TL;DR: In this paper, the authors show that leptoquarks with quantum numbers of (eb) and (et) compounds can be generated in electron-gluon collisions, and their production rates and signatures are discussed for HERA energies and beyond.
Abstract: Leptoquarks with quantum numbers of (eb) and (et) compounds can be generated in electron-gluon collisions. Production rates and signatures are discussed for HERA energies and beyond.

TL;DR: In this paper, the lightest excited particles (LEPs) were used for a systematic search of excited neutrinos in the fermionic sector and their signatures and production were presented.
38 citations
TL;DR: The forward-backward asymmetry of b-quark jets in Z decays can be exploited to determine sin2θW very accurately as mentioned in this paper, and the forward-forward asymmetry can be used to determine the sin 2 θW.
Abstract: The forward-backward asymmetry ofb-quark jets inZ decays can be exploited to determine sin2θW very accurately. Electroweak and QCD corrections are analysed in detail.

TL;DR: In this article, a sum rule was derived for the top mass in terms of a special combination of quantities that might be measured in a near future at LEP, such as the ratio of the Z width into b quarks to the width into charged leptons, and the forward-backward asymmetry for b quark production on Z resonance.

TL;DR: In this article, the virtual effects due to the minimal supersymmetric two-Higgs doublets model on top of the Z resonance were analyzed and it was shown that the precise measurement of the partial decay width into b quarks and the forward-backward asymmetry for b jets, which will be performed at LEP, may allow for indirect signals of super-ymmetric nature.

TL;DR: In this paper, the authors proposed a new and rather unbiased way of determining the value of the strong coupling constant α s if transversally polarized electron-positron beams were available at LEP1.
