Description
We present a study of the charged kaon-Argon total interaction cross section in liquid argon performed at the LArIAT experiment. LArIAT is a Liquid Argon Time Projection Chamber (LArTPC) deployed in a dedicated calibration test beam at Fermilab. LArTPC represents one of the most advanced experimental technologies for physics at the Intensity Frontier due to its full 3D-imaging, excellent particle identification (PID) and precise calorimetric energy reconstruction. The LArIAT beamline instrumentation provides a measure of the initial momentum and PID of the particles entering the TPC. Therefore, the initial momentum of kaons tagged by the LArIAT beamline is measured before entering the TPC. The precise calorimetric energy reconstruction of the LArTPC technology enables the measurement of the total differential cross section for the tagged kaons. The kaon-Argon total interaction cross section has never before been measured in LAr; this measurement is a fundamental step to shed light on light meson interactions in nuclei. Additionally, this measurement provides key input to proton decay studies in future LArTPC experiments like DUNE.
