Title: Fragmentation contributions to $J / ψ$ photoproduction at HERA

Abstract

Here, we compute leading-power fragmentation corrections to J/ψ photoproduction at DESY HERA, making use of the nonrelativistic QCD factorization approach. Our calculations include parton production cross sections through order α³_s, fragmentation functions though order α²_s, and leading logarithms of the transverse momentum divided by the charm-quark mass to all orders in α_s. We find that the leading-power fragmentation corrections, beyond those that are included through next-to-leading order in α_s, are small relative to the fixed-order contributions through next-to-leading order in α_s. Consequently, an important discrepancy remains between the experimental measurements of the J/ψ photoproduction cross section and predictions that make use of nonrelativistic-QCD long-distance matrix elements that are extracted from the J/ψ hadroproduction cross-section and polarization data.

Nucleon dissociation and incoherent $J / ψ$ photoproduction on nuclei in ion ultraperipheral collisions at the CERN Large Hadron Collider

Journal Article Guzey, V. ; Strikman, M. ; Zhalov, M. - Physical Review. C

Using the general notion of cross section fluctuations in hadron-nucleus scattering at high energies, we derive an expression for the cross section of incoherent J/ψ photoproduction on heavy nuclei dσ_{γA → J/ψY} /dt, which includes both elastic dσ_{γ → Jψp}/ dt and proton-dissociation dσ_{γp → J/ψY} /dt photoproduction on target nucleons. We find that, with good accuracy, dσ_{γA → J/ψY} /dt can be expressed as a product of the sum of the dσ_{γp → J/ψp} /dt and dσ_{γp → J/ψY} /dt cross sections, which have been measured at HERA, and the common nuclear shadowing factor, which is calculated usingmore »« less

Reconciling J/{psi} Production at HERA, RHIC, Tevatron, and LHC with Nonrelativistic QCD Factorization at Next-to-Leading Order

Journal Article Butenschoen, Mathias ; Kniehl, Bernd A - Physical Review Letters

We calculate the cross section of inclusive direct J/{psi} hadroproduction at next-to-leading order within the factorization formalism of nonrelativistic quantum chromodynamics, including the full relativistic corrections due to the intermediate {sup 1}S{sub 0}{sup [8]}, {sup 3}S{sub 1}{sup [8]}, and {sup 3}P{sub J}{sup [8]} color-octet states. We perform a combined fit of the color-octet long-distance matrix elements to the transverse-momentum (p{sub T}) distributions measured by CDF at the Fermilab Tevatron and H1 at DESY HERA and demonstrate that they also successfully describe the p{sub T} distributions from PHENIX at BNL RHIC and CMS at the CERN LHC as well as themore »« less

$ψ^{(*)} p$ scattering length based on near-threshold charmonium photoproduction

Journal Article Wang, Xiao-Yun ; Zeng, Fancong ; Strakovsky, Igor I. - Physical Review C

Under the framework of vector meson dominance model, the value of scattering length can be expressed as a function of the ratio between total cross section σ(W) and R(W), where R(W) is the ratio between final momentum |p₃| and initial momentum |p₁| and positively correlated with the center-of-mass energy. Based on the theoretical study of charmonium's photoproduction within two gluon exchange model and effective Pomeron model, we research the scattering lengths of vector mesons and proton interaction in this work. Results show that the scattering length |α_J/ψp| obtained from the two models are close and basically in agreement with themore »« less
