On the Speed of Gravity and the v/cv/c Corrections to the Shapiro Time Delay

Using a relatively simple method, I compute the v/c correction to the gravitational time delay for light passing by a massive object moving with speed v. It turns out that the v/c effects are too small to have been measured in the recent experiment involving Jupiter and quasar J0842+1845 that was used to measure the speed of gravity.Comment: 8 pages, LaTeX (or Latex, etc), one figure, which is also available at http://www-theory.lbl.gov/~samuel/sog_figure.pdf; Revised version is the one to appear in Phys.

The Standard Model in Its Other Phase

The standard model of particle physics is analyzed for the case of a Higgs potential not favoring spontaneous electroweak symmetry breaking to gain insight into the physics of the standard model. Electroweak breaking still takes place, and quarks and leptons still acquire masses but through bosonic technicolor. This ``other'' phase of the standard model exhibits interesting phenomena.Comment: Latex, 22 pages, 2 figure

Selling the Fourth Revolution: The Correlation between C-Suite Architecture and a Big Data Mindset as Portrayed in the Letter to the Shareholders

Big data’s diverse applications for the modern data deluge span problems and industries. While offering titular possibilities, is big data an area of serious corporate inquiry or is it a source of hype? This research seeks to add to the growing body of management literature on big data. C-suite architecture additions of a CIO and/or a CTO demonstrate an environment for and increased BDA mindset. A review of the annual letter to the shareholder is a proxy for the external narrative of a big data strategy. To measure correlation between C-suite structure and outward narrative, a regression for eight industries, from 2011 to 2014, measure correlation between external and organizational positioning. Additional regressions examine industry-sensitivity and leader-laggard dynamics. Five of the eight industries demonstrate correlation between architectural repositioning and perceived investor support for big data, indicating that big data intensive C-suite architecture correlates with letter to the shareholder big data emphasis

The Earliest Phase Transition?

The question of a phase transition in exiting the Planck epoch of the early universe is addressed. An order parameter is proposed to help decide the issue, and estimates are made concerning its behavior. Our analysis is suggestive that a phase transition occurred.Comment: Latex, 10 pages, 1 figure, to appear in Nucl. Phys.

Electromagnetic and Weak Moments of the Tau-Lepton

The electromagnetic and weak dipole moments of the Tau-lepton have been measured by experiments at e+e- colliders. Data samples of e+e- --> tau+tau-, e+e- --> tau+tau- gamma and e+e- --> e+e-tau+tau- events collected at centre-of-mass energies between 10 and 200 GeV are used. No deviation from the Standard Model is found. Limits on the moments are summarised from the most recent results.Comment: 6 pages (Latex), 5 figures (postscript

The Lense--Thirring Effect and Mach's Principle

We respond to a recent paper by Rindler on the ``Anti--Machian'' nature of the Lense--Thirring effect. We remark that his conclusion depends crucially on the particular formulation of Mach's principle used.Comment: 13 pages, Latex file, no figure

The Goldstino Field in Linear and Nonlinear Realizations of Supersymmetry

A Goldstino field in the nonlinear realization of supersymmetry is constructed from an appropriate chiral super-multiplet of the linear theory, in general O'Raifeataigh-like models. The linear theories can thus be reformulated into their nonlinear versions, via the standard procedure. The Goldstino field disappears totally from the original Lagrangian in the process, but reemerges in the Jacobian of the transformation and covariant derivatives. Vertices with Goldstino fields carry at least one space-time derivative, as one would have expected.Comment: 7+1 pages, Late

Natural Entropy Production in an Inflationary Model for a Polarized Vacuum

Though entropy production is forbidden in standard FRW Cosmology, Berman and Som presented a simple inflationary model where entropy production by bulk viscosity, during standard inflation without ad hoc pressure terms can be accommodated with Robertson-Walker's metric, so the requirement that the early Universe be anisotropic is not essential in order to have entropy growth during inflationary phase, as we show. Entropy also grows due to shear viscosity, for the anisotropic case. The intrinsically inflationary metric that we propose can be thought of as defining a polarized vacuum, and leads directly to the desired effects without the need of introducing extra pressure terms.Comment: 7 pages including front one.
