A simulation-based feasibility study of the measurement of KL0 in ALICE — •Laura Gans-Bartl for the ALICE Germany collaboration — Institut für Kernphysik, Goethe-Universität Frankfurt
The ALICE experiment is designed to study the characteristics of hot and dense nuclear matter created in heavy-ion collisions. The measurement of a large variety of identified particles can help to better understand the underlying physics processes at play, while particle production in proton proton (pp) collisions serves as a baseline for these measurements. Charged pions, for example, can be measured with the main tracking detectors of the experiment, while neutral pions can be reconstructed from decay photons measured with electromagnetic calorimeters. The production of one of the eigenstates of the neutral Kaon, KS0, has already been measured in pp collisions by the ALICE collaboration1. The KL0 has not been measured so far, as the measurement is more challenging due to the long flight time of the KL0.
In this contribution, a simulation-based feasibility study of KL0 → π+π−π0, π0 → γ γ in pp collisions with ALICE is presented. Based on a PYTHIA simulation, the impact of the efficiency and acceptance of the ALICE experiment on the measurement probability of KL0 is studied. An estimate of the KL0 yield with ALICE Run2 statistics is discussed.
