Theory models predict a total of 44 cascade states below 2.5 GeV. Currently, there are only six Ξ states that have at least a three-star rating in the PDG, with the production mechanism of these states still remaining mostly elusive. The goal of the “Very Strange” project is to study the quasi-real photoproduction of cascades to search for missing and new states. The new data from Jefferson...

As nuclear physics moves solidly into the 21st century, we are in need of high-coverage, high-rate detection of events. The Solenoidal Large Intensity Device SoLID seeks to fill that need for a large-acceptance, high-luminosity device in Hall A of Jefferson Lab. In keeping with the theme of modernization, the SoLID collaboration has sought to bring cutting-edge technologies and methods into...

The MOLLER (Measurement Of Lepton-Lepton Electroweak Reaction) experiment is an ultra-precise measurement of the parity-violating asymmetry, APV, in purely leptonic Møller interactions between longitudinally polarized electrons and unpolarized electrons in a liquid hydrogen target at momentum transfer Q2 < mZ. The APV measurement is predicted to be ~33ppb and will be measured to an overall...

Inclusive electron scattering experiments performed at JLab have been a powerful tool to probe nuclear structure. Mean field theory has been a very accurate model at predicting a variety of properties of the nucleus. However, it fails to predict the distribution of high momentum nucleons within the nucleus. To answer this, the SRC picture points to multi-nucleon Short-Range Correlations (SRCs)...

The reconciliation of observable properties of hadrons with the fundamentals of QCD has remained a persisting challenge in modern nuclear theory. Lattice QCD is a numerical method that bridges the gap between first-principles QCD and observables in nuclear systems in the strong coupling regime. By casting a scattering problem onto a finite, discretized spacetime lattice, one obtains a...

The deuteron electro-disintegration $D(e,e'p)n$ experiment aims to measure D(e,e'p)n cross sections at high $Q^2$, $x_{Bj}~1$, and missing momenta $p_m>600$ MeV/c with great statistical precision. To obtain a greater understanding of the strong nuclear force, we must probe the nucleus at sub-fermi distances where the nucleons overlap. In this region, the nucleon-nucleon (NN) interaction...

The PrimEx experiment at Jefferson Lab aims to extract the η radiative decay width via the Primakoff effect. This process can be seen as the inverse process of the decay of the η-meson into two photons. The experiment collected data on liquid helium target in three different phases, 2019, 2021 and 2022 utilizing the GlueX detector in Hall-D. By extracting a high precision measurement of the...

Vector meson photoproduction observables may provide insight into the internal structure of the nucleon. This work aims to extend world data on determinations of differential cross section for rho^0 photoproduction off protons. The analysis is performed using data from by the CLAS6 detector during the g12 run period for beam energies between 1.15 and 5.45 GeV and -t between 0 and 5 GeV^2.

to support Nuclear and High Energy Physics experiments. Its purpose is to extract physics directly from data in the most complete manner possible. Generative models such GANs are employed to capture the full correlations between particles in the final state of nuclear
reactions. This many-fold...
