Enhancing the ttH signal through top-quark spin polarization effects at the LHC
(2016) In Nuclear and Particle Physics Proceedings 273-275. p.721-726- Abstract
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.
