    "abstract": "The tensor analyzing power of the process $d + p \\to d + X$, for forward\ndeuteron scattering in the momentum interval 3.7 to 9 GeV/c, is studied in the\nframework of $\\omega$ exchange in an algebraic collective model for the\nelectroexcitation of nucleon resonances. We point out a special sensitivity of\nthe tensor analyzing power to the isoscalar longitudinal form factor of the\nRoper resonance excitation. The main argument is that the $S_{11}(1535)$,\n$D_{13}(1520)$ and $S_{11}(1650)$ resonances have only isovector longitudinal\nform factors. It is the longitudinal form factor of the Roper excitation, which\nplays an important role in the $t-$dependence of the tensor analyzing power. We\ndiscuss possible evidence of swelling of hadrons with increasing excitation\nenergy.",
