Experimental Status of BB Physics

A short summary is given of the current status of B physics. Reasons for physics beyond the Standard Model are discussed. Constraints on New Physics are given using measurements of B mixing, Bs mixing, and CP violation, along with |Vub. Future goals, and upcoming new experiments are also mentioned.Comment: Invited talk at X Mexican Workshop on Particles and Fields, Morelia, Michoacan, Mexico, Nov. 7-12, 2005; 16 pages and 12 figures; (added references

Pathological Science

I discuss examples of what Dr. Irving Langmuir, a Nobel prize winner in Chemistry, called "the science of things that aren't so." Some of his examples are reviewed and others from High Energy Physics are added. It is hoped that discussing these incidents will help us develop an understanding of some potential pitfalls.Comment: Presented at Theoretical Advanced Study Institute In Elementary Particle Physics (Tasi), University of Colorado, Boulder, Colorado June, 2000.

Future of Heavy Flavour Physics: Experimental Perspective

I discuss what measurements need to be done to search for physics beyond the Standard CKM model, rather than just what studies can be done in the near future. It is also important to accurately measure the CKM matrix elements. Current best estimates for two important elements are: |V_{cb}|=0.0381 +/- 0.0021 and |V_{ub}/V_{cb}|=0.085 +/- 0.019. Finally, future experiments are discussed.Comment: Presented at "Heavy Flavours 8," Southampton, UK, July 1999, 9 pages 7 figure

Heavy Flavor Physics

The main purpose of Heavy Flavor experiments is to discover physics beyond the Standard Model, or characterize it, should it be found elsewhere. Thus, current limits on New Physics (NP) are reviewed. New results are presented, some involving processes that could show NP even with current data. Specific topics include the CKM element |Vub|, the forward-backward asymmetry in B -> K* mu+ mu-, b-hadron fractions at the LHC, B(Bs -> mu+ mu-), first observations of several Bs and Bc decay modes, the X(4140), new b-baryons and their decays, searches for Majorana neutrinos, and Lepton Flavor Violation.Comment: To appear in Proceedings of the DPF-2011 Conference, Providence, RI, August 8-13, 2011, 16 pages, 26 figures; version 2 fixed some typographical error

Future B Experiments from The BTeV/LHC-b Perspective

Many measurements are necessary in the program of studying mixing, CP violation and rare decays of b and c quarks. These measurements require large numbers of B^o, B_s, B^- and D^{*+} hadrons. Fortunately, copius production of particles containing b and c quarks will occur at Tevatron and the LHC. The crucial measurements are described here, as well as the design of the two experiments, LHC-b and BTeV, that can exploit the 4-20 x 10^{11} b hadrons produced every 10^7 seconds.Comment: Presented at the 3rd International Conference on B Physics and CP Violation, Taipei, December 3-7, 1999 15 pages, 10 figure

Time-dependent Dalitz-plot formalism for B_q -> J/\psi\ h+ h-

A formalism for measuring time-dependent CP violation in B_q -> J/\psi h+ h- decays with J/\psi-> mu+ mu- is developed for the general case where there can be many h+ h- final states of different angular momentum present. Here h refers to any spinless meson. The decay amplitude is derived using similar considerations as those in a Daltiz like analysis of three-body spinless mesons taking into account the fact that the J/\psi is spin-1, and the various interferences allowed between different final states. Implementation of this procedure can, in principle, lead to the use of a larger number of final states for CP violation studies.Comment: To be published in Physics Lett.

Method of Studying Λb0\Lambda_b^0 decays with one missing particle

A new technique is discussed that can be applied to $\Lambda_b^0$ baryon decays where decays with one missing particle can be discerned from background and their branching fractions determined, along with other properties of the decays. Applications include measurements of the CKM elements $|V_{ub}|$ and $|V_{cb}|$, selected charmless decays, and detection of any exotic objects coupling to $b\to s$ decays, such as the inflaton.Comment: 6 pages, 2 figures, updated for referees comments on July 16, 201
