Effective Chiral Lagrangians with an SU(3)-Broken Vector-Meson Sector
A. Bramon, A. Grau, G. Pancheri
The accuracy of effective chiral lagrangians including vector-mesons as (hidden symmetry) gauge fields is shown to be improved by taking into account SU(3)-breaking in the vector-m…
Patterns of quark mass matrices in a class of Calabi-Yau models
F. del Aguila, M. Masip, L. da Mota
We study a class of superstring models compactified in the 3-generation Calabi-Yau manifold of Tian and Yau. Our analysis includes the complete -singlet sector, which has been…
Non Standard Tau Pair Production in Two Photon Collisions at LEP II and Beyond
Fernando Cornet, J. I. Illana
We study the sensitivity of LEP II and NLC, via two photon collisions, to the effects of anomalous couplings. We also discuss some CP-odd observables that can be us…
Model-independent determination of couplings at LEP 200
F. del Aguila
All couplings of a new heavy gauge boson to ordinary fermions can be determined in a model-independent way at a large collider for large enough statistics. No such determi…
The Physics of Z' bosons
F. del Aguila
In these lectures we review the simplest gauge extensions of the standard model, and the present and future limits on new weak interactions.
Diagnostic Power of Future Colliders for Z'Couplings to Quarks and Leptons: e+e- versus pp Colliders
F. del Aguila, M. Cvetic
We study the diagnostic power of future colliders with GeV (the New Large Collider ()) for a model independent determination of the gauge cou…
