Photons and Dileptons at LHC
Rainer J. Fries,S. Turbide,C. Gale,D. K. Srivastava
Physics , 2007,
Abstract: We discuss real and virtual photon sources in heavy ion collisions and present results for dilepton yields in Pb+Pb collisions at the LHC at intermediate and large transverse momentum p_T.
Centrality Dependence of Direct Photons in Au+Au Collisions at sqrt(s_NN) = 200 GeV
R. J. Fries,B. Muller,D. K. Srivastava
Physics , 2005, DOI: 10.1103/PhysRevC.72.041902
Abstract: We calculate the spectra of high energy photons emitted in relativistic Au+Au collisions for various centralities and compare to data recently collected at the Relativistic Heavy Ion Collider by the PHENIX collaboration. Our results for photons from primary hard scatterings and photons from interactions of jets with the medium are consistent with the measurements of neutral pion and direct photon production in p+p collisions and give a good description of direct photon spectra measured in Au+Au collisions. The contribution of photons from jet-to-photon conversion in the medium can be as large as the photon yield from hard scatterings in the momentum range p_T = 2...6 GeV/c. We show that this novel mechanism is not ruled out by any existing data.
High energy photons from passage of jets through quark gluon plasma
R. J. Fries,B. Müller,D. K. Srivastava
Physics , 2002, DOI: 10.1103/PhysRevLett.90.132301
Abstract: We calculate the production of high energy photons from Compton scattering and annihilation of a quark jet passing through a quark gluon plasma produced in a relativistic heavy ion collision. The contributions are large and reflect the momentum distribution of the jets and the initial conditions of the plasma.
Large mass dileptons from the passage of jets through quark gluon plasma
D. K. Srivastava,C. Gale,R. J. Fries
Physics , 2002, DOI: 10.1103/PhysRevC.67.034903
Abstract: We calculate the emission of large mass dileptons originating from the annihilation of quark jets passing through quark gluon plasma. Considering central collisions of heavy nuclei at SPS, RHIC and LHC energies, we find that the yield due to the jet-plasma interaction gets progressively larger as the collision energy increases. We find it to be negligible at SPS energies, of the order of the Drell-Yan contribution and much larger than the normal thermal yield at RHIC energies and up to a factor of ten larger than the Drell-Yan contribution at LHC energies. An observation of this new dilepton source would confirm the occurrence of jet-plasma interactions and of conditions suitable for jet-quenching to take place.
Inflammatory bowel disease-associated spondyloarthropathies
Walter Fries
World Journal of Gastroenterology , 2009,
Abstract: This issue presents a symposium held in Messina talking about inflammatory bowel disease (IBD) and associated spondyloarthropathies. The topic covers epidemiology and clinical manifestations of IBD-related arthropathies, common genetic and immunologic features, combined therapies for gut and joint inflammation, and future biologic therapies etc. I believe this series of articles will deeply facilitate understanding of and the approach to IBD and associated arthropathies.
