PhD in Physics - Nuclear Physics in Boulder United States | University of Colorado Boulder

Nuclear physics explores the fundamental building blocks of matter - quarks and gluons - which constitute nearly all visible mass in the cosmos. These particles primarily exist within atomic nuclei, the central components of every atom that forms our physical world, including our own bodies. Scientists investigate profound questions about the universe's early moments following the Big Bang, when quarks and gluons existed as an extremely hot plasma. They examine how cosmic elements originated and how atomic nuclei form through powerful interactions between protons and neutrons. These nucleons themselves represent quark-based structures whose formation through gluon-mediated interactions in Quantum Chromodynamics remains partially understood and continues to be a vibrant research area.
