In the framework of the littlest Higgs($LH$) model, we consider the processes $e^{+}e^{-}\to\nu\bar{\nu}H^{0}$ and $e^{+}e^{-}\to W^{*}W^{*}\nu\bar{\nu}\to\nu\bar{\nu}t\bar{t}$, and calculate the contributions of new particles to the cross…

A future e+e- collider, such as the ILC or CLIC, would allow the Higgs sector to be probed with a precision significantly beyond that achievable at the High-Luminosity LHC. A central part of the Higgs programme at an e+e- collider is the…
Inclusive Higgs boson pair production through the mechanism of gauge boson fusion e^{+} e^{-} -> V* V* -> h h + X (V=W,Z) in the general Two-Higgs-Doublet Model (2HDM), with h=h^0,H^0,A^0,H^{\pm}, is analyzed at order \alpha^4_{ew} in the…
Measuring the Higgs couplings accurately at colliders is one of the best routes for finding physics Beyond the Standard Model (BSM). If the measured couplings deviate from the SM predictions, then this would give rise to energy-growing…
