The Unbearable Burden of Being Light: Exploring the emergence of ordinary matter from quarks and gluons
Argonne Physics Division Colloquium - 8 Dec 2017
11:00 AM, Building 203 Auditorium

In our everyday world, quarks and gluons, forever hide inside protons and neutrons. While their fundamental properties are encoded in the theory of quantum chromodynamics (QCD), many phenomenological aspects of QCD dynamics remain poorly understood. When gluons are massless and the quarks carry only a small fraction of the mass of a nucleon, how do nucleons acquire their large mass? How does nuclear matter emerge from the hot quark-gluon plasma that permeated the universe shortly after the Big Bang? What are the limits of ordinary nuclear matter at high density, e.g. in the interior of neutron stars or neutron star mergers? My talk will explain where our investigation of these questions stands, aided by experiments at the Relativistic Heavy Ion Collider and elsewhere, and how future facilities, such as an Electron-Ion Collider can help us finding the answers.
