First measurement of polarized spin-density matrix elements and differential cross sections d $σ$ /d $t$ in $ω$ ~photoproduction off the proton for $2.7 < E_{γ} < 5.2$ GeV using CLAS at Jefferson Lab

T. Hu, Z. Akbar, V. Crede +147

We report on the differential cross sections d $σ$ /d $t$ , the unpolarized spin-density matrix elements $ρ_{00}^{0}$ , $ρ_{1 - 1}^{0}$ , Re\, $ρ_{10}^{0}$ , and the first extraction of the polari…

Horizontal 1 K refrigerator with novel loading mechanism for polarized solid targets

J. Brock, C. Carlin, D. Griffith +10

We describe a helium evaporation refrigerator used to cool dynamically polarized proton and deuteron targets for electron-scattering experiments using the CEBAF Large Acceptance Sp…

First CLAS12 measurement of DVCS beam-spin asymmetries in the extended valence region

CLAS Collaboration, G. Christiaens, M. Defurne +168

Deeply virtual Compton scattering (DVCS) allows one to probe Generalized Parton Distributions (GPDs) describing the 3D structure of the nucleon. We report the first measurement of…
