Search for Second and Third Generation Leptoquarks at CDF

TL;DR

This paper reports a search for second and third generation leptoquarks at Fermilab, analyzing collision data to set mass limits due to no observed excess over Standard Model predictions.

Contribution

It introduces a search for scalar leptoquarks via technipions 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.

Analysis demonstrates the feasibility of detecting leptoquarks through heavy flavor jets and missing energy.

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.
