Threshold Studies at LEAR
Various thresholds for the production of stable particles can be reached with beams from LEAR (Table 1). At thresholds the new particles appear in the centre of mass (cm.) system with vanishing relative energy. For a long time they stay close to each other, so that there will be strong final-state interaction (f.s.i.). If this f.s.i. can be sorted out then we can get information about low-energy interactions of many interesting particle combinations which are not available so far1. A systematic comparison could be valuable for a better understanding of low-energy quark dynamics.
