New Method For Extracting the Mass of the Top Quark From All-Jets Events

Six-jet events, arising from decays of $t\bar{t}$ pairs in which both tops decay into a $W$ boson and a $b$ quark, and both $W$s decay into quark-antiquark pairs, constitute a potentially rich source of completely reconstructable top quarks for mass extraction analyses. However, even when two of the jets are tagged as originating from b-quarks, the mass analysis is complicated by uncertainties in assigning the four other jets to their originating partons when assembling the $\bar{t}t$ pairs. We introduce and describe a new top mass extraction technique that directly addresses this complication, and present preliminary results from applying this technique to data recorded by the D0 experiment at the Fermilab Tevatron.
