B-L Neutrinos
Kevin Cahill
Neutrino masses and mixings are analyzed in terms of left-handed fields and a 6x6 complex symmetric mass matrix whose singular values are the neutrino masses. An angle theta_nu cha…
Neutrinos Are Nearly Dirac Fermions
Kevin Cahill
Neutrino masses and mixings are analyzed in terms of left-handed fields and a 6x6 complex symmetric mass matrix whose singular values are the neutrino masses. An angle x_nu charact…
Elements of Supersymmetry
Kevin Cahill
These notes are intended to provide an introduction to supersymmetry. The notes begin with supersymmetric quantum mechanics and the basic properties of spinor fields. The supersymm…
Condensates Break Chiral Symmetry
Kevin Cahill
In the physical vacuum of QCD, the energy density of light-quark fields strongly coupled to slowly varying gluon fields can be negative. The states that drive this energy density l…
Chiral Symmetry and Quark Confinement
Kevin Cahill
In the physical vacuum of QCD, the energy density of light-quark fields strongly coupled to slowly varying gluon fields can be negative, and so a condensate of pairs of quarks and…
Confinement Artifacts in the U(1) and SU(2) Compact Lattice Gauge Theories
Kevin Cahill, Gary Herling
We identify the artifact that causes confinement at strong coupling in compact U(1) lattice gauge theory and show that most of the string tension in compact SU(2) lattice gauge the…
