We consider the process $p p \to t {\bar t} H$. This process can give rise tomany signatures of the Higgs boson. The signatures can have electrons, muonsand jets. We consider the signatures that have two electrons/muons and jets.Tagging of a tau jet and a bottom jet can help reduce the backgroundssignificantly. In particular, we examine the usefulness of the signatures"isolated 2 electrons/muons + a bottom jet + a tau jet", "isolated 2electrons/muons + 2 tau jets", "isolated 2 electrons/muons + 2 bottom jets + atau jet", and "isolated 2 electrons/muons + a bottom jet + 2 tau jets". We findthat signatures with two tau jets are useful. The signatures with one tau jetare also useful, if we restrict to same-sign electrons/muons. Theserequirements reduce the backgrounds due the process with Z-bosons + jets andthe production of a pair of top quarks. We show that these signatures may bevisible in the run II of the Large Hadron Collider.
