Beam-spin asymmetry $\mathbf{\Sigma }$ for ${\Sigma }^{-}$ hyperon photoproduction off the neutron

Nicholas Zachariou, Edwin Munevar, Barry Berman +8

We report a new measurement of the beam-spin asymmetry $\mathbf{\Sigma }$ for the $\vec{\gamma }n\to K^{+}{\Sigma }^{-}$ reaction using quasi-free neutrons in a liquid-deuterium target. The new…
