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…
Structure of the Effective Potential in Nonrelativistic Chern-Simons Field Theory
D. Caenepeel, F. Gingras, M. Leblanc +1
We present the scalar field effective potential for nonrelativistic self-interacting scalar and fermion fields coupled to an Abelian Chern-Simons gauge field. Fermions are non-mini…
Classical and Quantum Integrable Systems in $\wt{\gr{gl}}(2)^{+*}$ and Separation of Variables
John Harnad, P. Winternitz
Classical integrable Hamiltonian systems generated by elements of the Poisson commuting ring of spectral invariants on rational coadjoint orbits of the loop algebra $\wt{\gr{gl}}^{…
Induced term and photon mass generation in 3+1 dimensions
M. Leblanc, R. MacKenzie, P. K. Panigrahi +1
Analysing a 3+1 dimensional model with four-Fermi interactions, we show that topological $\BF$ terms (both abelian and non-abelian) can be induced radiatively by massive fermions a…
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…
Superconductivity in dimensions via Kosterlitz-Thouless Mechanism: Large-N and Finite-Temperature Analyses
R. MacKenzie, P. K. Panigrahi, S. Sakhi
We analyse a dimensional model with charged, relativistic fermions interacting through a four-Fermi term. Taking advantage of its large- renormalizability, the various pha…
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…
--Hypergeometric Functions in the Formalism of Free Fields
Alexei Morozov, Luc Vinet
We describe a representation of the --hypergeometric functions of one variable in terms of correlators of vertex operators made out of free scalar fields on the Riemann sphere.
{\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…
Two Dimensional Gauge Theoretic Supergravities
Daniel Cangemi, Martin Leblanc
We investigate two dimensional supergravity theories, which can be built from a topological and gauge invariant action defined on an ordinary surface. We concentrate on four models…
N-point Correlation Functions of the Spin-1 XXZ Model
A. H. Bougourzi, Robert A. Weston
We extend the recent approach of M. Jimbo, K. Miki, T. Miwa, and A. Nakayashiki to derive an integral formula for the N-point correlation functions of arbitrary local operators of…
Delicacies of the Mass Perturbation in the Schwinger Model on a Circle
M. B. Paranjape
The Hilbert bundle for the massless fermions of the Schwinger model on a circle, over the space of gauge field configurations, is topologically non-trivial (twisted). The correspon…
Isospectral Flow and Liouville-Arnold Integration in Loop Algebras
John Harnad
A number of examples of Hamiltonian systems that are integrable by classical means are cast within the framework of isospectral flows in loop algebras. These include: the Neumann o…
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…
Spontaneous Symmetry Breaking and the Renormalization of the Chern-Simons Term
Avinash Khare, R. B. MacKenzie, P. K. Panigrahi +1
We calculate the one-loop perturbative correction to the coefficient of the \cs term in non-abelian gauge theory in the presence of Higgs fields, with a variety of symmetry-breakin…

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…
