Search for third generation scalar leptoquarks decaying into tau b

TL;DR

This paper reports a search for third generation scalar leptoquarks decaying into a bottom quark and a tau lepton, setting a new lower mass limit based on data from the Fermilab Tevatron Collider.

Contribution

First search for scalar third generation leptoquarks decaying into tau and b quark at the Tevatron, establishing a 210 GeV mass lower limit.

Findings

No evidence of leptoquarks found within the analyzed data.

Set a 95% confidence level lower mass limit of 210 GeV.

Utilized 1.05 fb^-1 of data from the D0 detector.

Abstract

We have searched for third generation leptoquarks (LQ3) using 1.05 inverse femtobarns of data collected with the D0 detector at the Fermilab Tevatron Collider operating at sqrt(s)=1.96 TeV. We set a 95% C.L. lower limit of 210 GeV on the mass of a scalar LQ3 state decaying solely to a b quark and a tau lepton.
