Strangeness contents in the nucleon — •T. Watabe, H.-C. Kim, and K. Goeke — Institut f. Theoretische Physik II, Ruhr–Univ. Bochum

We investigate strangeness contents in the nucleon using the chiral quark soliton model (also called Nambu–Jona-Lasinio soliton model). We present the electromagnetic and axial strange form factors and discuss them. We found that the electromagnetic properties of the neutron are sensitive to the strangeness via a kaonic cloud. We show also the mean squared radii and the magnetic moments.
