"Transverse spherocity dependent correlation studies of initial spatial 
anisotropy and final azimuthal anisotropy in heavy-ion collisions at the 
LHC"


     címmel tartandó szemináriumára.


Kivonat:



Transverse spherocity (S0) is an event shape observable found to be 
relatively robust while separating the soft-QCD dominated isotropic 
events from the pQCD dominated jetty events. The application of 
transverse spherocity is not limited to the small systems only; 
recently, a few studies suggest that it can successfully be applied in 
heavy-ion collisions as well. In this work, we apply transverse 
spherocity to reveal the correlations between the initial spatial 
anisotropy and final state momentum azimuthal anisotropy in Pb-Pb 
collisions at $sqrt{s_{NN}}$ = 5.02 TeV using a multi-phase transport 
model (AMPT). It is found that eccentricity affects the event shape, as 
seen from the S0 values, while triangularity does not show any 
correlations with S0. On the other hand, both elliptic flow (v2) and 
triangular flow (v3) are found to be varying with different transverse 
spherocity selection cuts. We also report a transverse 
spherocity-dependent crossing point in transverse momentum (pT) between 
v2 and v3. The correlations of transverse spherocity with more widely 
used event shape observables, such as the reduced flow vectors, have 
also been reported. The sensitivity of transverse spherocity on some of 
the global observables in heavy-ion collisions, such as the Bjorken 
energy density, squared speed of sound, and the kinetic freeze-out 
parameters, have also been studied.
