Collectivity, as interpreted to mean flow of a dense medium in high-energy A-A collisions described by hydrodynamics, has been attributed to smaller collision systems -- p-A and even p-p collisions -- based on recent analysis of LHC data.…
Recent RHIC data have suggested an interesting scenario where jets, after being formed in the very first instants of the nuclear collision, interact strongly and are absorbed by the hot and dense matter subsequently created. In this…
Dijets observed near midrapidity in high-energy nuclear collisions result from large-angle scattering of low-$x$ partons (gluons) within projectile hadrons as a signature manifestation of QCD. Within the same collisions it has been claimed…
