“Impact of elliptic flow on higher order flow coefficients in heavy-ion 
collisions at the LHC”


címmel tartandó szemináriumára.


Kivonat:



Anisotropic flow coefficients ($v_{n}$) and their fluctuations are sensitive 
observables that are affected by the transport properties of the systems 
formed in heavy-ion collisions. The sensitivity of $v_{n}$ increases with an 
increase in the value of $n$. However, $v_n$ with $n\geq 4$ have nonlinear 
contributions from elliptic flow ($v_2$) and triangular flow ($v_3$), which 
dilutes the system response to these coefficients. In this presentation, 
using the event shape observable, transverse spherocity, events with smaller 
and larger values of $v_2$ can be selected, which is used to reduce the 
contribution of $v_2$ from higher order coefficients. It is observed that the 
higher-order flow coefficients show enhanced damping effects with a change in 
collision centrality for the events with smaller values of elliptic flow. 
Transverse spherocity dependence of elliptic flow fluctuations is also 
explored, which shows that the fluctuations are higher for the events with 
larger values of transverse spherocity.
