K^*0 Photoproduction off the proton at CLAS

Abstract

We report here differential cross sections for the reaction ${\hat{I}}^{3}p\to K^{\ast 0}\hat{I}{\pounds }^{+}$ for the first time with high statistics. The measurements were done using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. Data were taken at 3.115 GeV electron beam energy using tagged photons incident upon a liquid hydrogen target. In addition, our analysis provides information about nucleon resonances and their couplings to $K^{\ast }$ decay. Our data will be used to test predictions of theoretical models of K${}^{\ast }$ production, and to provide constraints on the $K^{\ast }\hat{I}\pounds N$ coupling constant used in these models.
