Hadronische Reaktionen am Deuteron im $\Delta$-Resonanzbereich
In the present work we study hadronic reactions on a deuteron sarget in the $\Delta$(1232) resonance energy region. In particular we investigate $\pi^{+}$d scattering, d(p, n) and d($^{3}$He, t) charge exchange reactions, and the two pion productionn + p $\rightarrow$ d($\pi$ $\pi$). These processes...

In the present work we study hadronic reactions on a deuteron sarget in the $\Delta$(1232) resonance energy region. In particular we investigate $\pi^{+}$d scattering, d(p, n) and d($^{3}$He, t) charge exchange reactions, and the two pion productionn + p $\rightarrow$ d($\pi$ $\pi$). These processes are shown to be influenced by residual interactions within the excited $\Delta$N and $\Delta \Delta$ intermediate states, respectively. A new theoretical approach based on a couplecl cha.nnel formalism is applied in order to ensure a proper dynamical treatment of the $\Delta$ degrees of freedom. For the $\Delta$N and $\Delta \Delta$ interaction potentials, we adopt a meson exchange model with $\pi, \rho, \omega$, and $\sigma$ exchange taken into account. Various observables such as inclusive and exclusive cross sections, angular distributions, and polarization parameters are caiculated. An overall good agreement with available experimental data and thus a comprehensive understanding of the $\Delta$ excitation in the deuteron is achieved. |
