Photon-Neutrino Interactions
G. Karl, V. Novikov
We discuss the interaction of photons with neutrinos including two lepton loops. The parity violation in the gamma-nu to gamma-nu channel due to two lepton loops is substantially e…
Quark spin coupling in baryons - revisited
J. Chizma, G. Karl
A direct connection can be made between mixing angles in negative parity baryons and the spin coupling of constituent quarks. The mixing angles do not depend on spectral data. Thes…
New Variational Principles in Classical and Semiclassical Mechanics
G. Karl, V. A. Novikov
We demonstrate that reciprocal Maupertuis' Principle is the classical limit of Schrödinger's Variational Principle in Quantum Mechanics.
Strange quarks, magnetic moments and SU(3)
J. Chizma, G. Karl
We discuss the agreement in sign between the recently measured strange contribution to the proton magnetic moment and SU(3) based fits to baryon octet magnetic moments.
Isospin Violation in Hyperon Semileptonic Decays
Gabriel Karl
This note emphasizes that due to isospin violation the two central states in the octet mix, and this mixing can be measured in semileptonic decays, in particular with an accurate d…
Gluonic states in two space dimensions
Gabriel Karl, Jack Paton
We discuss the ``spectroscopy'' of gluonic states in systems with two space dimensions, using simple models to mimic the results of lattice gauge theory computations. We first disc…
