%X Exclusive measurements of the quasifree pp→ppπ+π− reaction have been carried out at WASA@COSY by means of pd collisions at Tp=1.2  GeV. Total and differential cross sections have been extracted covering the energy region Tp=1.08–1.36  GeV, which is the region of N∗(1440) and Δ(1232)Δ(1232) resonance excitations. Calculations describing these excitations by t-channel meson exchange are at variance with the measured differential cross sections and underpredict substantially the experimental total cross section. An isotensor ΔN dibaryon resonance with I(JP)=2(1+) produced associatedly with a pion is able to overcome these deficiencies.
