Description
Neutral particle production in (anti-)neutrino interactions biases neutrino energy reconstruction, and of the neutral particles, neutron interactions in liquid argon are the least constrained by data. The mini-CAPTAIN LArTPC measured neutron interactions on argon from a neutron beam at Los Alamos National Laboratory in order to address this issue specifically. Using data from a low intensity beam intensity run, first measurement of neutron cross section at the 100-800 MeV range was made, and the energy averaged neutron cross-section was determined to be 0.91±0.10 (stat.)±0.09 (sys.) barns. This will be useful for the future of DUNE, as DUNE will determine the neutrino mass ordering and explore leptonic CP violation by measuring the electron (anti-)neutrino appearance from the mostly muon (anti-)neutrino beam produced at Fermilab. I describe the measurement and discuss future plans.
