Searching for new physics with CP violating B decays
The author explores the possibility of using CP violation in B decays to detect the presence of physics beyond the Standard Model. He first studies the possibility of new physics in the B-{anti B} mixing amplitude. He discusses a construction to extract information about the phase and magnitude of the new physics contribution, as well as the CKM parameters in a model independent way. He points out the difficulty of carrying through this program induced by hadronic uncertainties and discrete ambiguities, and suggests additional measurements to overcome these problems. He then studies the possibility of new physics contributions to the B meson decay amplitudes. The author emphasizes the sensitivity of the B {yields} {phi}K{sub S} decay to these new contributions, and explains how this sensitivity can be quantified using experimental data on SU(3) related decays. Finally, he analyzes a number of models where the B decay amplitudes are modified.
