Measurement of the photon beam asymmetry in at GeV
Abstract
We report measurements of the photon beam asymmetry $$\Sigma$$ for the reaction $$\vec{\gamma} p\to K^+\Sigma^0$$(1193) using the GlueX spectrometer in Hall D at Jefferson Lab. Data were collected using a linearly polarized photon beam in the energy range of 8.2-8.8 GeV incident on a liquid hydrogen target. The beam asymmetry $$\Sigma$$ was measured as a function of the Mandelstam variable $$t$$, and a single value of $$\Sigma$$ was extracted for events produced in the $$u$$-channel. These are the first exclusive measurements of the photon beam asymmetry $$\Sigma$$ for the reaction in this energy range. For the $$t$$-channel, the measured beam asymmetry is close to unity over the $$t$$-range studied, $-t=(0.1-1.4)~$(GeV/$$c$$)$$^{2}$$, with an average value of $$\Sigma = 1.00\pm 0.05$$. This agrees with theoretical models that describe the reaction via the natural-parity exchange of the $$K^{*}$$(892) Regge trajectory. A value of $$\Sigma = 0.41 \pm 0.09$$ is obtained for the $$u$$-channel integrated up to $-u=2.0$~(GeV/$$c$$)$$^{2}$$.
