$\Delta$ excitation in antiproton-deutron annihilation

The \Delta-excitation in \overline{p}d annihilation at rest was studied. The annihilation amplitude from the statistical model and the \pi N amplitude from the resonance model were adopted in our calculations. We analyze the invariant mass of the \pi^+p and \pi^-p systems selecting the protons with momenta above 400 MeV/c and with respect to the different final reaction channels. Our model reproduces reasonably the experimental data
