The Muon g-2 experiment, FNAL E989, collected muon beam data over six accelerator operations years from 2017 to 2023. Since the final experimental uncertainty is expected to be statistically limited, time during accelerator-on periods was spent almost entirely on collecting “production” quality muon data and the necessary associated magnetic field measurements (“trolley runs”). Limited time...
We present a compact scintillating fibre timing detector developed for the Mu3e experiment. Mu3e is one of the flagship experiments of the Swiss particle physics scene, aiming to search for the charged lepton flavour violating “neutrinoless” muon decay (μ+ -> e+e+e-). Mu3e is planned to start taking data in 2025 at the Paul Scherrer Institute (CH), using the world's most intense continuous...
For accelerator neutrino experiments, an accurate prediction of the incoming neutrino flux is crucial for reducing uncertainties for all physics measurements. In this exciting period for the Short-Baseline Neutrino program at Fermilab, with far detector (ICARUS) already operating and the near detector (SBND) nearing operation, an updated flux model for the Booster Neutrino Beam (BNB) is...
The Short-Baseline Near Detector (SBND) is a Liquid Argon Time Projection Chamber (LArTPC) neutrino detector located in the Booster Neutrino Beam (BNB) at Fermilab, and is part of the Short-Baseline Neutrino (SBN) Program. The detector is currently being commissioned and has collected its initial neutrino beam dataset. This poster will detail the effort to commission SBND, including the...
The T2K near detector ND280 is used to constrain cross-section and flux models in the neutrino oscillation analysis. To improve the physics capabilities of the experiment, the upstream part of the detector is modified by adding a new highly granular scintillator detector (Super-FGD), two High-Angle TPCs and six thin Time-of-Flight scintillator layers. This poster focuses on the Super-FGD,...
Neutrino-nucleus cross section measurements are needed to improve interaction modeling to enable precision oscillation measurements and searches for physics beyond the standard model. This poster presents the methodology and application of data-driven model validation, which supplements “traditional” fake-data driven model validation with direct comparison to the reconstructed data. Through...
Current and future large neutrino liquid argon time projection chamber (LArTPC) experiments can broaden their physics reach by incorporating isolated MeV-scale features present in their data. In this study, we use data from the MicroBooNE detector, an 85 tonnes LArTPC exposed to Fermilab neutrino beams from 2015 until 2021, to demonstrate new calorimetric and particle discrimination...
There are several long-baseline neutrino oscillation experiments around the world, which study neutrino properties by observing the effects of neutrino oscillations over long distances. Most of these experiments also have near detectors to constrain the properties of the neutrino beam, such as its flux and energy spectrum, and to control systematic uncertainties. To achieve a narrower neutrino...
The Precision Reactor Oscillation and SPECTrum (PROSPECT) reactor antineutrino experiment is designed to detect eV-scale sterile neutrino oscillation at short baselines. PROSPECT's segmented detector is positioned approximately 7 meters away from the compact research reactor core at Oak Ridge National Laboratory's High Flux Isotope Reactor. During the data collection period, certain...
We present the first measurement of differential cross sections for charged-current muon neutrino interactions on argon with one muon, two protons, and no pions in the final state, using the MicroBooNE Liquid Argon Time Projection Chamber. Such interactions leave the target nucleus in a two-particle two-hole state; these states are of great interest, but currently, there is limited information...
A comprehensive international effort has been underway to elucidate the properties and behaviors of neutrinos. A major source of systematic uncertainties in studying neutrino-induced interactions comes from neutrino-nucleus cross-section models, highlighting the need for more precise statistical measurements. MINERvA, an on-axis neutrino-nucleus scattering experiment located at the Fermi...
The NOvA experiment, a long-baseline neutrino experiment based at Fermilab, is dedicated to measuring various neutrino oscillation parameters with high precision. One of the significant contributions to systematic uncertainty in these measurements is the cross-section systematics, which arises from an incomplete understanding of nuclear models and neutrino-nucleus interactions. Recently, there...
LArIAT is a liquid argon time projection chamber (LArTPC) experiment in a test beam, took data at Fermilab from 2015 to 2017 to understand and characterize interactions of particles in LAr which are commonly observed in neutrino-Ar final-states. In LArTPCs tracks for pions and muons that stop in the TPC have similar ionization profiles, making the particle identification hard. We are...
The MicroBooNE detector is a liquid argon time projection chamber with an active mass of 85 tons. It is located in the Fermilab Booster Neutrino Beam, where it collected data from 2015 to 2020. As part of its primary scientific objectives, MicroBooNE aims to extract precise measurements of muon neutrino - argon charged current interaction cross-sections.

A detailed understanding of muon neutrino charged-current interactions on argon is crucial to the study of neutrino oscillations in current and future experiments using liquid argon time projection chambers. To help fill this need, MicroBooNE has produced a comprehensive set of cross section measurements which simultaneously probe the leptonic and hadronic systems by dividing the inclusive...
In this poster, we shall report neutrino cross sections for the kinematic region defined as Shallow Inelastic Scattering (1.5 $<$ W $<$ 2.0 GeV) at MINERvA, located at Fermilab. These cross sections will be on the hydrocarbon central tracker exposed to the NuMI ME beam with neutrino energy peaked at around $E_{\nu} = 6$ GeV. The SIS region has never been specifically studied, and thus the...
The non-standard interaction (NSI) of neutrinos mediated by a scalar particle is an interesting new physics scenario to explore in oscillation experiments. The scalar NSI contribution appears as a perturbation to the mass term in the neutrino Hamiltonian, giving a unique possibility of probing absolute neutrino mass through oscillations. The linear scaling of scalar NSI with matter density...
We have developed a neutrino detector with threshold energies from ~0.2 to 100 MeV in a clean detection mode almost completely void of spurious backgrounds. It was initially developed for the NASA neutrino Solar Orbiting Lab project to put a solar neutrino detector very close to the Sun with 1000 to 10,000 times more solar neutrino flux than on Earth, but similar interactions have been found...
A novel three-dimensional projection scintillator tracker called SuperFGD is one of the key components of the near detector upgrade of the T2K experiment. Due to the nanosecond timing resolution and fine granularity, SuperFGD will provide essential data for studying neutrino interactions. A prototype of the SuperFGD detector was exposed to a neutron beam at LANL to study its response to...
Portrait of a Scientist aims to deconstruct stereotypes about what a scientist looks like and how they act by showcases people's multifaceted identities. Participants are asked to complete the phrase "I am a scientist and I also..." with any hobby, role, or identity that they feel comfortable sharing. The most engagement with the project, which has been running since 2021, has occurred when...
EMPHATIC (Experiment to Measure the Production of Hadrons At a Test beam In Chicagoland) is a Fermilab-based table-top size experiment focused on hadron production measurements.

The nuclear emulsion, with its sub-micron positional resolution, allows for detecting low-momentum charged particles such as protons with a threshold of 200 MeV/c....
MicroBooNE is a liquid argon time projection chamber in the Booster Neutrino Beam at Fermilab. One of MicroBooNE's primary goals is to investigate the MiniBooNE low energy excess of events containing a single electromagnetic shower. The largest predicted source of single shower events is charged current electron neutrino interactions, but MicroBooNE has disfavored an excess of this topology in...
The Lorentz Invariance is the foundation of other successful theories, like quantum field theory, and is connected to fundamental symmetries, like charge, parity, and time reversal (CPT), which is essential in the Standard Model of particle physics. Alternative theories proposing that Lorentz Invariance may break in some scales have been considered in the context of neutrino oscillations, as...
