DOIAbstract
International audienceThe COMPASS collaboration has collected the currently largest data set on diffractively produced π-π-π+ final states using a negative pion beam of 190 GeV/c momentum impinging on a stationary proton target. This data set allows for a systematic partial-wave analysis in 100 bins of three-pion mass, 0.5<m3π<2.5 GeV/c2, and in 11 bins of the reduced four-momentum transfer squared, 0.1<t′<1.0 (GeV/c)2. This two-dimensional analysis offers sensitivity to genuine one-step resonance production, i.e. the production of a state followed by its decay, as well as to more complex dynamical effects in nonresonant 3π production. In this paper, we present detailed studies on selected 3π partial waves with JPC=0-+, 1++, 2-+, 2++, an...
