Calculations predict the temperature at which bottomonium melts in the hot matter created in heavy ion collisions.
Data on protons emitted from wide range of gold-gold collision energies shows absence of a quark-gluon plasma (QGP) at the lowest energy.
Spin orientation preference may point to a previously unknown influence of the strong nuclear force—and a way to measure its local fluctuations.
Study reveals that initial state conditions set up particle flow patterns, helping zero in on key properties of matter that mimics the early universe.
Theorists' hydrodynamic flow calculations accurately describe data from collisions of photons with lead nuclei at the ATLAS experiment.
Suppression of a telltale sign of quark-gluon interactions indicates gluon recombination in dense walls of gluons.
Quantum interference between dissimilar particles offers new approach for mapping gluons in nuclei, and potentially harnessing entanglement.
Physicists show that black holes and dense state of gluons—the “glue” particles that hold nuclear matter together—share common features.
Colliding gold nuclei at various energies enables scientists to investigate phases of nuclear matter and their possible co-existence at a critical point.
Theoretical study exploits precision of new heavy ion collision data to predict how gluons are distributed inside protons and neutrons
The results may offer insight into the quark-gluon plasma—the hot mix of fundamental nuclear-matter building blocks that filled the early universe.
Photon-deuteron collisions offer insight into the gluons that bind the building blocks of matter—and what it takes to break protons and neutrons apart.
