First Measurement of ν_{e} and ν[over ¯]_{e} Charged-Current Single Charged-Pion Production Differential Cross Sections on Argon Using the MicroBooNE Detector.

Understanding electron neutrino interactions is crucial for measurements of neutrino oscillations and searches for new physics in neutrino experiments. We present the first measurement of the flux-averaged ν_{e}+ν[over ¯]_{e} charged-current single charged-pion production cross section on argon using the MicroBooNE detector and data from the NuMI neutrino beam. The total cross section is measured to be [0.

First Double-Differential Cross Section Measurement of Neutral-Current π^{0} Production in Neutrino-Argon Scattering in the MicroBooNE Detector.

We report the first double-differential cross section measurement of neutral-current neutral pion (NCπ^{0}) production in neutrino-argon scattering, as well as single-differential measurements of the same channel in terms of final states with and without protons. The kinematic variables of interest for these measurements are the π^{0} momentum and the π^{0} scattering angle with respect to the neutrino beam. A total of 4971 candidate NCπ^{0} events fully contained within the MicroBooNE detector are selected using data collected at a mean neutrino energy of ∼0.

Search for a Hidden Sector Scalar from Kaon Decay in the Dimuon Final State at ICARUS.

We present a search for long-lived particles (LLPs), produced in kaon decays, that decay to two muons inside the ICARUS neutrino detector. This channel would be a signal of hidden sector models that can address outstanding issues in particle physics such as the strong CP problem and the microphysical origin of dark matter. The search is performed with data collected in the Neutrinos at the Main Injector (NuMI) beam at Fermilab corresponding to 2.

Measurements of Pion and Muon Nuclear Capture at Rest on Argon in the LArIAT Experiment.

We report the measurement of the final-state products of negative pion and muon nuclear capture at rest on argon by the LArIAT experiment at the Fermilab Test Beam Facility. We measure a population of isolated MeV-scale energy depositions, or blips, in 296 LArIAT events containing tracks from stopping low-momentum pions and muons. The average numbers of visible blips are measured to be 0.

First Simultaneous Measurement of Differential Muon-Neutrino Charged-Current Cross Sections on Argon for Final States with and without Protons Using MicroBooNE Data.

We report the first double-differential neutrino-argon cross section measurement made simultaneously for final states with and without protons for the inclusive muon neutrino charged-current interaction channel. The proton kinematics of this channel are further explored with a differential cross section measurement as a function of the leading proton's kinetic energy that extends across the detection threshold. These measurements use data collected with the MicroBooNE detector from 6.
