The measurement of sin(2beta)

Since the first observation in 1964, CP violation remains one of the most elusive aspects of the standard model. The CDF collaboration has reported the first evidence of CP violation in the B system using the world's largest sample of $B \to J/\psi K^0_S$ decays. The direct measurement of sin$(2\beta)$=0.79$^{+0.41}_{-0.44}$ (combined statistical and systematic error) agrees with the standard model predictions. New data collected from the B-factories and from the upgraded experiments at the Tevatron should allow a more precise measurement of $\sin 2\beta$ in the near future.Comment: Presented at Heavy Flavours 8, Southampton, UK, 1999.

The Importance of Silicon Detectors for the Higgs Boson Discovery and the Study of its Properties

Recent studies are presented demonstrating the important role played by silicon detectors in the the discovery of the Higgs boson. CMS is planning to replace its in an extended technical stop of the LHC in the winter of 2016 . We present results showing that this replacement will significant increase the sample of Higgs bosons that will be reconstructed enabling precision studies of this particle.Comment: on behalf of the CMS Collaboratio

The Interplay Between Collider Searches For Supersymmetric Higgs Bosons and Direct Dark Matter Experiments

In this article, we explore the interplay between searches for supersymmetric particles and Higgs bosons at hadron colliders (the Tevatron and the LHC) and direct dark matter searches (such as CDMS, ZEPLIN, XENON, EDELWEISS, CRESST, WARP and others). We focus on collider searches for heavy MSSM Higgs bosons ($A$, $H$, $H^{\pm}$) and how the prospects for these searches are impacted by direct dark matter limits and vice versa. We find that the prospects of these two experimental programs are highly interrelated. A positive detection of $A$, $H$ or $H^{\pm}$ at the Tevatron would dramatically enhance the prospects for a near future direct discovery of neutralino dark matter. Similarly, a positive direct detection of neutralino dark matter would enhance the prospects of discovering heavy MSSM Higgs bosons at the Tevatron or the LHC. Combining the information obtained from both types of experimental searches will enable us to learn more about the nature of supersymmetry.Comment: 22 pages, 28 figure
