No-scale supergravity is a leading candidate for an effective theory that describes nature at
energies below the Planck scale (mp≌ 10 19 GeV). Its virtues, such as an automatically …

Abstract During 1989 and 1990 over 200 000 hadronic and leptonic events, corresponding
to about 8.5 pb− 1 of data, were collected in a scan of the Z peak using the ALEPH detector …

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 …

The present experimental constraints on the existence of light charged and neutral
electroweak scalar particles are summarized. Within the context of an explicit extended …

The JADE detector has been operated at the e~ e storage ring PETRA [3] situated at DESY,
Hamburg (Gennany) since 1979 and will continue taking data until the end of PETRA …

Evidence for pair production of a new particle consistent with the standard-model top quark
has been reported recently by groups studying proton-antiproton collisions at 1.8 TeV center …

In a general supergravity theory, with minimal particle content, we describe the area of the
parameter space that gives rise to a massive, stable neutralino χ, with a cosmologically …

The top quark is the heaviest elementary particle observed to date. Its large mass makes the
top quark an ideal laboratory to test predictions of perturbation theory concerning heavy …

We present phenomenological constraints on, and experimental predictions from, the
minimal low energy model extracted from the superstring which appears able to generate …

Electrons and positrons in storage rings have natural polarization which is perpendicular to
the beam direction. Effects of the transverse polarization to azimuthally integrated cross …
