Search for a Scalar Bottom Quark with Mass 3.5-4.5 GeV/$c^{2}$

TL;DR

This paper reports a search for a light scalar bottom quark in the mass range 3.5-4.5 GeV/c^2 using data collected at 10.52 GeV, finding no evidence for its existence.

Contribution

The study conducts a targeted search for a supersymmetric scalar bottom quark in a specific mass range using CLEO data collected below the B meson production threshold.

Findings

No evidence for the scalar bottom quark was observed.

The search sets upper limits on the production cross-section.

Results constrain supersymmetric models predicting light scalar bottom quarks.

Abstract

We report on a search for a supersymmetric $\tilde{B}$ meson with mass between 3.5 and 4.5 GeV/$c^2$ using 4.52 ${\rm fb}^{-1}$ of integrated luminosity produced at $\sqrt{s}=10.52$ GeV, just below the $e^+e^-\to B\bar{B}$ threshold, and collected with the CLEO detector. We find no evidence for a light scalar bottom quark.
