D0 top analyses: Recent results on the properties of the sixth quark

The D0 collaboration updates measurements of the Standard Model top quark in pp collisions at {radical}s = 1.8 TeV at the Fermilab Tevatron, with a new data sample of approximately twice the integrated luminosity used for the discovery measurements ({approximately}100 pb{sup -1}). We observe 37 t{bar t} candidate events from seven decay modes with an expected background of 13.4 {+-} 3.0 events. We present a preliminary new top mass measurement of 170 {+-} 15 (stat.) {+-}10 (syst.) GeV/c{sup 2} using the single-lepton + jets decay modes. For the central value of our measured mass we calculate the production cross section to be 5.2 {+-} 1.8 pb. D{O} is also analyzing additional decay modes and we report preliminary results from two new channels
