  A model-independent irreducible tensor formalism which has been developed
earlier to analyze measurements of $\vec{p}\vec{p}\to pp \pi^\circ$, is
extended to present a theoretical discussion of $\vec{p}\vec{p}\to pp \omega$
and the polarization of $\omega$ in $pp\to pp \vec{\omega}$. The recent
measurement of unpolarized differential cross section for $pp\to pp \omega$ is
analyzed using this theoretical formalism.
