Short talk (15min. + 5 min. Q/A)

We present a study of proton–deuteron separation in the Liquid Argon In A Testbeam (LArIAT) experiment at Fermilab. LArIAT, which operated from 2015-2017, was designed to study and characterise charged particles in liquid argon that commonly occur in neutrino-Ar interaction final-states. Deuterons are rare and subject to significant background contamination in the LArIAT dataset, and their...

Short talk (15min. + 5 min. Q/A)

The efficient classification of electromagnetic activity from $\pi^0$ and electrons is a notoriously challenging problem in the reconstruction of neutrino interactions in Liquid Argon Time Projection Chamber (LArTPC) detectors. We address this problem using the mathematical framework of Optimal Transport (OT), which has been successfully employed for event classification in other HEP contexts...
