ω production inppcollisions

Abstract

A model-independent irreducible tensor formalism that was developed earlier to analyze measurements of $\stackrel{\ensuremath{\rightarrow}}{p}\stackrel{\ensuremath{\rightarrow}}{p}\ensuremath{\rightarrow}\mathit{pp}{\ensuremath{\pi}}^{\ifmmode^\circ\else\textdegree\fi{}}$ is extended to present a theoretical discussion of $\stackrel{\ensuremath{\rightarrow}}{p}\stackrel{\ensuremath{\rightarrow}}{p}\ensuremath{\rightarrow}pp\ensuremath{\omega}$ and of \ensuremath{\omega} polarization in $\mathit{pp}\ensuremath{\rightarrow}\mathit{pp}\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\omega}}$ and in $p\stackrel{\ensuremath{\rightarrow}}{p}\ensuremath{\rightarrow}pp\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\omega}}$. The recent measurement of an unpolarized differential cross section for $pp\ensuremath{\rightarrow}pp\ensuremath{\omega}$ is analyzed by use of this theoretical formalism.
