− | 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.
