Prediction of a missing higher charmonium around 4.26 GeV in family
Inspired by the similarity of mass gaps of and families,
the prediction of missing higher charmonium with mass MeV and very
narrow width is made. In addition, the properties of two charmonium-like
states, and , and charmonium are discussed.
Here, as is established while the explanation of
to be is fully excluded and is typically a
very narrow state. These predictions can be accessible at BESIII, Belle and
BelleII in near future.Comment: 5 pages, 5 figures and 1 table. More discussions added. Accepted by

Production of large transverse momentum dileptons and photons in , and collisions by photoproduction processes
The production of large dileptons and photons originating from
photoproduction processes in , and collisions is calculated. We
find that the contribution of dileptons and photons produced by photoproduction
processes is not prominent at RHIC energies. However, the numerical results
indicate that the modification of photoproduction processes becomes evident in
the large region for , and collisions at LHC energies.Comment: 10 figure
