Query: The $\omega\sigma\gamma$-vertex in light cone QCD sum rules   We investigate the $\omega\sigma\gamma$-vertex and estimate the coupling
constant g$_{\omega\sigma\gamma}$ in the framework of the light cone QCD sum
rules. We compare our result with the values of this coupling constant deduced
from a phenomenological analysis of $\omega\to\pi\pi\gamma$ decays.
