Theoretical Issues in Flavor Physics

Quark and lepton flavor physics presents us with a basic question: Can we understand the pattern of masses and mixings of the known quarks and leptons, and how do present and proposed measurements help to advance that goal? Topics discussed include the apparent suppression of new flavor-changing effects, the status of quark and lepton mixing, the implications of new measurements of CP asymmetries in heavy quark decays, the impications of forthcoming experiments on the muon's anomalous magnetic moment and its transitions to an electron, and what we can hope to learn from electric dipole moments.Comment: 11 pages, 3 figures, presentation at the DPF 2013 Meeting of the American Physical Society Division of Particles and Fields, Santa Cruz, California, August 13-17, 2013.

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.

M2 signatures in psi(2S) radiative decays

The sensitivity of observables in radiative decays psi(2S) -> gamma chi_{1,2} -> gamma gamma J/psi to quadrupole (M2) admixtures in the dominant electric dipole (E1) transitions is explored. Emphasis is placed on distributions in a single angle, and several examples are given.Comment: 8 pages, 4 figures, to be submitted to Phys. Rev. D. Additional data and referenc

BB Physics (Theory)

Some theoretical aspects of $B$ physics are reviewed. These include a brief recapitulation of information on weak quark transitions as described by the Cabibbo-Kobayashi-Maskawa (CKM) matrix, a description of CP asymmetries in $B$ decays to CP eigenstates and self-tagging modes, a discussion of final-state phases in $B$ and charm decays, some topics on $B_s$ properties and decays, the prospects for unusual excited $B$ states opened by discovery of some narrow $c \bar s$ resonances, and the prospects for seeing the heavier $Q=1/3$ quarks predicted in some extended grand unified theories.Comment: 23 pages, LaTeX, 12 figures, invited talk presented at Fourth Tropical Workshop, Cairns, Australia, 9--13 June 2003.

Present and Future Aspects of CP Violation

This series of five lectures describes aspects of CP violation, emphasizing its description within the standard electroweak model. After discussing the kaon system, the only place in which CP violation has been seen so far, we turn to the leading contender for the effect, complex phases in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. A number of suggestions are made for improved tests of the standard picture. Hadrons containing $b$ quarks play a key role in this program, and are discussed separately. We also mention a number of non-standard and speculative aspects of CP violation, including alternatives to the CKM description, direct tests of time reversal invariance, and baryogenesis.Comment: 58 pages, latex, 14 uuencoded figures sent separatel

Learning the weak phase γ\gamma from B decays

The current status of some methods to determine the weak phase $\gamma$ of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $V^*_{ub}$ using B decays is discussed, and comments are made on accuracy achievable in the next few years.Comment: 7 pages, 9 figures, talk given at the 9th International Conference on B-Physics at Hadron Machines (BEAUTY 2003), CMU, Pittsburgh, October 2003.
