The second biggest background is a two step decay in which a $t$ and a $\overline{t}$ which both decay to the corresponding b-quark and a W-boson which subsequently decays to a muon and its neutrino (to be reffered to as $t\overline{t}$):  $t \begin{equation}  t  \overline{t} \rightarrow W^+ W^- b \overline{b} \rightarrow \mu^+ \mu^- b \overline{b} \nu \overline{\nu} *$ *  \end{equation}  While these two contribute the most to the background signal, there are 6 other proceses which have signatures that can resemble the target decay after taking into consideration fakes and mismeasurements. Those processes are:
