Grid technologies in SPbSU long-range correlations analysis and MC simulations for ALICE

Studies of long-range correlations within the physics program of ALICE [1] require a high accuracy statistical analysis of experimental data. In this report, examples of Grid technologies used for the analysis of several types of correlations in proton-proton and Pb-Pb collisions in ALICE are presen...

description Studies of long-range correlations within the physics program of ALICE [1] require a high accuracy statistical analysis of experimental data. In this report, examples of Grid technologies used for the analysis of several types of correlations in proton-proton and Pb-Pb collisions in ALICE are presented. The main stages of software development and debugging on the basis of the AliAnalysis Manager [2] platform are described, allowing one to make calculations with both local and distributed computing systems (PROOF [3, 4], Grid). Examples of Monte-Carlo calculations are also given. A distributed storage and data processing system (ALICE Environment Grid [5, 6]) providing access to experimental data and results of modeling of proton-proton and Pb-Pb collisions is described. The analysis of large data (tens of Tb) allowed one to obtain results with statistics of more than 20 million events as well as to investigate a topological structure of long- range correlations.
