Associated Production of Higgs Boson and $t\bar t$ at LHC

Understand

One of the future goals of the LHC is to precisely measure the properties of Higgs boson.

• The associated production of Higgs boson and the top quark pair is a promising process to investigate the related Yukawa interaction and the properties of Higgs.
• Compared with the pure scalar sector in the Standard Model, the Higgs sector contains both scalar and pseudoscalar in many new physics models, which makes the $t\bar t H$ interaction more complex and provides a variety of phenomena.
• To investigate the $t\bar t H$ interaction and the properties of Higgs, we study the top quark spin correlation observables at the LHC.
