A short introduction to heavy-ion physics
Sourendu Gupta
Heavy-ion collisions provide the only laboratory tests of relativistic quantum field theory at finite temperature. Understanding these is a necessary step in understanding the orig…
On the thermalization of quarkonia at the LHC
Sourendu Gupta, Rishi Sharma
We argue that the relative yields of states observed at the LHC can be understood as bottomonium states coming to early thermal equilibrium and then freezing out. The bottomoni…
Strange freezeout
S. Chatterjee, R. M. Godbole, Sourendu Gupta
We argue that known systematics of hadron cross sections may cause different particles to freeze out of the fireball produced in heavy-ion collisions at different times. We find th…
Phases and properties of quark matter
Sourendu Gupta
I review recent developments in finite temperature lattice QCD which are useful for the study of heavy-ion collisions. I pay particular attention to studies of the equation of stat…
A systematic expansion for relativistic causal hydrodynamics
Sourendu Gupta
A systematic expansion of the Boltzmann equation for the diffusion of dilute tracers, in powers of the Knudsen number, carried out to next-to-leading order (NLO), gives the relativ…
Aspects of causal viscous hydrodynamics
R. S. Bhalerao, Sourendu Gupta
We investigate the phenomenology of freely expanding fluids, with different material properties, evolving through the Israel-Stewart (IS) causal viscous hydrodynamics, and compare…
