Measurement of the transverse momentum dependence of the elliptic flow of charged particles in lead-lead collision at √(s_NN )=2.76 TeV
Summary, in English
In this thesis I investigate elliptic flow (second order of flow) using Fourier expansion of azimuthal distribution. The elliptic flow is in almond shape. All the analyses in this thesis have been obtained by a C++ analysis program which utilizes the ROOT framework. First part has been measured elliptic flow with the method "event plane". The second part has been measured elliptic flow with the method "cumulant". The second part consist of 2-particle cumulant and 4-particle cumulant. The number of events used in this analysis, are 11,154,977 from the TPC (the main part of ALICE detector). The analyses is divided to different centrality collision. The main part of this thesis has been measured elliptic flow as a function of transverse momentum especially at low transverse momentum.
