Isoscalar single-pion production in the region of Roper and d⁎(2380) resonances

Isoscalar single-pion production in the region of Roper and d⁎(2380) resonances

Exclusive measurements of the quasi-free pn→ppπ− and pp→ppπ0 reactions have been performed by means of pd collisions at Tp=1.2 GeV using the WASA detector setup at COSY. Total and differential cross sections have been obtained covering the energy region Tp=0.95–1.3 GeV (s=2.3–2.46 GeV), which includ...
