Improved Measurement of ttZ Couplings at the LHC

U. Baur, A. Juste, D. Rainwater +1

We consider QCD tt~Z production at the LHC with Z->\barννand all-hadronic tt~ decays, i.e. pp -> p_T(miss)bb~+4 jets, as a tool to measure ttZ couplings. This channel has a signifi…

Top Quark Measurements

A. Juste

Ten years after its discovery at the Tevatron collider, we still know little about the top quark. Its large mass suggests it may play a key role in the mechanism of Electroweak Sym…
