Quark-gluon correlations in the neutron were probed by performing precision measurements of (d[sub]2)[sup]n and (g[sub]2)[sup]n.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 2180708The EG4 group of experiments is devoted to precision measurements of single and double spin observables in reactions on polarized neutrons, including the small-angle GDH sum rule.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 2180452At the MAMI accelerator in the A1 Collaboration we plan to perform a test experiment of pion electro-production in the Roper region by measuring a set of double polarization observables. We report on the basic properties of the planned experimental setup.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 2198116In this paper we deal with pion electroproduction on nucleons in the region of the Roper resonance. A specific class of quark models is used, and a K-matrix formalism is applied to them in order to derive the scattering as well as electroproduction amplitudes including their phases.
