Parallel 23: heavy quarkonia production
- Enrico Scomparin (INFN Torino (IT))
The substantial masses of charm hadrons make them exceptional tools for the study of quantum chromodynamics (QCD), providing quantitative insights into QCD dynamics for systems having high parton densities and/or temperatures. Final-state effects, including interactions with co-moving particles or quark coalescence, may modify the hadronization of heavy quarks. To study these effects, we...
A number of new four-quark states containing from one to four $c$ or $\overline c$ quarks have been observed recently. Many of these new states have been discovered at the LHC. The production of these states via intrinsic charm in the proton is investigated. The tetraquark masses obtained in this approach, agree well with the measured masses. These calculations can provide some insight into...
The interaction between the nucleon and charmonia ($J/\psi$ and $\eta_c$) is expected to deepen our understanding of various aspects in nonperturbative QCD ranging from the origin of nucleon mass to $J/\psi$ suppression in heavy-ion collisions and properties of hidden-charm pentaquark states. Here, we present the first lattice QCD studies on low-energy $NJ/\psi$ and $N\eta_c$ interactions...
