospin-asymmetric nuclear matter at finite temperatures arising due to the interactions with the nucleons, the scalar-isoscalar meson sigma, and the scalar-isovector meson delta within a SU(4) model. However, since the chiral symmetry is explicitly broken for the SU(4) case due to the large charm quark mass, we use the SU(4) symmetry here only to obtain the interactions of the D and D-bar mesons with the light hadron sector but use the observed values of the heavy hadron masses and empirical values of the decay constants. The in-medium massesmore »« less

Charmonium production in fixed-target experiments with SPS and LHC beams at CERN

Journal Article Kurepin, A; Golubeva, M - Physics of Atomic Nuclei

The possibility of measuring cross sections for the production of J/{psi} mesons in fixed-target experiments with the proton and ion beams of the Large Hadron Collider (LHC) at CERN (Switzerland) is considered. At the present time, measurements of charmonium production in proton-proton collisions at an energy of 7 TeV have begun at LHC. Previously, the production of J/{psi} and {psi} Prime mesons was studied in the NA38, NA50, and NA60 fixed-target experiments with beams of the CERN synchrotron (SPS) and in the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC, Brookhaven National Laboratory, USA). A normal nuclear absorption ofmore »« less

Charmonium production in proton-proton collisions and in collisions of lead nuclei at CERN and comparison with Brookhaven data

Journal Article

A review of experimental data on charmoniumproduction that were obtained in fixed-target experiments at the SPS synchrotron and in proton-proton collisions and in collisions of lead nuclei in beams of the Large Hadron Collider (LHC) at CERN (Switzerland) is presented. A comparison with data obtained at the Brookhaven National Laboratory (USA) from experiments at the Relativistic Heavy Ion Collider (RHIC) is performed. Measurement of the suppression of J/{psi}-meson production as a possible signal of the production of quark-gluon plasmawas proposed back in 1986 by T. Matsui and H. Satz. An anomalous suppression of J/{psi}-meson production was discovered by the NA50more »« less

{ital J}/{psi} suppression in heavy ion collisions at the CERN Super Proton Synchrotron

Journal Article Kahana, D; Kahana, S - Physical Review, C

We reexamine the production of J/{psi} and other charmonium states for a variety of target-projectile choices at the CERN Super Proton Synchrotron, in particular for the interesting comparison between S+U at 200 GeV/c and Pb+Pb at 158 GeV/c as observed in the experiments NA38 and NA50, respectively. For this study we use a newly constructed cascade code LUCIFER II, which yields acceptable descriptions of both hard and soft processes, specifically Drell-Yan and meson production. This code divides the ion-ion collision into an initial phase involving hard interactions of the original nucleons and no soft energy loss, followed after the mesonmore »« less
