**Research Abstract**

I am currently blogging on Southern California, US, and World Energy and Environment. Since the current administration is destroying clean energy efforts, the blog has also turned to energy and environmental politics. It also defends our Constitutional Rights.

During the California energy crisis, I made up a set of web pages summarizing California Energy Data. I am continuing this interest in Energy by giving lectures to the Osher Lifelong Learning Institute on Our Energy Future.

I am also working with the UCI Osher Lifelong Learning Institute to provide outreach lectures in physics, by myself and by the Physics and Astronomy faculty.

My previous work in Elementary Particle Theory is described below (before 2002).

In elementary particle theory, we do research in electroweak theories which unify electromagnetic and weak interactions, exploring consequences of the currently verified standard model, and of models of particles beyond this, as could appear in new experiments, especially in B factories, at the tevatron at Fermilab, and at the LHC.

The physics of violation of fundamental particle and space-time symmetries has been intriguing, and that of time reversal violation in particle interactions (or CP violation, involving changing particles with antiparticles, and parity inversion) will soon be explored more cleanly in systems with the heavy bottom or b quark in B mesons at a B factory electron-positron collider and at hadron colliders. In these systems, constraints from fitting CP violating experiments in the K meson system, other CP experiments, and initial B factory experiments, have been used to predict the expected signal from the standard models in the CP violating decays of the B mesons. In models of physics beyond the standard model which contain more elementary quarks, new currents which mix quarks of the same charge occur, leading to new processes with more CP violating phases in the oscillations of B mesons into anti-B mesons. Despite bounds on these new currents, we show that effects of new physics models can be detected at a B factory. We have projected ahead to assuming results from the B factories, and found that additional experiments will be needed in combination with B factory results to verify or rule out models of physics beyond the standard model. My 2001 seminar at UC Irvine (in postscript or in pdf format) is on the model containing new down quarks. We have also analyzed the effect of the Left-Right Model which contains right-handed weak bosons, although at higher mass than the known left-handed weak bosons. I am continuing to update these models after

retirement.

Before retiring from teaching, I have taught Physics 136 (Particle Physics), Physics 237B (Elementary Particle Theory), and Physics 212A (Mathematical Physics). These courses have led to web material on Mathematica instruction, on making up equations in Microsoft Word, and in the solution of the Black-Scholes equation for valuing derivative investments, all on my webpage.
