Angular distributions of the polarized photons and electron in the decays of the ${}^3{D}_3$ state of charmonium

Alex W. K. Mok, Cheuk-Ping Wong, Wai-Yu Sit

We calculate the combined angular distribution functions of the polarized photons (${\gamma }_1$ and ${\gamma }_2$) and electron ($e^{-}$) produced in the cascade process $\bar{p}p\to$ $^3D_…
