Beam Spin Asymmetry Measurements of Deeply Virtual $π^0$ Production with CLAS12

A. Kim, S. Diehl, K. Joo, V. Kubarovsky et autres

The new experimental measurements of beam spin asymmetry were performed for the deeply virtual exclusive $π^0$ production in a wide kinematic region with the photon virtualities $Q^2$ up to 8 GeV$^2$ and the Bjorken scaling variable $x_B$ in the valence regime. The …

First CLAS12 Measurement of Deeply Virtual Compton Scattering Beam-Spin Asymmetries in the Extended Valence Region

G. Christiaens, M. Defurne, D. Sokhan, Patrick Achenbach et autres

Deeply virtual Compton scattering (DVCS) allows one to probe generalized parton distributions describing the 3D structure of the nucleon. We report the first measurement of the DVCS beam-spin asymmetry using the CLAS12 spectrometer with a 10.2 and 10.6 GeV electron beam scattering …

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

CLAS Collaboration, G. Christiaens, M. Defurne, D. Sokhan et autres

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 the DVCS beam-spin asymmetry using the CLAS12 spectrometer with a 10.2 and 10.6 GeV electron beam …

First observation of correlations between spin and transverse momenta in back-to-back dihadron production at CLAS12

H. Avakian, T. B. Hayward, A.M. Kotzinian, W. R. Armstrong et autres

We report the first measurements of deep inelastic scattering spin-dependent azimuthal asymmetries in back-to-back dihadron electroproduction, where two hadrons are produced in opposite hemispheres along the z-axis in the center-of-mass frame, with the first hadron produced in the current-fragmentation region and the …

Exclusive $\pi^{-}$ Electroproduction off the Neutron in Deuterium in the Resonance Region

Yining Tian, R. W. Gothe, V. I. Mokeev, G. Hollis et autres

New results for the exclusive and quasi-free cross sections off neutrons bound in deuterium ${\gamma}_vn(p) \rightarrow p{\pi}^{-} (p)$ are presented over a wide final state hadron angle range with a kinematic coverage of the invariant mass ($W$) up to 1.825 GeV and …
