Yesterday at 7:46 pm the first stable beams of the LHC 2023 heavy-ion run have been recorded. The heavy-ion run allows CMS scientists to study states of matter similar to those of the early universe.
During this period, the CERN accelerators operate…
Our best understanding of the early Universe tells us that a dense medium, known as the quark-gluon plasma (QGP), existed in the first microseconds after the big bang. These early-Universe conditions can be mimicked in particle colliders by smashing…
