A measurement of the top quark mass (Mtop) in the all-hadronic decay channel is presented. It uses 5.8 fb−1 of p.p data collected with the CDF II detector at the Fermilab Tevatron Collider. Events with six to eight jets are selected by a neural network algorithm and by the requirement that at least one of the jets is tagged as a b-quark jet. The measurement is performed with a likelihood fit technique, which simultaneously determines Mtop and the jet energy scale (JES) calibration. The fit yields a value of Mtop = 172.5±1.4(stat)±1.0(JES)±1.1(syst) GeV/c2.

Abstract
A measurement of the top quark mass (Mtop) in the all-hadronic decay channel is presented. It uses 5.8 fb−1 of p.p data collected with the CDF II detector at the Fermilab Tevatron Collider. Events with six to eight jets are selected by a neural network algorithm and by the requirement that at least one of the jets is tagged as a b-quark jet. The measurement is performed with a likelihood fit technique, which simultaneously determines Mtop and the jet energy scale (JES) calibration. The fit yields a value of Mtop = 172.5±1.4(stat)±1.0(JES)±1.1(syst) GeV/c2.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
