Light Vector Meson Photoproduction off of $^1$H at Jefferson Lab and $\rho$-$\omega$ Interference in the Leptonic Decay Channel

ORAL

Abstract

Recent studies of light vector meson production in heavy nuclear targets has generated interest in $\rho$-$\omega$ interference in the leptonic decay channel. An experimental study of the elementary process provides valuable input for theoretical models and calculations. In experiment E04-005, high statistics photoproduction data has been taken in Jefferson Lab's CLAS detector with tagged photon energies up to 5 GeV incident on a LH$_2$ target. Preliminary results of the $e^{+}e^{-}$ decay channel, with emphasis on the $\rho$-$\omega$ interference region, will be shown and compared to similar experimental data of photoproduction off of heavier nuclear targets ($^2$H to Pb) from Jefferson Lab experiment E01-112.
