Analysis of Radiative Decay of Eta Meson in CLAS

ORAL

Abstract

The Light Meson Decay (LMD) program at CLAS was formed to analyze decays of light mesons produced in the photoproduction reaction $\gamma$p$\to$pX, where X = $\pi^0,\eta,\omega,\eta',$ and $\phi$. While the two photon decays of the light mesons are described by the triangle anomaly, we focus on the radiative decay of $\eta\to\pi^+\pi^-\gamma$ which proceeds from the less understood box anomaly. The data analyzed was taken during the g11a run period at Jefferson Lab. The decay photon energy distribution will be presented and compared to theory prediction.
