Studies of the structure of excited baryons are key factors to the N* program at Jefferson Lab
(JLab). Within the first year of data taking with the Hall B CLAS12 detector following the 12 …

The low-energy spectrum and scattering of two-nucleon systems are studied with lattice
quantum chromodynamics using a variational approach. A wide range of interpolating …

A bstract Simulating the κ (800) on the lattice is a challenging task that starts to become
feasible due to the rapid progress in recent-years lattice QCD calculations. As the reso …

At the TeV scale, low-energy precision observations of neutron characteristics provide
unique probes of novel physics. Precision studies of neutron decay observables are …

A coupled-channel S-and P-wave next-to-leading order chiral-unitary approach for
strangeness S=− 1 meson-baryon scattering is extended to include the new data from the …

A bstract We study theoretically the effects of finite volume for ππ scattering in order to
extract physical observables for infinite volume from lattice QCD. We compare three different …

Exclusive electroproduction reactions provide an access to the structure of excited baryons.
To extract electroproduction multipoles encoding this information, the Jülich–Bonn …

In this thesis, the Dyson-Schwinger-Bethe-Salpeter formalism is investigated and used to
study the meson spectrum at zero temperature, as well as the chiral phase transition in finite …

The exploration of nucleon structure and electromagnetic transitions from ground-state to
excited-state is a cornerstone of nuclear physics research. Meson electro-production …

We study the dependence of the $ D_ {s0}(2317) $ mass on the light quark mass through the
analysis of data from QCD lattice simulations. Combining HH $\chi $ PT and model selection …
