A partial-wave analysis of the pure isospin I = 1 reactions K−n→Σ−π0 and K−n→Σ0π− in the center-of-mass energy range 1850-2150 MeV is reported. The decay mode Σ(2030)→Σπ is observed with a branching ratio xr given by eiφ(xexr)12 = −0.085±0.02, where xe is the elasticity and φ is the relative phase of the resonance with the phase of Σ(1765) taken to be zero.

We have studied the process p¯p into π+X− using wire spark chambers. The data cover the angular range of cosθp¯π+* between 0.96 and 1.0 at several incident momenta between 1 and 2 GeVc. The reaction p¯p→π+ρ− was observed with (dσdΩ)* of the order of 100 μb/sr at several momenta.

Elastic scattering of p¯ on p has been studied for cosθc.m. between -0.88 and -1.0 and Plab(p¯) between 0.70 and 2.16 GeV/c. The momentum dependence of the cross section shows a sharp dip at 0.9 GeV/c and a broad peaking around 1.4 GeV/c. The possibility of the peak resulting from direct formation of boson resonances has been studied. Alternatively, a diffraction model agrees qualitatively with our data and other elastic data at different angles.
