Constraining the Higgs valence contribution in the proton

Understand

Non-perturbative gauge-invariance under the strong and the weak interactions dictates that the proton contains a non-vanishing valence contribution from the Higgs particle.

• By introducing an additional parton distribution function (PDF), we investigate the experimental consequences of this prediction.
• The Herwig 7 event generator and a parametrized CMS detector simulation are used to obtain predictions for a scenario amounting to the LHC Run II data set.
• We use those to assess the impact of the Higgs PDF on the pp->ttbar process in the single lepton final state.
