The Liquid Argon Time Projection Chamber in a Test Beam (LArIAT) experiment at the Fermilab
Test Beam Facility exposes a liquid argon time projection chamber (LArTPC) to a test beam to study
LArTPC responses to a variety of charged particles. LArIAT completed its first data-taking run in 2015,
so efforts are now underway to develop data analysis techniques for identifying charged particle events and
studying cross sections in liquid argon. Methods for analyzing the pion absorption and charge exchange
cross section in LArIAT will be presented including a likelihood-based particle identification algorithm.
Event identification techniques and cross section measurements from LArIAT can be applied directly or
further developed to improve precision in DUNE reconstruction and analysis.
Second Draft: Implemented all of Jen's suggestions from practice talk. Implemented John Paley's suggestions from 4/15/2016. Fixed a weird problem with subscripts in Powerpoint on the likelihood backup slide. Please let me know if any changes appear to be missing.
I plan to present the next draft of this talk next Monday at the APS April meeting. I have 10 minutes for my talk. Please let me know if you notice anything else that needs to be fixed or could be improved.
