J/psi Production and Absorption in High Energy Proton-Nucleus Collisions
Charles Gale, Sangyong Jeon, Joseph Kapusta
Measured J/Psi production cross sections for 200 and 450 GeV/c protons incident on a variety of nuclear targets are analyzed within a Glauber framework which takes into account ene…
Coherence Time in High Energy Proton-Nucleus Collisions
C. Gale, S. Jeon, J. Kapusta
Precisely measured Drell-Yan cross sections for 800 GeV protons incident on a variety of nuclear targets exhibit a deviation from linear scaling in the atomic number A. We show tha…
Size of Fireballs Created in High Energy Lead-Lead Collisions as Inferred from Coulomb Distortions of Pion Spectra
Alejandro Ayala, Sangyong Jeon, Joseph Kapusta
We compute the Coulomb effects produced by an expanding, highly charged fireball on the momentum distribution of pions. We compare our results to data on Au+Au at 11.6 A GeV from E…
Nucleus-Nucleus Bremsstrahlung from Ultrarelativistic Collisions
Sangyong Jeon, Joseph Kapusta, Alexei Chikanian +1
The bremsstrahlung produced when heavy nuclei collide is estimated for central collisions at the Relativistic Heavy Ion Collider. Soft photons can be used to infer the rapidity dis…
Multiple Scattering Expansion of the Self-Energy at Finite Temperature
Sangyong Jeon, Paul J. Ellis
An often used rule that the thermal correction to the self-energy is the thermal phase-space times the forward scattering amplitude from target particles is shown to be the leading…
