Prediction of a photon peak in heavy ion collisions

Casalderrey Solana, JorgeMateos, David (Mateos Solé)2010-07-052010-07-0520090031-9007https://hdl.handle.net/2445/13295We show that if a flavorless vector meson remains bound after deconfinement, and if its limiting velocity in the quark-gluon plasma is subluminal, then this meson produces a distinct peak in the spectrum of thermal photons emitted by the plasma. We also demonstrate that this effect is a universal property of all strongly coupled, large- N c plasmas with a gravity dual. For the J / ψ , the corresponding peak lies between 3 and 5 GeV and could be observed in heavy-ion collisions at the LHC.4 p.application/pdfeng(c) American Physical Society, 2009Reaccions nuclearsTeoria de camps (Física)Partícules (Física nuclear)Nuclear reactionsField theory (Physics)Particles (Nuclear physics)Prediction of a photon peak in heavy ion collisionsinfo:eu-repo/semantics/article562526info:eu-repo/semantics/openAccess
