Search for Leptoquarks with the D0 detector

TL;DR

This paper reports on a search for leptoquarks using data from the D0 detector at the Tevatron, setting lower mass limits due to no observed signals.

Contribution

First search for leptoquarks at the D0 detector with new data, establishing mass exclusion limits in proton-antiproton collisions.

Findings

No evidence for leptoquark production was observed.

Lower mass limits for leptoquarks were set.

Analysis used 1-4 inverse femtobarns of data.

Abstract

We report on D0 searches for leptoquarks (LQ) predicted in extended gauge theories and composite models to explain the symmetry between quarks and leptons. Data samples obtained with the D0 detector from proton-antiproton collisions at a center-of-mass energy of 1.96 TeV corresponding to intergrated luminosities of 1--4 inverse-fb were analyzed. No evidence for the production of such particles were observed and lower limits on leptoquark masses are set.
