The generation and decay of vorticity

Geophysical & Astrophysical Fluid Dynamics, 1984
Abstract Vorticity, although not the primary variable of fluid dynamics, is an important derived variable playing both mathematical and physical roles in the solution and understanding of problems. The following treatment discusses the generation of vorticity at rigid boundaries and its subsequent decay.

Rare Decays and the Fourth Generation

Annals of the New York Academy of Sciences, 1989
Rare decays are quite sensitive1 to physics beyond the Standard Model (SM), due to the effects of virtual, new, heavy particles (i.e., a fourth generation, SUSY, charged Higgs, E6 exotic fermions,…). These new contributions can either enhance or suppress (sometimes quite substantially) the rates for rare processes compared to the corresponding SM ...

Decay of Conservation Laws and Their Generating Functions

Acta Applicandae Mathematicae, 1995
The paper deals with decay velocity of the quantities which are conserved in absense of dissipation. The decay velocity (or the ``balance law'') may be found explicitly using the generating function of the conservation law. The general approach is illustrated by a certain system of MHD equations for incompressible magnetofluids.

On the decay of generalized Swihart waves

Physics of the Solid State, 1999
For Josephson junctions in sandwich geometry and in thin-film geometry we formulate the equations of nonlocal electrodynamics which take account of the influence of normal electrons in superconductors. On the basis of these equations we examine the spectrum and decay of generalized Swihart waves.

Fourth generation and nucleon decay in supersymmetric theories

Physical Review D, 1987
Analysis of nucleon decay in N=1 supergravity unified models including the effect of a fourth generation of matter is given. Experimental constraints from nucleon-lifetime limits on the Kobayashi-Maskawa (KM) matrix that enters nucleon decay are obtained.

Charmless decays of bottom mesons and a fourth generation

Physical Review Letters, 1987
B decays to charmless inclusive final states are discussed. The generic process is the loop-induced b..-->..sg/sup */, g/sup */ being an on-shell or off-shell gluon. We include the cases when the gluon momentum is lightlike, timelike, and spacelike. The timelike case includes g/sup */..-->..qq-bar and gg splitup. Our findings are as follows: (1) B(b..--

Flavor-changing decays of fourth-generation quarkonium

Physical Review D, 1989
We evaluate the flavor-changing neutral-current decays {ital S}({ital v{bar v}}){r arrow}{ital c{bar t}},{ital t{bar c}},{ital a{bar t}},{ital t{bar a}} of the {ital S}-wave quarkonium states formed from the {ital Q}={minus}1/3 charge {ital v} quark of a fourth-generation quark doublet ({ital a},{ital v}).
