Search for bottom squarks in pbarp collisions at sqrt(s)=1.8 TeV

TL;DR

This paper reports a search for bottom squarks in proton-antiproton collisions at 1.8 TeV, setting limits on their production cross section based on data from the D0 detector at Fermilab.

Contribution

It presents the first limits on bottom squark production cross section in pbarp collisions at this energy using the D0 detector.

Findings

No evidence of bottom squark production was observed.

Limits were set on the production cross section as a function of bottom squark and LSP masses.

The results constrain supersymmetric models predicting bottom squarks.

Abstract

We report on a search for bottom squarks produced in pbarp collisions at sqrt(s) = 1.8 TeV using the D0 detector at Fermilab. Bottom squarks are assumed to be produced in pairs and to decay to the lightest supersymmetric particle (LSP) and a b quark with branching fraction of 100%. The LSP is assumed to be the lightest neutralino and stable. We set limits on the production cross section as a function of bottom squark mass and LSP mass.
