Research Focus

Dr. Strauch's research focuses on the study of the structure and interaction of baryons.  It includes high-precision, polarized and unpolarized, electro- and photoproduction experiments that will pin down present problems in nuclear physics. In particular, (1) the Muon Scattering Experiment (MUSE) at the Paul Scherrer Institut in Switzerland will measure elastic muon-proton and electron-proton scattering. MUSE will provide tight constraints on new physics, shed more light on the so-called proton-radius puzzle, and provide invaluable information on radiative corrections as well as two-photon exchange effects in lepton-scattering processes. (2)  Complete and mostly complete meson-photoproduction measurements at the Thomas Jefferson National Accelerator Facility (JLab) in Virginia will address in an almost model-independent way lingering problems in baryon spectroscopy and verify the SU(6)xO(3) three-quark baryon structure. (3) The properties of hadrons are modified in the medium as a consequence of the partial restoration of chiral symmetry or many-body effects. The bound proton electromagnetic form factors may be changed compared to those in the vacuum as revealed for the first time by the group's earlier measurements. New experiments on nuclear targets at MAMI and JLab, respectively, will confirm or refute these results. The observations of such phenomena are potentially transformative in the way we view hadrons and their interactions in nuclear matter.

Challenge the conventional. Create the exceptional. No Limits.
