Filling up the Two-Body Partial Decay Width of P-Wave Charmonia with the Color Octet Contribution

Abstract

The importance of the color octet component in P-wave charmonia is discussed in the context of exclusive decay processes. It is vital to include this contribution already at the level of the two-body decay channels. The \pi \pi and proton-antiproton channels are used as examples.
