Ernest Henley and the shape of baryons
Alfons J. Buchmann
Calculations of pion-baryon couplings, baryon quadrupole and octupole moments, baryon spin and orbital angular momentum done in collaboration with Ernest Henley are reviewed. A com…
Quadrupole moments of baryons
A. J. Buchmann, E. M. Henley
Quadrupole moments of decuplet baryons and the octet-decuplet transition quadrupole moments are calculated using Morpurgo's general QCD parameterization method. Certain relations a…
Electromagnetic multipole moments of baryons
Alfons J. Buchmann
We calculate the charge quadrupole and magnetic octupole moments of baryons using a group theoretical approach based on broken SU(6) spin-flavor symmetry. The latter is an approxim…
Three quark currents and baryon spin
A. J. Buchmann, E. M. Henley
We show that three-quark axial currents as required by broken SU(6) spin-flavor symmetry reduce the quark spin contribution to proton spin from (one-quark axial current v…
Hyperquarks and bosonic preon bound states
Michael L. Schmid, Alfons J. Buchmann
In a model in which leptons, quarks, and the recently introduced hyperquarks are built up from two fundamental spin 1/2 preons, the standard model weak gauge bosons emerge as preon…
Metaspin and dirishonic dark matter
Alfons J. Buchmann, Michael L. Schmid
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 th…
