Measuring the Higgs-Vector boson Couplings at Linear $e^{+} e^{-}$ Collider

Understand

We estimate the accuracy with which the coefficient of the CP even dimension six operators involving Higgs and two vector bosons (HVV) can be measured at linear $e^+ e^-$ colliders.

• Using the optimal observables method for the kinematic distributions, our analysis is based on the five different processes.
• First is the WW fusion process in the t-channel ($e^+e^- \to \bar{\nu}_e \nu_e H$), where we use the rapidity y and the transverse momentum $\pT$ of the Higgs boson as observables.
• Second is the ZH pair production process in the s-channel, where we use the scattering angle of the Z and the Z decay angular distributions, reproducing the results of the previous studies.
