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

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