Higgs physics at future lepton colliders.

Various proposals of electron and muon colliders have been put forward for precision studies of the Higgs properties. It is shown that in both cases of Higgs resonant production through a muon collider, and associated HZ production in a electron–positron collider sizeable QED radiative effects must be carefully taken into account for the precise measurements of the decay channels of the Higgs particle.
