Absolute mass limits of the gaugino-Higgsino sector in the minimal supersymmetric model from data from the CERN collider LEP and the Fermilab Tevatron.

Abstract

Absolute mass limits of the gaugino-Higgsino sector in the minimal supersymmetric model are extracted from the data on $Z$ at the CERN ${e}^{+}{e}^{\ensuremath{-}}$ collider LEP and the gluino ($\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{g}$) search at the Collider Detector at Fermilab: ${m}_{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{g}}>132$, ${m}_{{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{Z}}_{1}}>18.4$, ${m}_{{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{Z}}_{2}}>45$, ${m}_{{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{Z}}_{3}}>70$, ${m}_{{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{Z}}_{4}}>108$, and ${m}_{{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{W}}_{2}}>99$ GeV. The ${\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{Z}}_{k}$ and ${\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{W}}_{2}$ are neutralinos and a heavier chargino.
