Coupled-channel analysis of πππ and [formula omitted] final states from [formula omitted] annihilation at rest in hydrogen targets at three densities

Abstract

The spin-parity analysis of the reactions pp → π +π −π 0,K +K −π 0,K ±K 0π ∓ is performed in the context of an approach which solves the problems connected to the complexity of K + K − π 0 dynamics and to the number of partial waves involved in pp annihilation at rest. The preliminary results are presented.
