Correlations in the final states ppπ+π?π+π? and ppπ+π?π+π?π+π? from 28.5 GeV/c pp collisions

We compare various invariant mass and angular distributions from the final states ppπ⁺π^?π⁺π^? and ppπ⁺π^?π⁺π^?π⁺π^? with the predictions of two models. The essential input to these models is the correct single-particle distributions with energy and momentum conservation constraints taken into account. The data is from 28.5 GeV/c pp interactions in the BNL 80-inch bubble chamber. Substantial agreement between the data and the models is obtained inferring that the kinematic constraints of energy and momentum conservation play a strong role in determining correlations between particles in these high multiplicity final states.
