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.

A Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics

The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to cover the available parameter space for Weakly Interacting Massive Particles (WIMPs), while featuring extensive sensitivity to many alternative dark matter candidates. These detectors can also study neutrinos through neutrinoless double-beta decay and through a variety of astrophysical sources. A next-generation xenon-based detector will therefore be a true multi-purpose observatory to significantly advance particle physics, nuclear physics, astrophysics, solar physics, and cosmology. This review article presents the science cases for such a detector
