Short lived resonances can be used as a useful probe into the fundamental interactions that occur within the
collisions of particles at high energy, as conducted in high energy experiments, such as the ones performed at
the A Large Ion Collider Experiment (ALICE) experiment at the Large Hadron Collider (LHC). The environments studied range from the broad hadronic interactions created within the collisions of protons at unexplored centre-of-mass energies, to an entirely different form of hadronic matter created in the hot and dense region resulting from colliding heavy ions at high energy. However, due to the short lifetimes of resonances, they cannot be measured directly and instead must be studied using the products they decay into. The analysis conducted focuses on the extraction of a number of resonances seen in the π\(^+\) π\(^-\) channel; the invariant mass spectrum created contains many components which need to be accounted for within the extraction process, which also requires numerous corrections applied to it in order to accurately measure the desired peaks.
