Congressional Discretion in Dealing with the Federal Rules of Evidence

On November 20, 1972, the Supreme Court, pursuant to statutory authority, adopted the Federal Rules of Evidence. The new rules of evidence were not to take effect, however, until ninety days after they had been submitted to Congress. The rules were officially submitted on February 5, 1973, but even before that date they had become the subject of extensive legislative debate. While some attorneys praise the codification of evidence rules as a progressive step, others maintain that certain of these promulgations will have an objectionable impact on the federal judicial system or that the Supreme Court has exceeded its authority to adopt rules of practice and procedure. As a result of this controversy, Congress has enacted a measure which defers the effective date of the rules until approved by an Act of Congress. The objections raised reemphasize a problem that has existed ever since Congress granted to the Supreme Court the power to enact rules of practice and procedure : it is unclear what power Congress possesses to modify rules it considers offensive or beyond the authority of the Supreme Court to adopt. This article focuses on the terms of the applicable rules enabling statutes and examines the various methods by which Congress may respond to the rules

Measurement of the Ratio of b Quark Production Cross Sections in Antiproton-Proton Collisions at 630 GeV and 1800 GeV

We report a measurement of the ratio of the bottom quark production cross section in antiproton-proton collisions at 630 GeV to 1800 GeV using bottom quarks with transverse momenta greater than 10.75 GeV identified through their semileptonic decays and long lifetimes. The measured ratio sigma(630)/sigma(1800) = 0.171 +/- .024 +/- .012 is in good agreement with next-to-leading order (NLO) quantum chromodynamics (QCD)

B-meson decays to eta ' rho, eta ' f(0), and eta ' K*

We present measurements of B-meson decays to the final states eta'rho, eta'f(0), and eta'K*, where K* stands for a vector, scalar, or tensor strange meson. We observe a significant signal or evidence for eta'rho(+) and all the eta'K* channels. We also measure, where applicable, the charge asymmetries, finding results consistent with no direct CP violation in all cases. The measurements are performed on a data sample consisting of 467 X 10(6) B (B) over bar pairs, collected with the BABAR detector at the PEP-II e(+)e(-) collider at the SLAC National Accelerator Laboratory. Our results favor the theoretical predictions from perturbative QCD and QCD factorization and we observe an enhancement of the tensor K-2*(1430) with respect to the vector K*(892) component

Improved measurement of B+->rho(+)rho(0) and determination of the quark-mixing phase angle alpha

We present improved measurements of the branching fraction B, the longitudinal polarization fraction f(L), and the direct CP asymmetry A(CP) in the B meson decay channel B+->rho(+)rho(0). The data sample was collected with the BABAR detector at SLAC. The results are B(B+->rho(+)rho(0))=(23.7 +/- 1.4 +/- 1.4)x10(-6), f(L)=0.950 +/- 0.015 +/- 0.006, and A(CP)=-0.054 +/- 0.055 +/- 0.010, where the uncertainties are statistical and systematic, respectively. Based on these results, we perform an isospin analysis and determine the Cabibbo-Kobayashi-Maskawa phase angle alpha=arg(-VtdVtb*/VudVub*) to be (92.4(-6.5)(+6.0))degrees
