| dc.description.abstract | We present the first direct measurement of the top-quark mass using t¯t events decaying in the hadronic τ+jets decay channel. Using data corresponding to an integrated luminosity of
2.2 fb−1 collected by the CDF II detector in p¯p collisions at √s=1.96 TeV at the Fermilab Tevatron, we measure the t¯t cross section, σt¯t, and the top-quark mass, Mtop. We extract
Mtop from a likelihood based on per-event probabilities calculated with leading-order signal and background matrix elements. We measure σt¯t=8.8±3.3(stat)±2.2(syst) pb and Mtop=172.7±9.3(stat)±3.7(syst) GeV/c2. | es_ES |
