✦ Synopsis

The importance of iucluding colour octet contributions in describing decay and production of quarkouium states is briefly discussed for two cases : the radiative decays of the T and the production of J/q5 in the inclusive B decays. It is shown how information ou the non-perturbative matrix elements can be obtained by comparing the theoretical expressions computed at next-to-leading order in n,? with the experimental data.

In inclusive P-wave charmonium decay, to cancel infrared divergence in the colour singlet contribution requires the inclusion of the colour octet which becomes degenerate with the former in the infrared limit. In the corresponding exclusive decay, such an infrared divergence does not exist. On this
