Abstract

Abstract: We study contributions to (Formula presented.) in models with a new Higgs boson, H, and a neutral lepton, ν₄, with couplings H (Formula presented.) and W (Formula presented.) through the process (Formula presented.). Contrary to naive expectations, we find that contributions to pp → W W can be very large while satisfying constraints from standard H → W W and H → γγ searches. Even the excess observed by ATLAS in pp → W W , if taken at face value, can be easily accommodated. The various kinematic distributions fit nicely the experimentally determined ones. This scenario can arise for example in a two Higgs doublet model with vectorlike leptons.
