Abstract

This work reports a Monte Carlo study of Δ⁺⁺ resonance production and decay in p-p collisions at = 10 TeV. For this study case, the ALICE detector at the LHC collider has been chosen. The Δ⁺⁺ → πp decay is studied using a simulation of the full ALICE detector response. Special care is taken to extract the signal using the event-mixing technique for background estimation. Results from a 4.8 million events sample are presented. This number of events corresponds to a few days data-taking at the nominal acquisition rate and luminosity.
