In this work, we study the production of Higgs boson pairs at next-to-next-to-leading order in QCD matched to parton showers, using \textsc{Geneva} framework and working heavy-top-limit approximation. This includes resummation large logarithms zero-jettiness $\mathcal{T}_0$ up next-to-next-to-next-to-leading-log accuracy. process features an extremely momentum transfer, which makes its particularly relevant for matching schemes such as that employed \textsc{Geneva}, where a variable different from used ordering shower is used. To further effect, extend original interface designed \textsc{Pythia8} include other \textsc{Dire} \textsc{Sherpa}.
