Description
At LHC energies, several pairs of partons can collide in each pp, pA or AA collision. Multiple Parton Interactions (MPIs) can affect many physical observables, such as the charged particle multiplicity and the average transverse momentum per event. In order to include jets down to the lowest energies ("minijets"), a two-particle correlation analysis is performed with the ALICE Detector. The correlation is expressed as associated yield per trigger particle and allows one to extract the number of uncorrelated seeds which in MC simulations is proportional to the number of MPIs. In this talk, the latest results for nearside and awayside per trigger yields and uncorrelated seeds as a function of VZERO multiplicity class are reported in p-Pb collisions recorded by the ALICE Detector. The talk will discuss how the number of MPIs scale with the number of nucleon-nucleon collisions which are typically calculated in Glauber MCs.
