W+W− H production at lepton colliders : a new hope for heavy neutral leptons.

Baglio, J. and Pascoli, S. and Weiland, C. (2018) 'W+W− H production at lepton colliders : a new hope for heavy neutral leptons.', European physical journal C., 78 (10). p. 795.


We present the first study of the production of a Standard Model Higgs boson at a lepton collider in association with a pair of W bosons, e+e− → W+W− H, in the inverse seesaw model. Taking into account all relevant experimental and theoretical constraints, we find sizable effects due to the additional heavy neutrinos up to −38% on the total cross-section at a center-of-mass energy of 3 TeV, and even up to −66% with suitable cuts. This motivates a detailed sensitivity analysis of the process e+e− → W+W− H as it could provide a new, very competitive experimental probe of low-scale neutrino mass models.
