Tensor polarization of $\omega$ produced at threshold in $p-p$ collisions

Abstract

It is shown that the dominant decay mode of $\vec{\omega }\to {\pi }^{+}{\pi }^{-}{\pi }^0$ can be employed to determine the Fano statistical tensor $t_0^2$ of $\vec{\omega }$ with respect to the quantization axis normal to the decay plane. In $pp\to pp\vec{\omega }$ one can choose decay planes with different orientations for a given $\omega$ direction, $\theta$. By choosing three different experimentally convenient orientations of the decay planes for the same $\theta$, one may determine empirically the $t_0^2$ and $t_{\pm 2}^2$ characterising the tensor polarization of $\omega$ in the Transverse Frame for $pp\to pp\vec{\omega }$.
