A precise measurement of the top quark mass

PDF Version Also Available for Download.

Description

We present a measurement of the mass of the top quark using data from proton-antiproton collisions recorded at the CDF experiment in Run II of the Fermilab Tevatron. Events are selected from the single lepton plus jets final state (t{bar t} {yields} W{sup +}bW{sup -}{bar b} {yields} {ell}{nu}bq{bar q}{prime}{bar b}). The top quark mass is extracted using a calculation of the probability density for a t{bar t} final state to resemble a data event. This probability density is a function of both top quark mass and energy scale of calorimeter jets, constrained in situ with the hadronic W boson mass. ... continued below

Description

We present a measurement of the mass of the top quark using data from proton-antiproton collisions recorded at the CDF experiment in Run II of the Fermilab Tevatron. Events are selected from the single lepton plus jets final state (t{bar t} {yields} W{sup +}bW{sup -}{bar b} {yields} {ell}{nu}bq{bar q}{prime}{bar b}). The top quark mass is extracted using a calculation of the probability density for a t{bar t} final state to resemble a data event. This probability density is a function of both top quark mass and energy scale of calorimeter jets, constrained in situ with the hadronic W boson mass. Using 167 events observed in 955 pb{sup -1} integrated luminosity, we achieve the single most precise measurement of top quark mass to date of 170.8 {+-} 2.2 (stat.) {+-} 1.4 (syst.) GeV/c{sup 2}, where the quoted statistical uncertainty includes uncertainty from the determination of the jet energy scale.
