The Ο1β(1600), a JPC=1β+ exotic meson has been observed by
experiments using pion beams. Theorists predict that photon beams could produce
gluonic hybrid mesons, of which the Ο1β(1600) is a candidate, at enhanced
levels relative to pion beams. The g12 rungroup at Jefferson Lab's CEBAF Large
Acceptance Spectrometer (CLAS) has recently acquired a large photoproduction
dataset, using a liquid hydrogen target and tagged photons from a 5.71 GeV
electron beam. A partial-wave analysis of 502K Ξ³pβΟ+Ο+Οβn
events selected from the g12 dataset has been performed, and preliminary fit
results show strong evidence for well-known states such as the a1β(1260),
a2β(1320), and Ο2β(1670). However, we observe no evidence for the
production of the Ο1β(1600) in either the partial-wave intensities or the
relative complex phase between the 1β+ and the 2β+ (corresponding to
the Ο2β) partial waves.Comment: Proceedings from the XIV International Conference on Hadron
