Extended Gauge Models at e+e- Colliders

A. Djouadi

We summarize the potential of high--energy $\ee$ linear colliders for discovering, and in case of discovery, for studying the signals of extended gauge models. We will mainly focus…

Remarks on the UA4/2 dσ/dt and on the Asymptotic σ_T(s) Behavior

Kyungsik Kang, Pierre Valin

We find that the UA4/2 measurements on the real part of the forward scattering amplitude and total cross section are consistent with each other and also with the standar…

Particle Production in a Hadron Collider Rapidity Gap: The Higgs Case

Jean-Rene Cudell, Oscar F. Hernandez

Production of rare particles within rapidity gaps has been proposed as a background-free signal for the detection of new physics at hadron colliders. No complete formalism accounts…

Inverse Neutrinoless Double Beta Decay Revisited

G. Bélanger, F. Boudjema, D. London +1

We critically reexamine the prospects for the observation of the lepton-number-violating process $\eeWW$ using the option of a high-energy collider (NLC).…

CP Violation and Flavour Mixing in the Standard Model

A. Ali, D. London

We review and update the constraints on the parameters of the quark flavour mixing matrix in the standard model and estimate the resulting CP asymmetries in decays, t…

Baby Skyrmion Strings

T. Gisiger, M. B. Paranjape

We provide analytical and numerical evidence of the existence of classically stable, string-like configurations in a 2+1 dimensional analog of the Skyrme model. The model contains…

On Non-Standard Couplings among the Electroweak Vector Bosons

C. Grosse-Knetter, I. Kuss, D. Schildknecht

Application of a Stueckelberg transformation allows one to connect various Lagrangians which have been independently proposed for non-standard couplings. We discuss the reduction o…

Integrating out the Standard Higgs Field in the Path Integral

Stefan Dittmaier, Carsten Grosse-Knetter

We integrate out the Higgs boson in the electroweak standard model at one loop and construct a low-energy effective Lagrangian assuming that the Higgs mass is much larger than the…

HIGGS BOSON PRODUCTION AT THE LHC

M. Spira, A. Djouadi, D. Graudenz +1

Gluon fusion is the main production mechanism for Higgs particles at the LHC. We present the QCD corrections to the fusion cross sections for the Higgs boson in the Standard Model,…

Broken SU(3) Symmetry in Two-Body B Decays

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

The decays of mesons to two-body hadronic final states are analyzed within the context of broken flavor SU(3) symmetry, extending a previous analysis involving pairs of light p…

ELECTROWEAK PENGUINS AND TWO-BODY B DECAYS

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

We discuss the role of electroweak penguins in decays to two light pseudoscalar mesons. We confirm that the extraction of the weak phase through the isospin analysis involv…

NEW PARTICLES AND INTERACTIONS

A. Djouadi, J. Ng, T. G. Rizzo

We analyze the manifestations of new matter particles predicted by models of new physics beyond the Standard Model, at present and future high--energy colliders. We consider both t…

One-Loop Effects of a Heavy Higgs Boson: a Functional Approach

Stefan Dittmaier, Carsten Grosse-Knetter

We integrate out the Higgs boson in the electroweak standard model at one loop, assuming that it is very heavy. We construct a low-energy effective Lagrangian, which parametrizes t…

ANOMALOUS GAUGE BOSON INTERACTIONS

H. Aihara, T. Barklow, U. Baur +9

We discuss the direct measurement of the trilinear vector boson couplings in present and future collider experiments. The major goals of such experiments will be the confirmation o…

How To Use SU(3)-Flavor Symmetry to Extract CP Violating Phases and Strong Phase Shifts at CLEO

Oscar F. Hernandez

After a short introduction to the SM picture of CP violation, we discuss recent work on how to use SU(3) flavor symmetry, along with some dynamical approximations, to extract the C…

Deriving Non-decoupling Effects of Heavy Fields from the Path Integral: a Heavy Higgs Field in an SU(2) Gauge Theory

Stefan Dittmaier, Carsten Grosse-Knetter

We describe a method to remove non-decoupling heavy fields from a quantized field theory and to construct a low-energy one-loop effective Lagrangian by integrating out the heavy de…

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

A. Arhrib, M. Capdequi-Peyranere, A. Djouadi

We calculate the QCD radiative corrections to the production of supersymmetric scalar partners of quarks in e+e- annihilation. We include both the standard gluonic corrections and…
