The phenomenological constraints on extra neutral gauge bosons at present and at future
colliders are reviewed. Special attention is paid to the influence of radiative corrections …

The current status of measurements of the nucleon structure functions and their
understanding is reviewed. The fixed target experiments E665, CCFR and NMC and the …

We discuss experimental implications of extending the gauge structure of the standard
model to include an additional U (1) interaction broken at or near the weak scale. We work …

We discuss a model in which the third generation fermions undergo a different SU (2) weak
interaction from the first two generation fermions. In general, a flavor changing neutral …

In this paper, we investigate the possibility of explaining both the R b excess and the R c
deficit reported by the CERN LEP experiments through Z− Z′ mixing effects. We have …

We consider electroweak symmetry breaking in supersymmetric models with an extra
nonanomalous U (1)′ gauge symmetry and an extra standard-model singlet scalar S. For …

A flavor-universal extension of the strong interactions was recently proposed in response to
the apparent excess of high-E T jets in the inclusive jet spectrum measured at the Fermilab …

We study the electroweak and U (1)′ symmetry breaking patterns in models with the
particle content of supersymmetric E 6, including standard model singlets S and exotic …

Recent results from CDF indicate that the inclusive cross section for jets with Er> 200 GeV is
significantly higher than that predicted by QCD. We describe here a simple flavor-universal …

A bstract Most of the existing analyses of flavour changing neutral current processes (FCNC)
in the 331 models, based on the gauge group SU (3) C× SU (3) L× U (1) X, are fully …
