Prospect studies for Proton-Oxygen Collisions at ATLAS, LHCf and AFP — Yusuf Can Çekmecelioğlu2, •Erik Dieckow1, Cigdem Issever1,2, and Clara Elisabeth Leitgeb2 — 1Humboldt Universität zu Berlin, Germany — 2DESY, Zeuthen, Germany
In astroparticle physics, ground based analysis is done by studying cosmic ray induced showers in the Earth's atmosphere. The phenomenological models used to simulate the interaction of cosmic ray particles with the atmospheric nuclei cause large systematic uncertainties and thus need improvement. In the past, LHC has conducted proton-proton and proton-heavy nucleus (lead) collisions. In LHC run 3 there will be the opportunity to study proton-Oxygen collisions. The cross-sections and particle energy spectra in the forward regions that will be measured with this data can provide invaluable and complementary input to the aforementioned models. The main focus of these studies is on the feasibility of a combined data taking of LHCf, ATLAS and AFP detectors during the proton-Oxygen collision run. This would allow for a better reconstruction of the event kinematics, as well as a purer selection of low mass single diffraction events than would be possible with LHCf data only.
