Higgs production in association with a Z boson at TeV-scale lepton colliders

Hiroyuki Furusato, Satsuki Hosoya, Kentarou Mawatari +1

We study the $l^{-} l^{+} \to I^½ I^ˉ ½ Z h$ process for future lepton colliders, whose cross section becomes larger than that for $l^{-} l^{+} \to Z h$ in the energy region above a few TeV. We cl…

W-boson pair production at lepton colliders in the Feynman-diagram gauge

Hiroyuki Furusato, Kentarou Mawatari, Yutaro Suzuki +1

We calculate helicity amplitudes for $e^{-} e^{+} \to W^{-} W^{+}$ analytically in the Feynman-diagram (FD) gauge. We show that, unlike in the unitary gauge, there is no energy growth of the…
