Abstract

ATLAS found that none of their Standard Model simulations can describe the measured differential lepton distributions in their ttˉt \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 WWWW and bbbb, respectively. In this setup, the description of data is improved by at least 5.6σ5.6 \sigma.
