On the neutron electric dipole moment in the Weinberg CP-violation model
Abstract The neutron EDM in the Weinberg CP-violation model is shown to be dominated by the neutral Higgs boson interaction and to exceed the present experimental limitations by 2–3 orders ofExpand

On the Distribution of Neutral and Charged Pions through the Production of a Classical Pion Field
High energy reactions may produce a state around the collision point that is best described by a classical pion field. Such a field might be an isospin rotated vacuum of the chiral $\sigma$-model or,Expand

A second massless axion
Abstract It is suggested that the Higgs and the Yukawa couplings of the standard model possess two global U(1)-symmetries: independent chiral rotations of quarks and leptons. The model requires theExpand

Astrophysical limits on the existence of light vector particles
The purpose of this work is to study astrophysical limits on the existence of light vector particles, interacting with a nonconserved current, for example with the hypercharge current. The interestExpand
Simple model for spin-crisis
Starting from the additive quarkSU(6) model and taking into account the pion and kaon (η) emission during the initial stage of evolution (fromq2∼mquark2 toq2∼1 GeV2) we convert the main fraction ofExpand

Production of classical pion field and/or disoriented chiral condensate
We discuss the possibility of production of a classical pion field in high energy nuclei-nuclei collisions. We show that the occupation number for the produced pions can be large as required for theExpand

CP violation in the Kobayashi-Maskawa model with four generations
A useful method of parametrizing the mixing matrix is proposed. It is shown that the value of epsilon and the ratio epsilon'/epsilon of either sign can easily account for the existence of the fourthExpand
Possible new long-range interaction and methods for detecting it
The possible existence of a stable, massless, 0/sup - +/ Goldstone particle exhibiting a semiweak interaction with fermions (an arion) is discussed. An arionic long-range interaction could beExpand
