Beam-spin asymmetries from semi-inclusive pion electroproduction

CLAS Collaboration, W. Gohn, H. Avakian +2

We have measured the moment $A_{LU}^{\sin \varphi }$ corresponding to the polarized electron beam-spin asymmetry in SIDIS. $A_{LU}^{\sin \varphi }$ is a twist-3 quantity providing information abou…
