For a decaying particle with spin = 0 ( D mesons ):
the decay rate can be written as :
Where M is the decaying particle mass, M is the matrix element that keeps into account the dynamics of the process,
m212 and m213 are the square masses of the pairs of the particles produced in the decay. One can expect that, without any
resonant states like the following:
the yield on the Dalitz Plot surface should be uniform.
Otherwise, the presence of any structure on the Dalitz Plot can
be the signal of the contribution of resonant amplitude in the
Dalitz Plot and its kinematic limits
