11:45 → 12:30 Search for numu disappearance at ICARUS

The ICARUS collaboration has completed a search for muon-neutrino disappearance from oscillations including eV scale sterile neutrinos using data collected with the Booster Neutrino Beam at Fermilab during 2022-2023 (ICARUS Run 2). Events are reconstructed with two different reconstruction frameworks and we select events with 1 muon, at least 1 proton, and no pions in the final state. A new fitting framework, called PROfit, was developed for this analysis and used for the final results presented here. As a single detector oscillation search this analysis is systematics limited, but the tools shown here will serve as a building block for future SBN searches where systematics will be constrained by the addition of a near detector. I will discuss the details of the analysis with a focus on the fitting framework, mock data studies, and the final fitting procedure during the data unboxing.
