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.
