Hadronic production of top-quark pairs in association with a pair of leptons in the POWHEG BOX framework

Margherita Ghezzi, Barbara Jager, Santiago Lopez Portillo Chavez +2

We present an implementation of $t\bar{t}{\ell }^{+}{\ell }^{-}$ ($\ell =e,\mu$) hadronic production at next-to-leading order in QCD matched to parton-shower event generators in the POWHEG BOX…
