Charm Photoproduction At Large Transverse Momentum And The Charm Content Of The Photon [PDF]
, 1995 The charm quark photoproduction at large transverse momentum in the resolved photon interaction via partonic subprocess $\cg$ is studied. It is shown that at HERA energies the contribution of the charm quark excitation in the photon in the inclusive ...

Update on Partial-Wave Analysis
, 2001 Partial-wave analysis is one step in a process connecting experimental measurements to the N* states we are studying. Progress has been made in the area of `model-independent' analysis. However, more model-dependent approaches are needed to cover broader

Photoproduction models for total cross section and shower development
EPJ Web of Conferences, 2015 A model for the total photoproduction cross section, based on the ansatz that resummation of infrared gluons limits the rise induced by QCD minijets in all the total cross-sections, is used to simulate extended air showers initiated by cosmic rays with ...

Diffractive photoproduction of ηc [PDF]
Nuclear Physics A, 2003 Diffractive photoproduction of $ _c$ is an important process to study the effect of Odderon, whose existence is still not confirmed in experiment. A detailed interpretation of Odderon in QCD, i.e., in terms of gluons is also unclear.Taking charm quarks as heavy quarks, we can use NRQCD and take $ _c$ as a $c\bar c$ bound state.

Diffraction and ultraperipheral collisions at ALICE
, 2013 The ALICE experiment measured J/psi photoproduction in Pb+Pb ultraperipheral collisions at sqrt(s_NN) = 2.76 TeV at forward and central rapidity. The coherent J/psi cross section is found to be in good agreement with those models which include nuclear ...

EPJ Web of Conferences, 2016 In this talk we present preliminary experimental results of Dalitz plot analysis of the decay η′ → η π+ π−, based on the CLAS data collected during photoproduction experiment γ p → η′ p for the center-of-mass energy from 1.90 to 2.62 GeV at Jefferson Lab.

Angular Dependence of η Photoproduction in Photon-Induced Reaction
Advances in High Energy Physics, 2018 Photoproduction of η mesons from nucleons can provide valuable information about the excitation spectrum of the nucleons. The angular dependence of η photoproduction in the photon-induced reaction is investigated in the multisource thermal model.

EPJ Web of Conferences, 2014 We discuss the CMS capabilities of measuring vector mesons in pp and heavyion collisions based on the recent results of the exclusive dilepton and diboson production. Studies evaluating the detection of exclusive J/ψ and ϒ vector meson photoproduction in

Photon-hadron and photon-photon collisions in ALICE
, 2015 A review is given on photon-hadron and photon-photon collisions in the ALICE experiment. The physics motivation for studying such reactions is outlined, and the results obtained in proton-lead and lead-lead collisions in Run 1 of the LHC are discussed ...

Ultra-peripheral heavy-ion collisions with the CMS experiment
EPJ Web of Conferences, 2017 Ultraperipheral collisions (UPCs) of heavy ions involve long range electromagnetic interactions at impact parameters larger than sum of their radii where hadronic interaction is largely suppressed and the exchanged photon materializes into qq(bar) bound ...
