It uses a liquid Argon time projection chamber (LArTPC) to detect neutrino events from a flux of predominantly muon neutrinos. In 2018, its predecessor MiniBooNE published results showing the detection of a significant excess of electromagnetic events in its data compared to expectation. The MiniBooNE anomaly defied...
Long-baseline neutrino experiments such as NOvA, T2K, DUNE, and Hyper-Kamiokande measure neutrino oscillations using charged current (CC) neutrino interactions. CC interactions in long-baseline experiments consist of three types of interactions, whose relative fraction depends on the neutrino energy quasielastic (QE), resonant (RES) or Deep Inelastic Scattering (DIS). Precise measurements of...

Long-baseline neutrino experiments, such as NOvA, T2K, and DUNE, are working to measure neutrino oscillation parameters and will benefit from reduced neutrino flux uncertainties. The dominant source of neutrino flux uncertainty arises from an insufficient knowledge of parent hadron yields from neutrino production targets. Using external hadron production measurements, we can significantly...
LArIAT (Liquid Argon In A Testbeam) is a LArTPC experiment which aims to understand and characterize interactions of neutrino final-state products with Argon. Differentiation between muons and pions in LArTPCs is difficult since the tracks for both particles exhibit very similar ionization densities. We are exploring unique new particle discrimination capabilities for pions and muons by...

Boosted Dark Matter (BDM) is a dark matter (DM) model that uses a minimal U(1)’ extension to the Standard Model (SM) of particle physics. By introducing three DM particles $χ_0$,$χ_1$,and $χ_2$ and the dark photon (DP) X to the dark sector, gravitational anomalies can be explained, and the interactions with the SM can exist via a kinetic mixing between the DP and the SM photon. An interesting...

In the naive Drell--Yan model, the angular distribution of the Drell--Yan process has zero $\cos2\phi$ modulation, where $\phi$ denotes the azimuthal angle of dimuons in the Collins--Soper frame. However, a sizable $\cos 2\phi$ dependence was observed in pion-induced Drell--Yan experiments, such as the NA10 and E615 experiments. The Boer--Mulders function is a transverse momentum dependent...
The $J/\psi$ particle is a spin-1 charmonium state with significant decay fraction towards lepton pairs. The distribution of decay particles from the $J/\psi$ is influenced by its spin alignment, which provides insights into different production mechanisms. SeaQuest, a fixed target experiment at Fermilab, was designed to observe muon pairs from charmonium and Drell-Yan production in $pp$ and...
Study of angular distributions in the Drell-Yan process is a valuable tool for unraveling the structure of hadrons. Measuring the $\cos2\phi$ angular dependence, where $\phi$ denotes the azimuthal angle of dimuons in the Collins-Soper frame, can be used to extract the Boer-Mulders (BM) function. The BM function describes the transverse-polarization asymmetry of quarks within an unpolarized...
Upcoming surveys are predicted to discover galaxy-scale strong lenses on the magnitude of $10^5$, making deep learning methods necessary in lensing data analysis. Currently, there is insufficient real lensing data to train deep learning algorithms, but training only on simulated data results in poor performance on real data. Domain adaptation can bridge the gap between simulated and real...
Dwarf galaxies are the oldest, least evolved, and most dark-matter-dominated galaxies in the universe, therefore studying them can shed light on the formation of some of the first galaxies to exist, the evolution of larger host galaxies like our Milky Way, as well as the abundance and distribution of dark matter across the Local Universe. Most research to date involving dwarf galaxies has...
The planning and execution of observational cosmology campaigns have undergone a substantial increase in complexity, particularly for advanced telescopes like the Rubin Observatory’s LSST, JWST, and the Nancy Grace Roman telescope.

HEP software requires both general computational skills and domain knowledge of the field. In my experience, more and more young students lack the software knowledge needed to contribute to the HEP community. IRIS-HEP and the HSF have programs designed to bridge this gap for young scientists through training events. Specifically, I mention the Software Basics Training workshops that teach...
Modern deep neural networks comprise many operational layers, such as dense or convolutional layers, which are often collected into blocks.In this work, we introduce a new, wavelet-transform-based network architecture that we call the multi-resolution perceptron: by adding a pooling layer, we create a new network block, the WavPool.
The first step of the multi-resolution perceptron is...
