Abstract

We provide predictions for the rapidity distributions of exclusive photoproduced J/{psi} and {upsilon} mesons, and Z{sup 0} bosons, at the Tevatron and Large Hadron Collider. We use the equivalent-photon approximation with the photon-proton cross sections given by the impact parameter dependent dipole saturation model, which has already been shown to give a good description of a wide variety of HERA data. We derive the quark-antiquark light-cone wave functions of timelike neutral electroweak bosons. An essential difference is pointed out between the amplitude for timelike heavy boson photoproduction and the amplitude for deeply virtual Compton scattering.

Exclusive diffractive processes at HERA within the dipole picture

Journal Article Kowalski, H ; Motyka, L ; Institute of Physics, Jagellonian University, 30-059 Cracow ; ... - Physical Review. D, Particles Fields

We present a simultaneous analysis, within an impact parameter dependent saturated dipole model, of exclusive diffractive vector meson (J/{psi}, {phi}, and {rho}) production, deeply virtual Compton scattering and the total {gamma}*p cross section data measured at HERA. Various cross sections measured as a function of the kinematic variables Q{sup 2}, W and t are well described, with little sensitivity to the details of the vector meson wave functions. We determine the properties of the gluon density in the proton in both longitudinal and transverse dimensions, including the impact parameter dependent saturation scale. The overall success of the description indicates universalitymore »« less

Exclusive production of vector mesons in pp and pp-bar collisions

Journal Article Cisek, Anna ; Schaefer, Wolfgang ; Szczurek, Antoni ; ... - AIP Conference Proceedings

Protons and antiprotons at collider energies are a source of high energy Weizsaecker-Williams photons. This opens up a possibility to study at the LHC exclusive photoproduction of heavy vector mesons at energies much larger than possible at the HERA accelerator.We present selected results on the production of vector mesons {rho}, {omega}, {phi}, J/{Psi} and {Upsilon}. We show distributions in rapidity, transverse momentum of mesons and azimuthal angle between outgoing protons for RHIC, Tevatron and LHC energies. The absorption effects are discussed.The amplitude for {gamma}p{yields}Vp is calculated in a pQCD k{sub T}-factorization approach with an unintegrated gluon distribution constrained by inclusivemore »« less

QCD corrections to polarization of J/{psi} and {upsilon} at Fermilab Tevatron and CERN LHC

Journal Article Bin, Gong ; Jianxiong, Wang - Physical Review. D, Particles Fields

In this work, we present more details of the calculation on the next-to-leading-order (NLO) QCD corrections to polarization of direct J/{psi} production via color singlet at the Tevatron and LHC, together with the results for {upsilon} for the first time. Our results show that the J/{psi} polarization status drastically changes from transverse polarization dominant at leading order into longitudinal polarization dominant in the whole range of the transverse momentum p{sub t} of J/{psi} when the NLO corrections are counted. For {upsilon} production, the p{sub t} distribution of the polarization status behaves almost the same as that for J/{psi} except thatmore »« less

Can one measure timelike Compton scattering at LHC?

Journal Article Pire, B ; Szymanowski, L ; Wagner, J - Physical Review. D, Particles Fields

Exclusive photoproduction of dileptons, {gamma}N{yields}l{sup +}l{sup -}N, is and will be measured in ultraperipheral collisions at hadron colliders, such as the Tevatron, Relativistic Heavy Ion Collider, and the LHC. We demonstrate that the timelike deeply virtual Compton scattering mechanism {gamma}q{yields}l{sup +}l{sup -}q where the lepton pair comes from the subprocess {gamma}q{yields}{gamma}*q dominates in some accessible kinematical regions, thus opening a new way to study generalized parton distributions in the nucleon. High energy kinematics enables one to probe parton distributions at small skewedness. This subprocess interferes at the amplitude level with the pure QED subprocess {gamma}{gamma}*{yields}l{sup +}l{sup -} where the virtualmore » photon is radiated from the nucleon.« less

Complementarity of the CERN LEP collider, the Fermilab Tevatron, and the CERN LHC in the search for a light MSSM Higgs boson

Journal Article Carena, M ; Mrenna, S ; Wagner, C E. M. - Physical Review. D, Particles Fields

We study the discovery potential of the CERN LHC, Fermilab Tevatron and CERN LEP colliders in the search for the neutral CP-even Higgs boson of the MSSM which couples to the weak gauge bosons with a strength close to the standard model one and, hence, plays a relevant role in the mechanism of electroweak symmetry breaking. We place special emphasis on the radiative effects which influence the discovery reach of these colliders. We concentrate on the Vbb(bar sign) channel, with V=Z or W, and on the channels with diphoton final states, which are the dominant ones for the search formore »« less
