Measuring Higgs Couplings at a Linear Collider

Markus Klute, Remi Lafaye, Tilman Plehn, Michael Rauch, Dirk Zerwas

Abstract

Higgs couplings can be measured at a linear collider with high precision. We estimate the uncertainties of such measurements, including theoretical errors. Based on these results we show an extrapolation for a combined analysis at a linear collider and a high-luminosity LHC.

  • Figure 1: Expected precision for Higgs coupling measurements at the HL-LHC, ILC at 250 GeV and their combination. For the latter we also show the fit including $\Delta_c$. The inner bars for HL-LHC denote a scenario with improved experimental systematic uncertainties.
  • Figure 2: Expected precision for Higgs couplings measurements at the HL-LHC, ILC up to 500 GeV and their combination. For the latter we also show the fit including $\Delta_c$. The inner bars for HL-LHC denote a scenario with improved experimental systematic uncertainties.
