Extraction of the pion-nucleon sigma-term from the spectrum of exotic baryons
P. Schweitzer
The pion nucleon sigma-term is extracted on the basis of the soliton picture of the nucleon from the mass spectrum of usual and the recently observed exotic baryons, assuming that…

Azimuthal single spin asymmetries in SIDIS in the light of chiral symmetry breaking
P. Schweitzer, A. Bacchetta
An attempt is made to understand the z-dependence of the azimuthal single spin asymmetries observed by the HERMES collaboration in terms of chiral models based on effective quark a…

Quark distribution functions in the chiral quark-soliton model: cancellation of quantum anomalies
K. Goeke, P. V. Pobylitsa, M. V. Polyakov +2
In the framework of the chiral quark-soliton model of the nucleon we investigate the properties of the polarized quark distribution. In particular we analyse the so called anomalou…
