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.
