CP Violation: Past, Present, and Future

We discuss the history of CP violation and its manifestations in kaon physics, its explanation in terms of phases of the Cabibbo-Kobayashi-Maskawa matrix describing charge-changing weak quark transitions, predictions for experiments involving $B$ mesons, and the light it can shed on physics beyond the Standard Model.Comment: 13 pages, LaTeX, 8 figures, Invited talk presented at XXI Brazilian National Meeting on Particles and Fields, Sao Lourenco, Minas Gerais, October 23--26, 2000, proceedings to be published in a special issue of the Brazilian Journal of Physics.

Ecological Biopower, Environmental Violence Against Animals, and the "Greening" of the Factory Farm

The promulgation of pollution control regulations governing factory farms has led to a striking new way of representing and intervening in the bodies of farmed animals: the body is being represented as a source of pollution, and various technological interventions, from genetic engineering to dietary changes, are being deployed to reduce pollution at the source. In this article I analyze this new technoscientific project through the theoretical lens of ecological biopower. Focusing on the industrial pork sector's efforts to keep the cost of complying with nutrient management regulations in check, the article examines the case of “environmental nutrition,” a dietary strategy that aims to reduce the excretion of nutrients from the bodies of swine. By highlighting whose diet is being changed in this approach and whose is not, I argue that environmental nutrition is as much about avoiding the exercise of ecological biopower over human beings as it is about exercising ecological biopower over farmed animals. I also argue that the pressing need to reduce the environmental impacts of factory farming is being used to justify new forms of violence against animals

Dark Matter and Indirect Detection in Cosmic Rays

In the early years, cosmic rays contributed essentially to particle physics through the discovery of new particles. Will history repeat itself? As with the discovery of the charged pion, the recent discovery of a Higgs-like boson may portend a rich new set of particles within reach of current and near future experiments. These may be discovered and studied by cosmic rays through the indirect detection of dark matter.Comment: 8 pages, to appear in the Proceedings of Centenary Symposium 2012: Discovery of Cosmic Rays, Denver, Colorado, June 201

Introduction to BB Physics

A short introduction to some current topics in $B$ physics is presented in order to set the stage for some results to be announced at this Workshop. After briefly reviewing the Cabibbo-Kobayashi-Maskawa (CKM) matrix and information on its parameters, the decays of neutral $B$ mesons to several CP eigenstates, and some $B \to \pi K$ decays, are discussed. It is shown that progress is being made on determination of all the angles of the unitarity triangle.Comment: 12 pages, LaTeX, 7 figures plus photo, invited talk presented at XXXVIII Rencontres de Moriond: Electroweak Interactions and Unified Theories, Les Arcs, France, March 15-22, 2003.

Exotic states of matter in heavy meson decays

The potential of decays of mesons containing heavy quarks [including $B$ mesons and the $\Upsilon(1S)$] for producing final states of matter with unusual quark configurations, such as $q q \bar q \bar q$ or $q q q q \bar q$, is investigated. The usefulness of antineutron detection in such searches is stressed.Comment: 15 pages, 8 figures, submitted to Phys. Rev. D. References and some text adde
