Difference in the endpoint along the detector length (Z) between the truth-level information and the calibrated reconstructed information for the 6 GeV=c simulation sample. The mean offset measured in the 6 GeV=c simulation sample is 0.539 cm with a standard deviation of 1.231 cm using a Gaussian fit.

ProtoDUNE Single-Phase (ProtoDUNE-SP) is a 770-ton liquid argon time projection chamber that operated in a hadron test beam at the CERN Neutrino Platform in 2018. We present a measurement of the total inelastic cross section of charged kaons on argon as a function of kaon energy using 6 and 7 GeV / c beam momentum settings. The flux-weighted averag...

... To advance this analysis in future LArTPC measurements, it is necessary to increase statistics, reduce large detector systematics (especially those related to the recombination of electrons with argon nuclei), refine reconstruction algorithms for short tracks, and improve the identification of kaon tracks that undergo reinteractions. Furthermore, the uncertainty related to kaon reinteractions on argon nuclei could be refined by using data from LArIAT [46], and the DUNE prototypes at CERN [48]. More statistics will come from analyzing MicroBooNE's full dataset with a total of 1.2 ×10 21 POT. ...

  • Feb 2025
The MicroBooNE experiment is an 85 tonne active mass liquid argon time projection chamber neutrino detector exposed to the on-axis Booster Neutrino Beam (BNB) at Fermilab. One of MicroBooNE's physics goals is the precise measurement of neutrino interactions on argon in the 1 GeV energy regime. Building on the capabilities of the MicroBooNE detector, this analysis identifies K+K^{+} mesons, a key signature for the study of strange particle production in neutrino interactions. This measurement is furthermore valuable for background estimation for future nucleon decay searches and for improved reconstruction and particle identification capabilities in experiments such as the Deep Underground Neutrino Experiment (DUNE). In this letter, we present the first-ever measurement of a flux-integrated cross section for charged-current muon neutrino induced K+K^{+} production on argon nuclei, determined to be 7.93 ±\pm 3.27 (stat.) ±\pm 2.92 (syst.) × 10−42  \times~10^{-42}\; cm2^2/nucleon based on an analysis of 6.88×1020\times10^{20} protons on target.
