In Pursuit of Gamma

R. Aleksan, B. Kayser, D. London

After reviewing techniques for extracting clean information on CP-violating phase angles from decays, we explain the rules for finding decay modes that can probe the phase angl…

Model-Independent Global Constraints on New Physics

C. P. Burgess, S. Godfrey, H. König +2

Using effective-lagrangian techniques we perform a systematic survey of the lowest-dimension effective interactions through which heavy physics might manifest itself in present exp…

Electroweak gauge bosons self--energies: complete QCD corrections

A. Djouadi, P. Gambino

We present the (two--loop) QCD corrections to the longitudinal and transverse components of the electroweak gauge bosons self--energies for arbitrary momentum transfer and for diff…

Single Leptoquark Production

G. Belanger, D. London, H. Nadeau

The single production of leptoquarks in , and linear colliders is discussed. We show that these new particles could be seen in such machines even if their mass is…

{\Large{\bf Higgs or Neutral Vector Boson Production with a Pair in {\LARGE } Collisions}}

M. Baillargeon, F. Boudjema

Exploiting the fact that pair production in high-energy collisions is very large, we use this process to trigger Higgs, or photon radiation. We find that there are siz…

New Fermions at ee Colliders: II.~Signals and Backgrounds

G. Azuelos, A. Djouadi

We discuss the production, at high--energy ee linear colliders, of new heavy fermions predicted by extensions of the Standard Model. We analyze in great details the various…

New Fermions at ee Colliders: I. Production and Decay

A. Djouadi

We analyze the production in collisions of new heavy fermions stemming from extensions of the Standard Model. We write down the most general expression for the production…

On the asymptotic behavior of the electroweak gauge bosons vacuum polarization functions for arbitrary quark masses

A. Djouadi, P. Gambino

We derive the QCD corrections to the electroweak gauge bosons vacuum polarization functions at high and zero--momentum transfer in the case of arbitrary internal quark masses. We t…

Single Leptoquark Production at and Colliders

G. Belanger, D. London, H. Nadeau

We consider single production of leptoquarks (LQ's) at and colliders, for two values of the centre-of-mass energy, GeV and 1 TeV. We find that LQ's whi…

A Global Fit to Extended Oblique Parameters

C. P. Burgess, S. Godfrey, H. Konig +2

The STU formalism of Peskin and Takeuchi is an elegant method for encoding the measurable effects of new physics which couples to light fermions dominantly through its effects on e…

Higgs Bosons: Intermediate Mass Range at e+e- Colliders

V. Barger, K. Cheung, A. Djouadi +2

We elaborate on the production of the Standard Model Higgs particle at high-energy colliders through the reaction . Particular emphasis is put on th…

Beyond S, T and U

Ivan Maksymyk, C. P. Burgess, David London

The contribution to precision electroweak measurements due to TeV physics which couples primarily to the and bosons may be parameterized in terms of the three `oblique…

Two-Photon Decay Widths of Higgs Particles

A. Djouadi, M. Spira, P. M. Zerwas

Two--photon decays of Higgs bosons are important channels for the search of these particles in the intermediate mass range at the colliders LHC and SSC. Dynamical aspects of t…

Supersymmetric QCD corrections to quark pair production in e+ e- annihilation

A. Djouadi, M. Drees, H. König

We calculate supersymmetric QCD corrections (squark/gluino loops) to quark pair production in e+ e- annihilation, allowing for mixing between left- and right-handed squarks and tak…

Leptoquarks at Colliders

Helene Nadeau, David London

We consider single production of leptoquarks (LQ's) at colliders, for two values of the centre-of-mass energy, GeV and 1 TeV. LQ's with masses essentially up to…
