Strong Decay Models
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, 
. Since this corresponds to a 3P0
state, it is now generally referred to as the 3p0
decay model. This suggestion was developed and applied extensively by
Le Yaouanc et al. 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 pair is produced with 3S1
quantum numbers; this possibility however appears to
disagree with experiment.
