Summary, in English

We consider the impact of the tt spin correlations in the Higgs boson production in association with top quark pairs pp→ttH and in the corresponding backgrounds. We study the H→bb and H→γγ decay modes. We show that retaining the tt spin-correlation effects could significantly improve the LHC sensitivity to the ttH signal, particularly in the H→γγ channel.
