P RESENT day interest in the high-speed performance of hydrofoil boats, ship propellers, pumps, and turbines has resulted in an intensive study of cavitation in liquid flows. During this process the flow field changes significantly from that of a homogenous single-phase flow. Forces, pressure distributions, and other performance characteristics are then correspondingly altered and these changes...

ALEPH Four - Jet Excess , R b and R − Parity Violation ∗

We review briefly the indications for some relatively light superpartners based on the Rb anomaly and discuss the dependence of the potential increase in Rb on the assumption about R−parity (non)conservation. We point out that the exotic 4-jet events reported by ALEPH may constitute a signal for supersymmetry with such a light spectrum and with explicitly broken R−parity. A parton level simulat...

Probability Distributions and Coherent States of B r , C r and D r Algebras

A new approach to probability theory based on quantum mechanical and Lie algebraic ideas is proposed and developed. The underlying fact is the observation that the coherent states of the Heisenberg-Weyl, su(2), su(r+1), su(1, 1) and su(r, 1) algebras in certain symmetric (bosonic) representations give the “probability amplitudes” (or the “square roots”) of the well-known Poisson, binomial, mult...

Testing Extended Technicolor with R B * )

Two outstanding questions in particle theory are the cause of electroweak symmetry breaking and the origin of the masses and mixings of the fermions. Because theories that use light, weakly-coupled scalar bosons to answer these questions suffer from the hierarchy and triviality problems, it is interesting to consider the possibility that electroweak symmetry breaking arises from strong dynamics...
