Abstract:

We report on a search for the pair production of scalar leptoquarks (LQ), using 191pb-1 of proton-antiproton collision data recorded by the CDF experiment during Run II of the Tevatron. The leptoquarks are sought via their decay into a neutrino and quark yielding missing transverse energy and several jets of large transverse energy. No evidence for LQ production is observed, and limits are set on σ(pp̄→LQLQ̄X→νν̄qq̄X). Using a next-to-leading order theoretical prediction of the cross section for LQ production, we exclude first-generation LQ in the mass interval 78 to 117GeV/c2 at the 95% confidence level for BR(LQ→νq)=100%. © 2005 The American Physical Society.

Abstract:

We report on a study of jet shapes in inclusive jet production in pp̄ collisions at s=1.96 TeV using the upgraded collider detector at Fermilab in Run II (CDF II) and based on an integrated luminosity of 170 pb-1. Measurements are carried out on jets with rapidity 0.1<|Yjet|<0.7 and transverse momentum 37GeV/c
