2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/215200We 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.15 pages, 2 figures. Submitted for publication in Phys. Rev.
