Feasibility studies for key jet measurements at the Electron-Ion Collider

ORAL

Abstract

Jet quenching is one of the key signatures of the quark-gluon plasma. The accepted explanation for this effect is parton energy loss due to medium-induced radiation. QCD-based calculations describe parton energy loss in cold nuclei and the hot quark-gluon plasma on an equal footing. The Electron-Ion Collider (EIC) offers us a unique opportunity to understand the fundamental physics of quark energy loss in a controlled environment—with known parton kinematics, flavour, and medium length and density. I present an exploratory study of jet measurements in deep-inelastic scattering events at the EIC. One of the key measurements are lepton-jet angular correlations in e-p and e-A collisions, which will allow us to constrain jet transverse-momentum broadening and transverse-momentum dependent PDFs; with polarized beams, this observable also is sensitive to the quark Sivers effect. I use the projected integrated luminosities and momentum resolutions of current detector designs to obtain the sensitivity for key parameters controlling energy loss in cold nuclei.
