We show that the incoherent elastic scattering of partons, as present in a multi-phase transport model (AMPT), with a modest parton-parton cross-section of $\sigma=1.5-3$ mb, naturally explains the long-range two-particle azimuthal correlation as observed in proton-proton, proton-nucleus and nucleus-nucleus collisions at the Large Hadron Collider. We calculate the elliptic, $v_2$, and...

In the hot and dense QCD matter, quarks and gluons are deconfined to form Quark-Gluon Plasma (QGP). The QGP, which existed in the early universe, can be created experimentally by the relativistic heavy ion collisions at RHIC and LHC. The dynamics of the QGP in these experiments is well described by relativistic hydrodynamics.
Recently event-by-event initial fluctuations have been included in...

The hydrodynamic fluctuations are thermal fluctuations arising in the
event-by-event hydrodynamic evoluation of the system, and its power
spectrum is determined through the fluctuation-dissipation relation.
While, the higher harmonics $v_n$ are systematically observed in RHIC and
LHC and attract a lot of theoretical and experimental interests. Initial
state fluctuations turned out to be...

Quark Gluon Plasma(QGP) is a phase of nuclear matter at high temperature and high energy density.
And this is experimentally formed by relativistic nucleus collisions at RHIC.
Flow measurements played an important role in understanding basic properties of QGP
, because it reflects the initial spatial anisotropy.
In 2012, Cu+Au collisions, the first asymmetric collisions of heavy...

Due to small cross section in the QGP direct photons preserve information about different stages of the heavy ion collisions.
Therefore, detailed measurement of direct photons can be considered as a powerful probe to study QGP physics.
Photons have different angular emission patterns depending on their production mechanism.
The second order azimuthal anisotropy ($v_{2}$) of direct photons...
