PolyMinHash: Efficient Area-Based MinHashing of Polygons for Approximate Nearest Neighbor Search Open

A. Subedi, S. Pokharel · 2025

Similarity searches are a critical task in data mining. As data sets grow larger, exact nearest neighbor searches quickly become unfeasible, leading to the adoption of approximate nearest neighbor (ANN) searches. ANN has been studied for t…

Measurement of the Parity-Violating Asymmetry in the N to $Δ$ Transition at Low $Q^2$ Open

D. Adhikari, Thamraa A. Alshayeb, D. Androić, David Armstrong, A. Asaturyan , et al. · 2025

We report the measurement of the parity-violating asymmetry in the N to $Δ$ transition via the $e^- + p \rightarrow e^- + Δ^+$ reaction at two different kinematic points with low four-momentum transfer Q$^2$. Measurements were made with in…

Molecular Insights into CO2 Sequestration in MOF-74 Open

A. Subedi, Bibhas Adhikari, Aabiskar Bhusal, Kapil Adhikari · 2024

Advancements in materials for efficient carbon sequestration are crucial in addressing the rising levels of CO₂. Metal Organic Frameworks (MOFs) have emerged as a key focus due to their high CO₂ absorption capacity and versatility. This st…

The Q high performance LH target Open

J. Brock, S. Covrig Dusa, J. Dunne, C. Keith, D. Meekins , et al. · 2023

A high-power liquid hydrogen target was built for the Jefferson Lab Q_weakexperiment, which measured the tiny parity-violating asymmetry in $\\vec{e}$ p scattering at an incident energy of 1.16 GeV, and a Q² = 0.025 G…

Measurement of the beam-normal single-spin asymmetry for elastic electron scattering from and Open

D. Androić, David Armstrong, A. Asaturyan, K. Bartlett, R. Beminiwattha , et al. · 2021

We report measurements of the parity-conserving beam-normal single-spin elastic scattering asymmetries $B_n$ on $^{12}$C and $^{27}$Al, obtained with an electron beam polarized transverse to its momentum direction. These measurements add a…

Precision Measurement of the Beam-Normal Single-Spin Asymmetry in Forward-Angle Elastic Electron-Proton Scattering Open

D. Androić, David Armstrong, A. Asaturyan, K. Bartlett, J. Beaufait , et al. · 2020

A beam-normal single-spin asymmetry generated in the scattering of transversely polarized electrons from unpolarized nucleons is an observable related to the imaginary part of the two-photon exchange process. We report a 2% precision measu…

Parity-violating inelastic electron-proton scattering at low above the resonance region Open

D. Androić, David Armstrong, A. Asaturyan, K. Bartlett, R. Beminiwattha , et al. · 2020

We report the measurement of the parity-violating asymmetry for the inelastic scattering of electrons from the proton, at Q2=0.082GeV2 and W=2.23 GeV, above the resonance region. The result AInel=−13.5±2.0(stat)±3.9(syst) ppm agrees with t…

<i>Q</i><sub>weak</sub>: First Direct Measurement of the Proton’s Weak Charge Open

D. Androić, David Armstrong, A. Asaturyan, T. Averett, J. Balewski , et al. · 2017

The Q[subscript weak] experiment, which took data at Jefferson Lab in the period 2010 - 2012, will precisely determine the weak charge of the proton by measuring the parity-violating asymmetry in elastic e-p scattering at 1.1 GeV using a l…

The tracking analysis in the Q-weak experiment Open

First results from the GlueX experiment Open

The GlueX Collaboration, H. Al Ghoul, E.G. Anassontzis, F. Barbosa, A. V. Barnes , et al. · 2016

© 2016 Author(s). The GlueX experiment at Jefferson Lab ran with its first commissioning beam in late 2014 and the spring of 2015. Data were collected on both plastic and liquid hydrogen targets, and much of the detector has been commissio…
