We present the first measurement of negative pion total hadronic cross section on argon in a restricted phase space, which we performed at Liquid Argon In A Testbeam (LArIAT) experiment. All reaction channels, as well elastic interactions with scattering angle greater than 5° are included. The pions have kinetic energies range 100–700 MeV and produced by beam charged particles impinging solid target Fermilab test facility. LArIAT employs 0.24 ton active mass liquid time projection chamber (LArTPC) to measure interactions. For this measurement, has developed “thin slice method,” new technique sections LArTPCs. While moderately higher, our π−-Ar is generally agreement geant4 prediction.8 MoreReceived 3 August 2021Accepted 4 July 2022DOI:https://doi.org/10.1103/PhysRevD.106.052009© 2022 American Physical SocietyPhysics Subject Headings (PhySH)Physical SystemsPionsTechniquesNeutrino detectorsParticle interactionsParticles & Fields
