Charmonium Production in 920 GeV Proton-Nucleus Interactions
Using data collected by the HERA-B experiment in the short commissioning run in the year 2000, we have studied the charmonium production in... -

Pion PDFs confronted by fixed-target charmonium production
The pion, as the Goldstone boson of the strong interaction, is the lightest QCD bound state and responsible for the long-range nucleon-nucleon...

Pion and photon beam initiated backward charmonium or lepton pair production
Hard exclusive reactions initiated by pion or photon beams within the near-backward kinematical regime specified by the small Mandelstam variable

Study of Charmonium Production in \({e^{+}e^{-}}\) Annihilation above \(\sqrt{{s}}{=3.81}\) GeV
AbstractThe recent results on charmonium production at BESIII are reviewed, including the observation of charmonium-like states in the processes of...

Strong decays of charmonium-like state Y(4230)
Strong decays of the charmonium-like state Y (4320) have been studied in the framework of the covariant confined quark model. The resonance Y has been...

Search for the double-charmonium state with ηcJ/ψ at Belle
We measure the cross section of e + e − → η c J/ψ at the Υ( nS )( n = 1–5) on-resonance and 10.52 GeV off-resonance energy points using the full data sample...

Study of charmonium and charmonium-like contributions in B+ → J/ψηK+ decays
A study of B + → J / ψηK + decays, followed by J / ψ → μ + μ − and η → γγ, is performed using a dataset collected with the LHCb detector in proton-proton...

Charmonium suppression in ultra-relativistic proton–proton collisions at LHC energies: a hint for QGP in small systems
Proton–proton ( pp ) collision has been considered as a baseline to study the system produced in relativistic heavy-ion (AA) collisions with the basic...

Study of exclusive photoproduction of charmonium in ultra-peripheral lead-lead collisions
The cross-sections of exclusive (coherent) photoproduction J/ψ and ψ (2S) mesons in ultra-peripheral PbPb collisions at a nucleon-nucleon...

Exotic Charmonium-Like States at BESIII
The BESIII experiment at the Bei**g Electron Positron Collider (BEPCII) collected large data samples for electron-positron collisions with...

Next-to-leading-order QCD corrections to a vector bottomonium radiative decay into a charmonium
Within the framework of nonrelativistic QCD (NRQCD) factorization, we calculate the next-to-leading-order (NLO) perturbative corrections to the...
