In this report we survey the low-energy phenomenological implications of superstring-
inspired E 6 models. The motivation for such models is reviewed. New particles including …

In electroweak models, radiative corrections to the scalar potential can have significant
consequences. In the standard model, they can destabilize the standard model vacuum; the …

The minimal supersymmetric standard model contains two Higgs doublets which must mix
via a mass parameter whose magnitude remains to be explained. We explore an extension …

We investigate QCD corrections to the cross section and differential distributions for p+ p→
Q+ Q+ X, where Q and Q are heavy quarks. We calculate the order-α s corrections to the …

The Higgs sector of supersymmetric models with an additional SU (2)× U (1) Y singlet or an
additional pair of Higgs doublet superfields is investigated. It is shown that in the model with …

If the top quark mass is above 86 GeV, then a stringent lower bound on the mass of the
Higgs boson arises from the requirement of vacuum stability. We calculate the bound as …

An extensive study of production and decay properties of charged and neutral Intermediate
Vector Bosons (IVB) at the CERN proton-antiproton collider is presented. Intermediate …

The top quark, discovered at the FERMILAB TEVATRON collider in 1995, is the heaviest
known elementary particle. Today, ten years later, still relatively little is known about its …

Renormalization-group equations and asymptotic conditions are used to obtain top-quark
mass predictions. In the standard model with an explicit Higgs mechanism, our analysis …

The total cross sections for top, bottom and charm production in hadronic collisions at
energies of practical interest are studied using a recent complete calculation of the next-to …
