| − | Attempts at modeling strong decays date from 1969,
| |
| − | when Micu suggested
| |
| − | that hadron decay proceeds through $q\bar q$ pair production with vacuum
| |
| − | quantum numbers, <math>J^{PC} = 0^{++}</math>. Since this corresponds to a <sup>3</sup>P<sub>0</sub>
| |
| − | <math>q\bar q</math> state, it is now generally referred to as the 3p0
| |
| − | decay model. This suggestion was developed and applied extensively by
| |
| − | Le Yaouanc <i>et al.</i> in the 1970s.
| |
| − | Studies of hadron decays using the 3p0 model
| |
| − | have been
| |
| − | concerned almost exclusively with numerical predictions, and have not led to
| |
| − | any fundamental modifications to the original model.
| |
| − | Recent studies have considered changes in the spatial
| |
| − | dependence of the pair production amplitude as a function of
| |
| − | quark coordinates
| |
| − | but the fundamental decay mechanism is usually not
| |
| − | addressed; this is widely believed to be a nonperturbative process,
| |
| − | involving ``flux tube breaking".
| |
| − | There have been some studies of the decay
| |
| − | mechanism which consider an alternative phenomenological
| |
| − | model in which the <math>q\bar q</math> pair is produced with <sup>3</sup>S<sub>1</sub>
| |
| − | quantum numbers; this possibility however appears to
| |
| − | disagree with experiment.
