Nuclear modification of hadron production measured by ALICE

The Large Hadron Collider (LHC) collides lead nuclei at an unprecedented centre of mass energy of 2.76 TeV/nucleon to measure the properties of the strongly interacting matter when partons are liberated from nucleons and create a Quark Gluon Plasma. The highly energetic partons propagating through m...

Description
Summary:The Large Hadron Collider (LHC) collides lead nuclei at an unprecedented centre of mass energy of 2.76 TeV/nucleon to measure the properties of the strongly interacting matter when partons are liberated from nucleons and create a Quark Gluon Plasma. The highly energetic partons propagating through medium are absorbed and thus probe its characteristics. The highly energetic hadrons produced by fragmentation of these partons, provide information about the energy loss of the original quarks and gluons. The energy loss can be studied by measuring the modification of hadron spectra and correlations produced in heavy ion collisions with respect to proton-proton. The ALICE experiment is one of 4 large LHC experiments. It is dedicated to the study of the strong force by colliding heavy ions. The modifications of high momentum particle spectra and their correlation, measured by ALICE experiment, are presented. The consequences of these measurements on the evolution of strongly interacting matter are discussed.
