NPA (Nuclear Particle Astrophysics) Seminar: Prithwish Tribedy, Brookhaven National Laboratory, “Novel collective phenomena in collisions of small systems at the LHC”

Experimental findings over the past decade have established that the QCD matter formed in relativistic heavy ion collisions behaves like a strongly interacting nearly perfect fluid that can be described by hydrodynamics. One of the most striking recent findings at the LHC is that a number of observations in the high multiplicity events of much smaller collision systems like proton-proton and proton-ion resemble features similar to relativistic heavy ion collisions. Such observations are often attributed to the formation of smallest droplets of Quark-Gluon-Plasma. In this talk I will discuss how the dynamics of saturated gluonic states in the colliding protons or nuclei can provide alternative interpretation of such phenomena.
