Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Detailed properties of the neutrino streaming instability in a plasma are investigated for two particular choices of beamed neutrino distributions that permit exact analytical solutions to the dispersion relation. The dispersion relation is solved analytically, and it is shown that the maximum instability growth rate scales with powers κ of the Fermi constant GF lower than 2 (1 ≤ κ ≤ 4/3). For conditions present in type II supernovae, the neutrinos are sufficiently collimated for the neutrino streaming instability to operate.
