Quarkonium+γ production in coherent hadron–hadron interactions at LHC energies
نویسندگان
چکیده
In this paper we study the H + γ (H = J/Ψ and Υ ) production in coherent hadron–hadron interactions at LHC energies. Considering the ultrarelativistic protons as a source of photons, we estimate the γ + p →H + γ +X cross section using the non-relativistic QCD (NRQCD) factorization formalism and considering different sets of values for the matrix elements. Our results for the total p + p → p +H + γ +X cross sections and rapidity distributions at √ s = 7 and 14 TeV demonstrate that the experimental analysis of the J/Ψ + γ production at LHC is feasible.

Suppression of Quarkonium Production in Heavy Ion Collisions at RHIC and LHC
A model for the production of quarkonium states in the midrapidity region at RHIC and LHC energy range is presented which explores well understood properties of QCD only. An increase of the quarkonium hadronisation time with the initial energy leads to a gradual change of the most important phenomena from fixed targetto collider-energies. We evaluate nuclear effects in the quarkonium production...
متن کاملHard diffractive quarkonium hadroproduction at high energies
We present a study of heavy quarkonium production in hard diffractive processes by pomeron exchange for Tevatron and LHC energies. The numerical results are computed using a recent experimental determination of the diffractive parton density functions in the pomeron and these are corrected by unitarity corrections through the gap survival probability factor. We give predictions for single as we...
متن کاملBi-tp 63/94 Quarkonium Production in Hadronic Collisions
We summarize the theoretical description of charmonium and bottonium production in hadronic collisions and compare it to the available data from hadron-nucleon interactions. With the parameters of the theory established by these data, we obtain predictions for quarkonium production at RHIC and LHC energies. To appear in Hard Processes in Hadronic Interactions H.

متن کاملUltra-peripheral collisions and hadronic structure
Ultra-peripheral collisions are the energy frontier for photon-mediated interactions, reaching, at the Large Hadron Collider (LHC), γ− p center of mass energies five to ten times higher than at HERA and reaching γγ energies higher than at LEP. Photoproduction of heavy quarkonium and dijets in pp and pA collisions probes the gluon distribution in protons at Bjorken-x values down to 3 × 10−6, far...
متن کاملCapabilities of the CMS detector for studies of hard probes in heavy ion collisions at the LHC
The capabilities of the CMS experiment to study properties of hot and dense QCD-matter created in heavy ion collisions at the CERN Large Hadron Collider with the perturbative processes (socalled ”hard probes”) are presented. Detailed studies from complete simulations of the CMS detectors in Pb+Pb collisions at √ s = 5.5 TeV per nucleon pair are presented in view of two hard probes: quarkonium a...
