Differential $e\mu bb$ Cross-Sections and New Higgses at the Electroweak Scale

ATLAS found that none of their Standard Model simulations can describe the measured differential lepton distributions in their $t\bar{t}$ analysis reasonably well. Therefore, we study the possibility that this measurement has a new physics contamination. We consider a benchmark model motivated by the indications for di-photon resonances: A heavy scalar decays into two lighter Higgs bosons with masses of 152,GeV and 95,GeV, with subsequent decay to $WW$ and $bb$, respectively. In this setup, the description of data is improved by at least $5.6\sigma$.
