A Note on the QCD Corrections to Forward--Backward Asymmetries of Heavy--Quark Jets in Z Decays

A. Djouadi, B. Lampe, P. M. Zerwas

The measurement of the forward-backward asymmetries of heavy quarks provides one of the most precise determinations of in decays. We discuss in detail the one--loop…

Higgs and Z boson decays into light gluinos

A. Djouadi, M. Drees

We calculate the decay rate of scalar and pseudoscalar Higgs bosons into a pair of gluinos, within the Minimal Supersymmetric Standard Model. In the theoretically and experimentall…

Extracting the Intermediate-Mass Higgs Resonance at Photon-Photon Colliders

M. Baillargeon, G. Belanger, F. Boudjema

We address the problem of how to extract the signal of a Higgs within the intermediate mass range at a photon-photon collider that has a wide energy spectrum. All backgrounds from…

Implications of the Top Quark Mass Measurement for the CKM Parameters, and CP Asymmetries

A. Ali, D. London

Motivated by the recent determination of the top quark mass by the CDF collaboration, $\mt =174 \pm 10 ^{+13}_{-12}$ GeV, we review and update the constraints on the parameters of…

Leading electroweak correction to Higgs boson production at proton colliders

A. Djouadi, P. Gambino

At proton colliders, Higgs particles are dominantly produced in the gluon--gluon fusion mechanism. The Higgs--gluons coupling is mediated by heavy quark loops, and the process can…

QCD corrections to Higgs boson self--energies and fermionic decay widths

A. Djouadi, P. Gambino

We present the QCD corrections to Higgs boson self-energies for arbitrary momentum transfer and for different internal quark masses, to treat the case of CP--even, CP--odd and char…

Higgs particles at future hadron and electron-positron colliders

A. Djouadi

The prospects for discovering Higgs particles and studying their fundamental properties at future high-energy electron-positron and hadron colliders are reviewed. Both the Standard…

CP Violation in the B System: What's Old, What's New?

David London

I review the many ways of obtaining information about the CKM matrix through CP violation in the system. I include direct and indirect CP violation, the role of penguins and is…

Low Energy Nucleon-Nucleon Scattering with the Skyrme Model in the Geodetic Approximation

T. Gisiger, M. B. Paranjape

We calculate nucleon-nucleon scattering at low energies and large impact parameter in the Skyrme model within the framework for soliton scattering proposed by Manton. This correspo…

Weak Coupling Phase from Decays of Charged B Mesons to and

Michael Gronau, Jonathan L. Rosner, David London

The theory of violation based on phases in weak couplings in the Cabibbo-Kobayashi-Maskawa (CKM) matrix requires the phase (in a standard convent…

Measuring Strong and Weak Phases in Time-Independent B Decays

Oscar F. Hernandez, David London, Michael Gronau +1

Flavor SU(3) symmetry implies certain relations among -decay amplitudes to , and final states, when annihilation-like diagrams are neglected. Using three t…

From Multiloop Spinor Helicity Technique to String Reorganization

C. S. Lam

The success of the spinor helicity technique for tree processes is reviewed. To apply it to multiloop diagrams one is naturally led to the Schwinger proper-time representation, who…

Determining the Quark Mixing Matrix From CP-Violating Asymmetries

R. Aleksan, B. Kayser, D. London

If the Standard Model explanation of CP violation is correct, then measurements of CP-violating asymmetries in meson decays can in principle determine the entire quark mixing m…

Single Dilepton Production at , and Colliders

N. Leporé, B. Thorndyke, H. Nadeau +1

We calculate the cross sections for the single production of doubly-charged dileptons, both scalar and vector, at , and colliders at GeV and 1 TeV.…
