Neutral Current Reactions and SU(3)xU(1) Gauge Models

A Neutral Current Constraint and Gauge Model

43 The experimental observation R’/RV < c$/$ , i. e. , ok > c& where cc N , are the v-(5-) induced charged and neutral current inclusive cross sections on an isospin 0 nucleon and R provides a constraint on the possible quark representations among various SU(2) x U(1) gauge models. We have examined the energy dependence of both V-(i?-) induced charged and neutral current processes in the models...

Neutral-current neutrino reactions in the supernova environment

We study the neutral-current neutrino scattering for four nuclei in the iron region. We evaluate the cross sections for the relevant temperatures during the supernova core collapse and derive Gamow-Teller distributions from large-scale shell-model calculations. We show that the thermal population of the excited states significantly enhances the cross sections at low neutrino energies. Calculati...

The Spatial Limitations of Current Neutral Models of Biodiversity

The unified neutral theory of biodiversity and biogeography is increasingly accepted as an informative null model of community composition and dynamics. It has successfully produced macro-ecological patterns such as species-area relationships and species abundance distributions. However, the models employed make many unrealistic auxiliary assumptions. For example, the popular spatially implicit...
