Abstract/Description: Hadron spectroscopy is used to acquire more information on the quark-gluon interactions and existence of excited hadrons. The photoproduction reaction $\gamma p\to K^0\Sigma^+$ using data from the "g12" experiment of CLAS at Jefferson Lab has been analyzed. This reaction is underexplored among the isospin-related $K\Sigma$ channels. In the g12 experiment, photons ranging in energy from 1.1 to 5.4 GeV were incident on a liquid hydrogen target and the differential cross section was extracted. Events which contained the proton and three-pion final state ($p\pi^+\pi^-\pi^0$) were selected. Various cuts and an event-based quality factor determination was used for background subtraction. Monte Carlo simulations were then preformed to determine acceptance corrections for the cross section. These results will have a significant impact on partial wave analysis that aims on extracting nucleon resonances from photoproduction data.
