CLAS Electro-Omega Production
Electroproduction of omega (783) mesons from a proton target has been measured at CLAS in a search for so called ''missing'' baryon resonances. Scattered electrons were measured in coincidence with the recoiling proton and a pi{sup +} from the omega decay. Missing mass techniques were applied to identify the outgoing omega and to reduce the contributions of rho (770) and 2 pi final states. The resulting ep missing mass distributions clearing show an omega peak superimposed on a predominantly 3-pion phase space. Preliminary analysis indicates that t distributions monotonically decrease for W>2 GeV, as expected from pi-exchange and diffractive processes but for 1.8 GeV<W<2 GeV the distributions are non monotonically decreasing.
