Synergies of pp and pA Collisions with an Electron-Ion Collider

Motivation

While a tremendous amount of effort is being expended toward the research and development of a future Electron-Ion Collider (EIC), any data from such a machine will need to be analyzed in the context of present and upcoming measurements at RHIC and the LHC. In this workshop we would like to obtain an overview of how the planned pp and pA data taking especially utilizing the forward detector upgrades at RHIC and the LHC can be leveraged to stimulate further theoretical developments necessary to interpret data from a future EIC.

In coordination with the corresponding theorists we would like to review how fundamental QCD concepts like factorization, universality, and initial- and final-state interactions are believed to relate measurements in proton-proton (-nucleus) collisions to electron-proton (-nucleus) collisions. Closely related are measurements of factorization breaking, perturbative and nonperturbative evolution, and spin asymmetries which can be measured in proton-proton and proton-nucleus collisions.

A particular focus will be on the unique information that can be obtained exclusively through hadronic collisions at RHIC and the LHC which is complementary to information accessible at an EIC. The outcomes of this workshop will help inform the measurements to be done using the planned forward upgrades to RHIC and the LHC in order to optimize their synergies with a future EIC.

Topics to be discussed are:

  • (un)polarized pp/pA universality tests
  • TMDs, Twist-3 and GPDs in pp
  • Factorization breaking in pp and pA
  • Diffraction in pp and pA what can we learn for ep and eA
  • Saturation in pA from RHIC to LHC
  • The must do measurements to access information only accessible in pp and/or pA

Presentations

Presentations will be mainly by invitation. We expect to be able to accommodate a limited number of contributed talks. If you are interested in presenting a contributed talk, please contact Elke-Caroline Aschenauer at elke@bnl.gov.

Evening Events

Participants are invited to attend off-site, no-host (self-pay) dinners during the Workshop. Location, time and cost to be determined. Payment will be "cash only" and will be collected by the organizers either during the workshop or at the dinners.
