Measurement of the Top Quark Mass Using the Invariant Mass of Lepton Pairs in Soft Muon b-tagged Events

The CDF Collaboration, T. Aaltonen

We present the first measurement of the mass of the top quark in a sample of $t\bar{t}\to \ell \bar{\nu }b\bar{b}q\bar{q}$ events (where $\ell =e$, $\mu$) selected by identifying jets co…
