Baryon octupole moments
We report on a calculation of higher electromagnetic multipole moments of
baryons in a non-covariant quark model approach. The employed method is based
on the underlying spin-flavor symmetry of the strong interaction and its
breaking.We present results on magnetic octupole moments of decuplet baryons
and discuss their implications.Comment: 3 page
Metaspin and dirishonic dark matter
The antisymmetry requirement of rishon bound state wave functions suggests a
new rishon quantum number called M spin. From M spin conservation and the
Nussinov-Weingarten-Witten theorem we predict the existence of a stable
pseudoscalar dirishonic meson, called zeta, that is lighter than the lightest
neutrino. Its mass is estimated as m(zeta) = 10^{-9} eV. This particle could
make up the major part of cold dark matter in the Universe.Comment: 8 pages, 1 figur
