Hadronische Reaktionen am Deuteron im #DELTA#-Resonanzbereich

In the present work we study hadronic reactions on a deuteron target in the #DELTA#(1232) resonance energy region. In particular we investigate #pi#"+d scattering, d(p,n) and d("3He,t) charge exchange reactions, and the two pion production n + p #-># 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 coupled channel 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 calculated. An overall good agreement with available experimental data and thus a comprehensive understanding of the #DELTA# excitation in the deuteron is achieved.
