The Liquid Argon Time Projection Chamber (LArTPC) represents one of the most advanced experimental technologies for physics at the Intensity Frontier due to its full 3D-imaging, excellent particle identification and precise calorimetric energy reconstruction. By deploying LArTPCs in a dedicated calibration test beam line at Fermilab, LArIAT (Liquid Argon In A Testbeam) aims to experimentally calibrate this technology in a controlled environment and to provide physics results key to the neutrino oscillation physics and proton decay searches of the Short Baseline Neutrino and Long Baseline Neutrino programs.
LArIAT has a vast physics program which ranges from the analysis of electromagnetic shower reconstruction for electron-gamma separation, to the determination of the muon sign in the absence of magnetic field via its capture on nuclei, to the study of nuclear effects such as pion and kaon characteristic interaction modes.
In this talk, I will present the technique to measure the hadron-argon cross section in the LArIAT experiment, focusing on the study of the Total Kaon Cross Section and measurement of the Total Pion Cross Section, LArIAT first result.
