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/$c$)$^{2}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.110167.v1/t1","@type":"Dataset","description":"Beam asymmetry $\\Sigma$ for the low $-t$ region where the horizontal error bars indicate the rms widths of the $t$...","name":"K+ Sigma Beam Asymmetry t-channel"},{"@id":"https://doi.org/10.17182/hepdata.110167.v1/t2","@type":"Dataset","description":"Average beam asymmetry $\\Sigma$ for the low $-u$ region where the uncertainty on $\\Sigma$ is the statistical and systematic (uncorrelated...","name":"K+ Sigma Beam Asymmetry u-channel"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1785913?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/110167"}],"inLanguage":"en","name":"Measurement of the Photon Beam Asymmetry in $\\vec{\\gamma} p\\to K^+\\Sigma^0$ at $E_{\\gamma} = 8.5$ GeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1785913?version=1","version":1}
