Direct constraints on the top-Higgs coupling from the 8 TeV LHC data

Understand

The LHC experiments have analyzed the 7 and 8 TeV LHC data in the main Higgs production and decay modes.

• Current analyses only loosely constrain an anomalous top-Higgs coupling in a direct way.
• In order to strongly constrain this coupling, the Higgs-top associated production is reanalyzed.
• Thanks to the strong destructive interference in the t-channel for standard model couplings, this process can be very sensitive to both the magnitude and the sign of a non-standard top-Higgs coupling.
