This graduate text in quantum mechanics is based on the lectures of J. David Jackson at the University of California, Berkeley, in 1978-9 and 1987-88.

Grace in All Simplicity: Beauty, Truth, and Wonders on the Path to the Higgs Boson and New Laws of Nature, by Robert N. Cahn and Chris Quigg

This undergraduate/graduate text in particle physics, by Robert Cahn and Gerson Goldhaber, presents the subject from a historical perspective.

Designed to acquaint students of particle physics already familiar with SU(2) and SU(3) with techniques applicable to all simple Lie algebras, this text is especially suited to the study of grand unification theories.

Search for Cosmic Parity Violation

The four-point correlation of galaxies can reveal parity violation generated at the beginning of the Universe. Our first analysis of data from BOSS is intruiging: arXiv 2206:03625

This was the culmination of work that began with an investigation of isotropic n-point functions and their algebra arXiv 2010.14418.pdf.

We realized that some isotropic four-point functions were parity-odd and proposed a search in large-scale structure for parity violation arXiv 2110.12004

Eighteen Arbitrary Parameters of the Standard Model in Your Everyday Life

I have written a semi-technical paper (appropriate for beginning graduate students in physics), which has been published in Reviews of Modern Physics, 68, 951 (1996).

Einstein, Your Cell Phone, and You

In 2000 I wrote a piece about the purported dangers of cell phones, which was published in the San Francisco Chronicle.

X-ray Imaging

I have worked with Dave Nygren and his team on the development of an x-ray imaging system, based on silicon strip technology. This work grew out of detector development for the Superconducting Super Collider: it is a real spin-off. I have written a few short notes on related topics.
• Optimal Energy Weighting for a Monochromatic X-ray Beam
See also the published work.
• Simple Analytic Model for Refractive X-ray Focusing
• Determination of Statistical Power of Longitudinally Segmented Silicon-strip Detectors for X-ray Imaging

See, as well, our work on refractive x-ray lenses.

LHC Physics

• Vector Boson Fusion was developed by Sally Dawson and myself. Phys. Lett. 135, 196 (1984).
• Using jets to tag VBF was proposed by S. Ellis, R. Kleiss, J. Stirling, and myself:Phys. Rev. D 35, 1626 (1987).

Azimuthal Dependence in Leptoproduction

The azimuthal distribution of the hadronic jet produced in leptoproduction reflects the underlying transverse momentum distribution of the quarks in the target hadron. Phys.Lett. 78B (1978) 269
