| Popis: | We discuss the analysis of possible 3-jet events in e + e − annihilation and elsewhere. If one selects events with low thrust, the particles recoiling away from the thrust axis should appear as a pair of back-to-back jets in their centre-of-mass system. The angular distributions of such jets are very different in the case of vector gluon bremsstrahlung from what they would be for scalar gluons, or for the 3-gluon decay of a heavy quarkonium resonence. We outline a similar analysis of 3-jet events in photoproduction. |
