We report the first top-quark mass measurement that uses a cross-section constraint to improve the mass determination. This measurement is made with a dilepton tt̄ event candidate sample collected with the Collider Detector II at Fermilab. From a data sample corresponding to an integrated luminosity...

Čoahkkáigeassu:We report the first top-quark mass measurement that uses a cross-section constraint to improve the mass determination. This measurement is made with a dilepton tt̄ event candidate sample collected with the Collider Detector II at Fermilab. From a data sample corresponding to an integrated luminosity of 1.2fb-1, we measure a top-quark mass of 170.7-3.9+4.2(stat)±2.6(syst) ±2.4(theory)GeV/c2. The measurement without the cross-section constraint is 169.7-4.9+5.2(stat)±3.1(syst)GeV/c2. © 2008 The American Physical Society.
