Understand

The top quark has a large Yukawa coupling with the Higgs boson.

In the usual extensions of the standard model the Higgs sector includes extra scalars, which also tend to couple strongly with the top quark.
Unlike the Higgs, these fields have a natural mass above 2m_t, so they could introduce anomalies in ttbar production at the LHC.
We study their effect on the ttbar invariant mass distribution at sqrt{s}=7 TeV.
