摘要：
Determination of trilinear Higgs coupling (lambda(HHH) = kappa lambda(SM)(HHH)) through Higgs pair productions is a major motivation for the LHC high-luminosity phase. We perform a detailed collider simulation to explore the potential of measuring lambda(HHH) in the VHH (V = W, Z) production at the high-luminosity Large Hadron Collider. We find that the trilinear Higgs coupling in the standard model (lambda(SM)(HHH)) can be measured at the level of 1.3 sigma. Combining with the gluon fusion, vector boson fusion, and t (t) over bar HH channels, lambda(SM)(HHH) is expected to be measured at the level of 3.13 sigma. If no evidence of Higgs pair productions is observed, the VHH production, together with the gluon fusion channel, imposes a bound of 0.5 <= kappa <= 2.2 at the 95% confidence level.
