Production of exotic hadrons at hadron colliders
The observation of many unexpected states decaying into heavy quarkonia has challenged the usual QQ̄ interpretation. One of the most studied exotic states, the X(3872), happens to be copiously produced in high-energy hadron collisions. We discuss how this large prompt production cross-section disfavors a loosely-bound molecule interpretation for this particle. This is supported by Monte Carlo si...
متن کاملExotic hadrons from quark clustering at FAIR
The CBM experiment at FAIR will probe nuclear matter at high densities and comparatively low temperatures, giving access to a region of the phase diagram of QCD not yet studied in detail. One expects to find highly compressed hadronic matter and, at higher energies, deconfined quark matter, possibly subject to strong correlations. These conditions could be favourable to the production of exotic...
متن کاملNew Heavy Exotic Hadrons
We review recent studies on exotic states at the Belle experiment. The results include: (1) The measurement of the cross sections of γγ → ωφ , φφ , and ωω for masses that range from threshold to 4.0 GeV. In addition to signals from well established spin-zero and spin-two charmonium states, there are clear resonant structures below charmonium threshold, which have not been previously observed. W...
متن کاملExotic Hadrons in Constituent Models
Thèse présentée pour l'obtention du grade légal de Docteur en Sciences Directeur de thèse : D r Claude Semay Membres du jury : Remerciements Bientôt 4 ans depuis mon arrivéè a l'université de Mons-Hainaut, la thèse se termine et une page se tourne. L'entrée dans l'univers de la recherche n'est pas une tâche aisée et cette aventure, loin d'ˆ etre terminée (je l'espère !), n'aurait pas commencé s...
متن کاملQCD Coulomb Gauge Approach to Exotic Hadrons
The Coulomb gauge Hamiltonian model is used to calculate masses for selected J states consisting of exotic combinations of quarks and gluons: ggg glueballs (oddballs), qq̄g hybrid mesons and qq̄qq̄ tetraquark systems. An odderon Regge trajectory is computed for the J−− glueballs with intercept much smaller than the pomeron, explaining its nonobservation. The lowest 1 hybrid meson mass is found to ...
