Beyond Detection: Zero-Shot UAS Payload Identification, Passive Ranging, and Pose Estimation

Gregory Matousek, Nathan Varberg, Pete Torrione, Namdi Brandon et autres

Unmanned Aerial Systems (UAS) pose a growing threat on the modern battlefield, demanding rapid detection and characterization capabilities for the warfighter. Existing single-model solutions are inadequate for Counter-UAS (C-UAS), as they struggle across varying ranges and cannot provide detailed contextual information beyond …

Impact of Future Dihadron Production Measurements on the Transversity Distributions and Tensor Charges of the Nucleon

Yorgo Sawaya, Christina Cocuzza, Gregory Matousek, Matthew McEneaney et autres

We assess the impact of future measurements of dihadron production in semi-inclusive deep-inelastic scattering from the CLAS12 and proposed SoLID experiments at Jefferson Lab, as well as from the ePIC experiment at the future Electron-Ion Collider (EIC), on the transversity parton distribution …

AI-Assisted Object Condensation Clustering for Calorimeter Shower Reconstruction at CLAS12

Gregory Matousek, A. Vossen

Several nuclear physics studies using the CLAS12 detector rely on the accurate reconstruction of neutrons and photons from its forward angle calorimeter system. These studies often place restrictive cuts when measuring neutral particles due to an overabundance of false clusters created by …

Semi-inclusive deep-inelastic scattering with CLAS12 at JLab

Gregory Matousek

Semi-Inclusive Deep Inelastic Scattering (SIDIS) is a powerful method for studying transverse momentum-dependent parton distribution functions (TMDs) and fragmentation functions (FFs). This paper reviews the ongoing SIDIS program using the CLAS12 spectrometer at Jefferson Lab, which enables precise, multidimensional measurements of cross …

Measuring Transversity in Di-Hadron Correlations with the ePIC Detector

Seth Reiman, Gregory Matousek

Transversity is the least understood of the three Parton Distribution Functions (PDFs) that are used to describe the proton’s substruction in a collinear picture using dihadron fragmentation. The upcoming Electron-Ion Collider (EIC) being constructed at Brookhaven National Laboratory is expected to provide …

Photon classification with Gradient Boosted Trees at CLAS12

Gregory Matousek, A. Vossen

Abstract Dihadron semi-inclusive deep inelastic scattering (SIDIS) of 10.6 GeV longitudinally polarized electrons off the proton has been measured using the CLAS12 detector at Jefferson Lab. Two separate channels, π^+π^0 and π^-π^0, were analyzed, requiring the reconstruction of diphoton pairs. In this …

Dihadron semi-inclusive deep inelastic scattering (SIDIS) of 10.6 GeV longitudinally polarized electrons off the proton has been measured using the CLAS12 detector at Jefferson Lab. Two separate channels, $π^+π^0$ and $π^-π^0$, were analyzed, requiring the reconstruction of diphoton pairs. In this analysis, …

Artificial Intelligence for the Electron Ion Collider (AI4EIC)

C. Allaire, Roberto Ammendola, E. C. Aschenauer, Maximilian Balandat et autres

Abstract The Electron-Ion Collider (EIC), a state-of-the-art facility for studying the strong force, is expected to begin commissioning its first experiments in 2028. This is an opportune time for artificial intelligence (AI) to be included from the start at this facility and …

Scaling properties of exclusive vector meson production cross section from gluon saturation

Gregory Matousek, V. Khachatryan, Jinlong Zhang

It is already known from phenomenological studies that in exclusive deep-inelastic scattering off nuclei there appears to be a scaling behavior of vector meson production cross section in both nuclear mass number, $A$, and photon virtuality, $Q^{2}$, which is strongly modified due …

A Direct Detection Search for Hidden Sector New Particles in the 3-60 MeV Mass Range

A. Ahmidouch, S. Davis, A. Gasparian, Tyler J. Hague et autres

In our quest to understand the nature of dark matter and discover its non-gravitational interactions with ordinary matter, we propose an experiment using a \pbo ~calorimeter to search for or set new limits on the production rate of i) hidden sector particles …
