In this case, the Dalitz plot will show a non-uniform distribution, with a peak around the mass of the resonant decay.

In a traditional Dalitz plot, the axes of the plot are the squares of the invariant masses of two pairs of the decay products.

Dalitz plots play a central role in the discovery of new particles, in current high-energy physics experiments, and are being used in the search for the Higgs boson.

In addition he is known for other key developments in particle physics: the Dalitz plot and the Castillejo-Dalitz-Dyson (CDD) poles.

A specific form of a four-particle Dalitz plot (for non-relativistic kinematics), which is based on a tetrahedral coordinate system, was first applied to study the few-body dynamics in atomic four-body fragmentation processes.

In this way, the Dalitz plot provides an excellent tool for studying the dynamics of three-body decays and they are one of the tools applied in the search for the Higgs boson.

The Dalitz plot is a ternary plot often used in particle physics to represent the relative frequency of various (kinematically distinct) manners in which the products of certain (otherwise similar) three-body decays may move apart.
