266. Quarkonium production near threshold at JLab and EIC, and the quantum anomalous energy of the proton

Sylvester Joosten (Argonne National Laboratory)

4/16/21, 3:30 PM

Oral Presentation

Quarkonium in exclusive electro- and photoproduction provides for a unique probe to the gluonic structure of the nucleon. A new generation of experiments at Jefferson Lab in the 12 GeV era, and at the electron-ion collider (EIC) will use near-threshold quarkonium production to study topics related to the role of the quantum anomalous energy in the origin of the proton mass, the nature of the...

189. Probing the Hadronic Spin Structure and Dynamics in High-Energy Polarized Proton-Proton Collisions at RHIC

Matt Posik (Temple University)

4/16/21, 4:00 PM

Oral Presentation

The Relativistic Heavy-Ion Collider (RHIC) is a unique facility. It is the world's only polarized proton + proton collider capable of delivering highly polarized protons up to a center-of-mass energy of 510 GeV. Polarized proton + proton collisions allow one to study the proton's spin structure using strong interactions by measuring single and double spin asymmetries. Using longitudinally...

193. Equilibration of a Heavy Ion Collision

Derek Teaney (Stony Brook University)

4/16/21, 4:30 PM

Oral Presentation

I describe recent work on the equilibration process in heavy ion collisions by outlining some old ideas from QCD kinetics, and their recent realizations in practical computer codes. These calculations connect hydrodynamic phenomenology in large nuclei with properties of the incoming wave-functions, placing reasonable constraints on the magnitude of the saturation scale in central heavy ion...
