The Determination of the CKM Matrix

A general discussion of the Cabibbo-Kobayashi-Maskawa (CKM) matrix is given and the importance stressed of determining the matrix elements as an essential part of understanding CP violation in and beyond the Standard Model. The status of knowledge of the matrix elements connecting the first and second generation quarks is reviewed. A perspective on determinations of the full CKM matrix is presented as an introduction to the separate contributions to the panel discussion that follows.Comment: Invited talk at Beauty 2000, Kibbutz Maagan, Israel, September 13-18, 2000; 6 pages; no figure

Canonical Symplectic Representations for Prime Order Conjugacy Classes of the Mapping-class Group

In this paper we find a unique normal form for the symplectic matrix representation of the conjugacy class of a prime order element of the mapping-class group. We find a set of generators for the fundamental group of a surface with a conformal automorphism of prime order which reflects the action the automorphism in an optimal way. This is called an {\sl adapted} homotopy basis and there is a corresponding {\sl adapted presentation}. We also give a necessary and sufficient condition for a prime order symplectic matrix to be the image of a prime order element in the mapping-class group.Comment: 24 pages; change in title; typos corrected; some theorems revised; computational complexity added; final version of paper to appear in Journal of Algebr

The Attorney-Client Privilege Protection Act: The Prospect of Congressional Intervention into the Department of Justice\u27s Corporate Charging Policy

This Note analyzes the Privilege Protection Act, focusing on how it might change corporate white-collar prosecutions. Part I of this Note explores the mechanics of the corporate privilege, the development of the DOJ\u27s waiver policy, and the structure of the Privilege Protection Act. Part II addresses the conflicting views on whether the Privilege Protection Act will bolster corporate attorney-client privilege, provide for the effective and efficient prosecution of white-collar crime, and promote ethical prosecutorial practices. Finally, Part III argues that the Privilege Protection Act is a misguided attempt to correct a greater systemic problem with the corporate attorney-client privilege and the nature of corporate cooperation. If Congress is to act, it should recognize the essential role privilege waiver plays in prosecuting white-collar crime, and should move to limit the deleterious ramifications to corporations of routine privilege waivers. Thus, the doctrine of selective waiver would be a preferable remedy: it would protect the confidentiality of privileged documents that the corporation discloses to the government, and would provide an effective means to balance the corporation\u27s interest in cooperating with the government and avoiding unwarranted civil liability
