Strange particle production rates for the K0 s and Λ at √s = 13 TeV with ATLAS

After a long shutdown, the Large Hadron Collider (LHC) restarted activities in 2015 at center-of-mass energy √s = 13 TeV, up from √s = 8 TeV before its stop in 2012, producing new data at energies never before reached. At the end of this run, another long shutdown will take place in preparation for the LHC higher luminosity. During that time, the ATLAS experiment, like others, will be undergoing repairs and upgrades. A laboratory at McGill University will be testing the new small Thin Gap Chambers (sTGCs) for the replacement of the small muon detector wheels. First, the development of a reliable and robust control system for this facility is discussed. The core analysis follows, which is the measurement of the production rates of K0 s and Λ particles at the new center-of-mass energy √s = 13 TeV using data from ATLAS. It is the first time these measurements are done for this energy at the LHC. Mass measurements of 497.8±0.3(stat) MeV for the K0 s and 1115.71±0.02(stat) MeV for the Λ are obtained and kinematic distributions are shown.
