Search for Second and Third Generation Leptoquarks Including Production via Technicolor Interactions in $p \bar{p}$ collisions at $\sqrt{s}=1.8$ TeV

TL;DR

This paper searches for second and third generation leptoquarks produced via technicolor interactions in proton-antiproton collisions, setting mass limits due to no observed excess over Standard Model predictions.

Contribution

It introduces a search for scalar leptoquarks from technicolor models in collider data, establishing new mass limits for these particles.

Findings

No significant excess observed over Standard Model expectations.

Mass limits set for second and third generation leptoquarks.

Results constrain technicolor-based leptoquark models.

Abstract

We report the results of a search for second and third generation leptoquarks using 88 ${pb}^{-1}$ of data recorded by the Collider Detector at Fermilab. Color triplet technipions, which play the role of scalar leptoquarks, are investigated due to their potential production in decays of strongly coupled color octet technirhos. Events with a signature of two heavy flavor jets and missing energy may indicate the decay of a second (third) generation leptoquark to a charm (bottom) quark and a neutrino. As the data is found to be consistent with Standard Model expectations, mass limits are determined.
