Letter of Intent: Open Charm at JLab with the sPHENIX MAPS tracker Open
We propose a physics program at JLab with CLAS12 focusing on open-charm measurements, aiming to complement and expand current studies of $J/ψ$ at (sub) threshold. This program will aid us in elucidating the $J/ψ$ production mechanisms, whi…

Estimating the potential of SWGO to measure the composition-dependent behaviour of the CR anisotropy Open
Current cosmic ray anisotropy experiments have shown a significant swing in both the direction and the amplitude of the dipole at energies around tens of TeV. Due to the charged nature of these particles, and the presence of magnetic field…

An update on site search activities for SWGO Open
The Southern Wide-field Gamma-ray Observatory (SWGO) is a project by scientists and engineers from 14 countries and 78 institutions to design and build the first wide-field, ground-based gamma-ray observatory in the Southern Hemisphere, wi…

Dark Matter searches in Dwarf Galaxies with the Southern Wide-field Gamma-ray Observatory Open
Dark matter is thought to make up most of the matter density of the Universe, yet its true nature remains uncertain. Among dark matter theories, Weakly Interacting Massive Particles (WIMPs) are a prominent candidate for dark matter because…

Manufacture Details of a SWGO Double-Layer Tank Design - Water Cherenkov Detector Prototype Open
Water-Cherenkov detectors (WCD) have been manufactured in Australia by the company AQUAMATE as part of the R&D activities for SWGO. They consist of a steel tank frame with a bladder on its interior satisfying the SWGO double-layer tank des…

Status of the SWGO air shower reconstruction using a template-based likelihood method Open
The Southern Wide-field Gamma-ray Observatory (SWGO) is a proposed facility for ground-based gamma-ray astronomy. It will consist of an array of water Cherenkov detectors to detect astrophysical gamma-rays mainly in the range of hundreds o…

Wavelength-shifting light traps for SWGO and other applications Open
Wavelength-shifting (WLS) materials contain molecules that absorb light and reemit at longer wavelengths. They can be used for light detection because they provide a large effective area for low cost and they are able to efficiently trap a…

Measurement of unpolarized semi-inclusive pi+ electroproduction off the proton Open
Semi-inclusive pi+ electroproduction on protons has been measured with the CLAS detector at Jefferson Lab. The measurement was performed on a liquid-hydrogen target using a 5.75 GeV electron beam. The complete five-fold differential cross …

NPF: mirror development in Chile Open
In the era of high-angular resolution astronomical instrumentation, where long and very long baseline interferometers (constituted by many, $\sim$ 20 or more, telescopes) are expected to work not only in the millimeter and submillimeter do…

Search for the Theta+ pentaquark in the gamma d -> Lambda n K+ reaction measured with CLAS Open
For the first time, the reaction gamma d -> Lambda n K+ has been analyzed in order to search for the exotic pentaquark baryon Theta+(1540). The data were taken at Jefferson Lab, using the Hall-B tagged-photon beam of energy between 0.8 …
