Jet production by a gluon source in QCD
(Elsevier, 1978-12-25)
The properties of jets produced by a gluon source are examined in QCD. We give a simple derivation of the jet opening angle (up to an undetermined constant) using arguments of general applicability. At asymptotic energies, ...
The influences of roughness on film thickness measurements by Mueller matrix ellipsometry
(The American Institute of Physics, 1994-09)
The accuracy of measurement of the thickness of uniform thin films on solid substrates by null ellipsometry is severely limited when the substrate is rough. It is impossible to separate these two effects experimentally ...
Cosmic string in the van Stockum cylinder
(IOP Publishing Ltd, 2003-05-07)
The low density van Stockum dust solution is extended by including an angular deficit factor. The resulting model describes a rotating Gott–Hiscock string surrounded by an annular dust atmosphere. The interior spacetime ...
Obtaining real parts of scattering amplitudes directly from cross section data using derivative analyticity relations
(Elsevier, 1974-04-15)
We show that one can obtain real parts of scattering amplitudes by knowing the imaginary parts at only nearby energies. This is accomplished by re-casting the dispersion integral into an equivalent form which we will calla ...
WHITE‐LIGHT RECONSTRUCTION OF COLOR IMAGES FROM BLACK‐AND‐WHITE VOLUME HOLOGRAMS RECORDED ON SHEET FILM
(The American Institute of Physics, 1966-09-01)
The method of ``white‐light reflection holography'' first described by Stroke and Labeyrie (Physics Letters 20, 368, March 1, 1966) and subsequently verified by a number of authors, has now been extended to the recording ...
Higgs boson coupling to b quarks: targets in the MSSM
(2017-09-07)
Estimates are made of the possible deviations of the Higgs coupling strength to bottom quarks due to contributions from additional particles and interactions of the Minimal Supersymmetric Standard Model.
Direct, high resolution, four‐dimensional measurements of the fine scale structure of Sc≫1 molecular mixing in turbulent flows
(The American Institute of Physics, 1991-05)
Results from highly resolved, four‐dimensional measurements of the fine structure of the fully space‐ and time‐varying Sc≫1 conserved scalar field and the associated scalar energy dissipation rate field in a turbulent flow ...
Controlling the motion of interacting particles: Homogeneous systems and binary mixtures
(The American Institute of Physics, 2005-06)
We elaborate on recent results on the transport of interacting particles for both single-species and binary mixtures subject to an external driving on a ratchetlike asymmetric substrate. Moreover, we also briefly review ...
