MetadataShow full item record
The target of this thesis is to measure the elliptic flow v2 in p-Pb collisions using the data collected from the ALICE experiment in 2013. Elliptic flow in Pb-Pb is observed and is important for research in Quark Gluon Plasma (QGP), a new stage of matter created at very high energy density (ε ~ 1 GeV/fm3) and temperatures (T ~ 1015K) . This collective expansion was also already measured in p-Pb collisions using 2-Particle Correlation by ALICE experiment. This thesis used a different method to extract the v2: the Scalar Product. The elliptic flow in the first part of this thesis is studied for charged particles. In the second part particle identification studies are reported for π, K, p respectively. A subtraction had been done between the (0-20%) and (60-100%) multiplicity bins to remove non-flow effects and the v2 coefficient for charged particles and the particle species is reported.
