Measurement of the helicity asymmetry $E$ for the $γ p \to p π^{0}$ reaction in the resonance region

K. Chan, N. Zachariou, M. Bashkanov +9

The double-spin-polarization observable $E$ for $γ p \to p π^{0}$ has been measured with the CEBAF Large Acceptance Spectrometer (CLAS) at photon beam energies $E_{γ}$ …

First measurement of hard exclusive $π^{-} Δ^{++}$ electroproduction beam-spin asymmetries off the proton

S. Diehl, N. Trotta, K. Joo +142

The polarized cross section ratio $σ_{L T^{'}} / σ_{0}$ from hard exclusive $π^{-} Δ^{++}$ electroproduction off an unpolarized hydrogen target has been extracted based on beam-spin asym…

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…
