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, σ tt̄, and the top-quark mass, M top. We extract M top from a likelihood based on per-event probabilities calculated with leading-order signal and background matrix elements. We measure σ tt̄=8. 8±3.3(stat)±2.2(syst)pb and M top=172.7±9.3(stat) ±3.7(syst)GeV/c2. © 2012 American Physical Society.
