Title: Searches for a droplet of hydrodynamic fluid at the LHC

Abstract:
*********************************************************************
The primary goal of the ultra-relativistic heavy-ion collision program
at the Large Hadron
Collider (LHC) is to study the properties of the Quark-Gluon Plasma
(QGP), a novel state of
strongly interacting matter which exists in the early universe. Anisotropic
flow, which quantifies the anisotropy of the momentum distribution of
nal state particles, is sensitive to the
fluctuating initial conditions and the transport properties of the
created QGP. The successful description of
the measured anisotropic flow coefficients by hydrodynamic calculations
suggests that the created
medium behaves like a nearly perfect fluid. In this seminar, I will
present the latest
ow measurements in high energy heavy-ion collisions at the LHC. In
addition, I will highlight the most recent
development in the study of flow in small collisions systems, including
proton-lead at
sNN = 5.02 TeV and proton-proton collisions at sNN = 13 TeV and discuss
the possible creation of QGP
fluid with its smallest size.
