abstract = {Exclusive measurements of the quasi-free $pp \to
pp\pi^+\pi^-$ reaction have been performed by means of $pd$
collisions at $T_p$ = 1.2 GeV using the WASA detector setup
at COSY. Total and differential cross sections have been
obtained covering the energy region $T_p = 1.08 - 1.36$ GeV
($\sqrt s$ = 2.35 - 2.46 GeV), which includes the regions of
$N^*(1440)$ and $\Delta(1232)\Delta(1232)$ resonance
excitations. Calculations describing these excitations by
$t$-channel meson exchange are at variance with experimental
differential cross sections and underpredict substantially
the measured total cross section. An isotensor $\Delta N$
dibaryon resonance with $I(J^P) = 2(1^+)$ produced
associatedly with a pion is able to overcome these
deficiencies. Such a dibaryon was predicted by Dyson and
Xuong and more recently calculated by Gal and Garcilazo.},
