Precision tests of electroweak theory

  • 1. Brookhaven National Lab., Upton, NY (United States)

Description

Pursuits of 'New Physics' via precision measurements are surveyed. The inconsistency between world average tau lifetime-mass values and measured leptonic branching ratios is updated and a heavy neutrino solution is described. The use of Rτ ≡ Γ(τ → ντ + hadrons)/Γ(τ → e bar νeντ) to determine ΛMS is discussed. Constraints on the Peskin-Takeuchi S and T parameters are given. Possible evidence for low energy supersymmetry from grand unified theories is scrutinized. 20 refs., 2 tabs
