Event selection of charged current neutrino induced charged Kaon production in the MicroBooNE

The MicroBooNE experiment at Fermilab uses a liquid argon time projection chamber (LArTPC) to search for the anomalous production of electron-neutrino like events and to study neutrino-argon cross sections in the ~ 1 GeV energy regime. The neutrino induced kaon production in liquid argon is important in many aspects. First, for a proton decay experiment, the main background of concern is an atmospheric neutrino interacting with the detector medium and producing a kaon, mimicking the proton decay signal of proton decaying to charged kaon and neutrino. The other thing is that there are not many measurement in this channel. Ultimately this new measurement would help to better model the neutrino-argon interactions and hence better understand the neutrino oscillation parameters.In this talk we focus on how we use new tools for particle identification to achieve high purity tagging of neutrino induced charged kaons produced along with a muon in charged current interactions inside the MicroBooNE detector.
