Since these rare production are far below the observable level in the Standard Model and other popular new physics models such as the minimal supersymmetric model, we find that, in the topcolor-assisted technicolor models, the Z＇ can give significant contributions to these processes, and with reasonable values of the parameters, the cross section cr can reach several tens of tb and may be detected at the eγ collisions.展开更多

This technique only gives time-of-flight of the fragments, consequently one obtains only one-dimension information of the fragment. In order to investigate the complete dynamics of ion-molecule collisions, it is necessary to develop a position-sensitive multi-hit detector system. The position information was obtained by using the wedge-and-strip anode with very good resolution.展开更多
