Kaon production cross section with MicroBooNE

MicroBooNE is an 85-tonne active mass liquid argon time projection chamber (LArTPC) neutrino detector that collected data on the Booster Neutrino Beamline (BNB) at Fermilab from 2015 to 2020. One of the key physics goals is the precise measurement of neutrino interactions on argon in the 1 GeV energy regime. Due to their mass, kaons are rarely produced in this energy regime. Nevertheless, the study of kaon production in MicroBooNE offers an unprecedented opportunity to investigate nuclear modeling and LArTPC detector performances for kaon identification. The study of kaons in neutrino interactions will help to improve the background estimates for future nucleon decay searches in experiments such as DUNE, and it will allow the development of techniques to enhance the particle identification capabilities of a LArTPC. In this talk, we present the first-ever cross section measurement of charged current muon neutrino-induced kaon production on argon using MicroBooNE datasets.
