THE STRANGENESS RADIUS AND MAGNETIC MOMENT OF THE NUCLEON REVISITED #1
, 1995
"... We update Jaffe’s estimate of the strange isoscalar radius and magnetic moment of the nucleon. We make use of a recent dispersion–theoretical fit to the nucleon electromagnetic form factors and an improved description of symmetry breaking in the vector nonet. We find µs = −0.24 ± 0.03 n.m. and r2 s ..."

Just How Strange? Loops, Poles and the Strangeness Radius of the Nucleon
, 1993
"... We consider a simple model for the strangeness radius of the nucleon. The model is based on vector meson dominance (VMD) and ω −φ mixing in addition to a kaon cloud contribution. We find that the VMD contribution is similar in magnitude and of the same sign as the kaon contribution to the Sachs stra ..."

STRANGE MAGNETISM
, 1998
"... We present an analytic and parameterfree expression for the momentum dependence of the strange magnetic form factor of the nucleon G (s) M (Q2) and its corresponding radius which has been derived in Heavy Baryon Chiral Perturbation Theory. We also discuss a modelindependent relation between the is ..."

Charge, strangeness and radius of strangelets
, 2008
"... We investigate, at both zero and finite temperature, the properties of strangelets versus the electric charge Z and strangeness S. The strangelet radius is not a monotonic function of either charge or strangeness, and a minimum is reached in the (Z, S) plane. However, the thermodynamically stable st ..."

We evaluate the lightest current is the mean square strangeness radius, 〈r2 s OZIallowed contribution to 〈r2 s〉, arising from the kaon cloud, using dispersion relations. Drawing upon unitarity constraints as well as K + N s ..."

η − η ′ Photoproduction and the Axial Isoscalar Neutral Current Coupling
, 1995
"... We show that coherent η and η ′ photoproduction by means of the Primakoff Effect on the proton depends on the strange component of the neutral axial current coupling. We construct polarization asymmetries that are sensitive to this coupling through the γ −Z interference. The η ′ is not a Goldstone b ..."

Using heavy baryon chiral perturbation theory to one loop, we derive an analytic and parameter–free expression for the momentum dependence of the strange magnetic form factor of the nucleon G (s) M (Q 2) and its corresponding radius. This should be considered as a lower bound. We also derive a model ..."

Strangeness in the Nucleon on the LightCone
