Monte Carlo Templates in the Measurement of Neutral Pions with the ALICE EMCal — •Marvin Hemmer for the ALICE collaboration — Institut für Kernphysik, Goethe-Universität Frankfurt
A hot and dense medium, the so-called quark-gluon plasma (QGP), is believed to be created in ultra-relativistic heavy-ion collisions. The dedicated heavy-ion experiment ALICE at the LHC is designed to study the properties of the QGP. Measurements in pp collisions function as a baseline for the measurements in Pb-Pb collisions and further provide insights into the particle production processes. In the ALICE experiment, neutral pions (π0) can be measured via their two-photon decay channel, using one of the calorimeters EMCal, DCal and PHOS.
In this poster, a study of the background subtraction in the π0 measurement in pp collisions at √s = 13 TeV with the EMCal using Monte Carlo templates will be presented.
