More information:
Quantum Chromodynamics (QCD), which describes the interaction of quarks and gluons, is one of the cornerstones of modern physics. The asymptotic freedom of QCD explains the deconfined state of nuclear matter, known as quark-gluon plasma (QGP), created in an extremely hot and dense environment, such as the Big Bang and relativistic heavy-ion collisions. At the opposite end of the temperature spectrum, cold quarks and gluon must be confined inside hadrons. Currently, many properties of hadrons, such as mass and spin, are not well understood in terms of the underlying quark-gluon dynamics. Therefore, an Electron-Ion Collider (EIC), the finest nucleon microscope in the world, is proposed to probe quarks and gluons (collectively known as partons) confined in nucleons. This talk will first cover recent studies of the deconfined QGP via measurements of its bulk properties and QGP effects on particle jets at LHC and RHIC experiments. The second half of the talk will introduce the future EIC experiments to study partonic structure with two key instruments, a low-material-budget forward silicon tracker and a compact modular RICH detector.
