The Role of Produced Hadrons in J/psi Suppression

Cheuk-Yin Wong, T. Barnes, E. S. Swanson +1

Hadrons produced in high-energy heavy-ion collisions can suppress the production of J/psi and other charmonium states by charmonium spontaneous dissociation as the hot hadronic env…

Heavy Quarkonium Dissociation Cross Sections in Relativistic Heavy-Ion Collisions

Cheuk-Yin Wong, E. S. Swanson, T. Barnes

Many of the hadron-hadron cross sections required for the study of the dynamics of matter produced in relativistic heavy-ion collisions can be calculated using the quark-interchang…

Cross Sections for pi- and rho-induced Dissociation of J/psi and psi'

Cheuk-Yin Wong, E. S. Swanson, T. Barnes

We evaluate the cross sections for the dissociation of $J / ψ$ and $ψ^{'}$ by $π$ and $ρ$ at low collision energies, using the quark-interchange model of Barnes and Swanson. The dissoci…

Hybrid and Conventional Mesons in the Flux Tube Model: Numerical Studies and their Phenomenological Implications

T. Barnes, F. E. Close, E. S. Swanson

We present results from analytical and numerical studies of a flux tube model of hybrid mesons. Our numerical results use a Hamiltonian Monte Carlo algorithm and so improve on prev…

$I = 0, 1$ $π π$ and $I = 1/2$ $K π$ Scattering using Quark Born Diagrams

Z. Li, M. Guidry, T. Barnes +1

We extend the quark Born diagram formalism for hadron-hadron scattering to processes with valence $q q ˉ$ annihilation, specifically $I = 0$ and $I = 1$ $π π$ and $I = 1/2$ $K π$ elastic…

NN Core Interactions and Differential Cross Sections from One Gluon Exchange

T. Barnes, S. Capstick, M. D. Kovarik +1

We derive nonstrange baryon-baryon scattering amplitudes in the nonrelativistic quark model using the ``quark Born diagram" formalism. This approach describes the scattering as a s…
