Abstract:

We present the first direct measurement of the top-quark mass using tt̄ events decaying in the hadronic τ+jets decay channel. Using data corresponding to an integrated luminosity of 2.2fb-1 collected by the CDF II detector in pp̄ collisions at √s=1.96TeV at the Fermilab Tevatron, we measure the tt̄ cross section, σtt̄, 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 σtt̄=8. 8±3.3(stat)±2.2(syst)pb and Mtop=172.7±9.3(stat) ±3.7(syst)GeV/c2. © 2012 American Physical Society.
