Morris Dees (with Steve Fiffer). A lawyer\u27s journey : the Morris Dees story. Chicago: American Bar Association, 2001

Literally and figuratively, Dees has led the dangerous, examined life. As our students often consider, there is a real-life, a risky connection between who one is, what one knows, and how one acts. Dees exemplifies this connection

Indirect Measurement of the Vertex and Angles of the Unitarity Triangle

The precise measurements of the Bd oscillation frequency and the limit on the Bs one one as well as the determination of the Cabibbo-Kobayashi-Maskawa matrix element Vub improve the constraints on the other elements of this matrix. A fit to the experimental data and the theory calculations leads to the determination of the vertex of the unitarity triangle as: rho = 0.160 -0.070 +0.094 eta = 0.381 -0.058 +0.061. The values of its angles, in their customary definition in terms of sines for alpha and beta, are found to be: sin(2 alpha) = 0.06 -0.42 +0.35 sin(2 beta) = 0.75 +/- 0.09 gamma = 68 -12+11o. Indirect information on non-perturbative QCD parameters, on the presence of a CP violating complex phase in the CKM matrix and on the Bs oscillation frequency are also extracted.Comment: 12 pages, submitted to Physics Letters

ZZ Cross Section Measurements

Results on the cross section measurement of Z boson pair-production at LEP are presented. The more general case of neutral-current four-fermion production and the particular case of ZZ events enriched in b quarks are also discussed. All the results agree with the Standard Model predictions.Comment: To appear in the proceedings of ICHEP 2000, Osaka, Japan, July 27th-August 2nd, 200

Recent Results from the L3 Experiment

A data sample corresponding to an integrated luminosity of 232pb^-1 was collected in 1997 and 1998 by the L3 experiment at LEP in e+e- collisions at centre-of-mass energies between 181.7GeV and 188.7GeV. Pair production of fermions and bosons is studied and compared with the Standard Model expectations. Events with a single detected photon or W boson are also considered. The measurement of several Standard Model cross sections is discussed. The presence and the magnitude of triple couplings of charged and neutral electroweak gauge bosons is investigated. These processes are used to probe New Physics beyond the Standard Model, including the existence of extra spatial dimensions.Comment: 17 Pages, 11 Figures, to appear in the proceedings of the XIV International Workshop on Quantum Field Theories and High Energy Physics, QFTHEP99, Moscow, Russia, 27 May - 2 June, 199

Measurements of the Running of the Electromagnetic Coupling at LEP

The study of Bhabha scattering at e^+e^- colliders probes the running of the electromagnetic coupling. After early measurements by the VENUS collaboration at TRISTAN and the by L3 collaboration at LEP, two recent analyses have been performed by the OPAL and L3 collaborations. The OPAL collaboration studied high-statistics low-angle Bhabha scattering at LEP, achieving a precise determination of the running of alpha in the region 1.8GeV^2<-Q^2<6.1GeV^2. The L3 collaboration investigated high-energy large-angle Bhabha scattering to first probe the region 1800GeV^2 < -Q^2 < 21600GeV^2. All measurements are described and a global overview of their agreement with QED predictions is given.Comment: Invited talk at the XXVI Physics in Collisions Conference (PIC06), Buzios, Brasil, July 2006, 6 pages, LaTeX, 7 eps figures.

Indirect Determination of the Vertex and Angles of the Unitarity Triangle

The values of the elements of the Cabibbo-Kobayashi-Maskawa matrix are constrained by direct and indirect measurements. A fit to experimental data and theory calculations allows the indirect determination of the vertex and angles of the unitarity triangle as: rho = 0.18 +/- 0.07 eta = 0.35 +/- 0.05 sin 2alpha = 0.14 +0.25 -0.38 sin 2beta = 0.73 +/- 0.07 gamma = 63 +8 -11 degrees. Information is derived on the presence of CP violation in the matrix, on non-perturbative QCD parameters and on the Bs oscillation frequency.Comment: Presented at the 5th International Symposium on Radiative Corrections (RADCOR-2000) Carmel CA, USA, 11-15 September, 200
