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 …

Photoproduction of mesons is an excellent tool for the study of nucleon resonances.
Complementary to pion induced reactions, photoproduction on the free proton contributes to …

Hadrons in lattice QCD are usually created employing smeared interpolators. We introduce
a new quark smearing that allows us to maintain small statistical errors and good overlaps of …

Within the non-relativistic potential scattering theory, we derive a generalized version of the
Lüscher formula, which includes three-particle inelastic channels. Faddeev equations in a …

New SAPHIR p (γ, K+) Λ total cross section data show a resonance structure at a total cm
energy around 1900 MeV. We investigate this feature with an isobar model and find that the …

We present a nucleon resonance analysis by simultaneously considering all pion-and
photon-induced experimental data on the final states γ N, π N, 2 π N, η N, K Λ, K Σ, and ω N …

We present a nucleon resonance analysis by simultaneously considering all pion-and
photon-induced experimental data on the final states γ N, π N, 2 π N, η N, K Λ, K Σ, and ω N …

We present results of our numerical calculation of the mass spectrum for isospin one-half
and spin one-half nonstrange baryons, ie, the ground and excited states of the nucleon, in …

We present the first results for the masses of positive and negative parity excited baryons
calculated in lattice QCD using an O (a 2)-improved gluon action and a fat-link irrelevant …

Using the constrained-curve fitting method and overlap fermions with the lowest pion mass
at 180 MeV, we observe that the masses of the first positive and negative parity excited …
