The price to pay is additional matter to enhance the $\gamma\gamma$ rate, and a peculiar pattern for the lepton Yukawa couplings. We add TeV scale vector-like fermions and find parameter space consistent with both excesses, as well as with Higgs and electroweak precision observables. %G English %2 https://hal.in2p3.fr/in2p3-01269676/document %2 https://hal.in2p3.fr/in2p3-01269676/file/Bizot2016_Article_TwoHiggsDoubletsToExplainTHeEx.pdf %L in2p3-01269676 %U https://hal.in2p3.fr/in2p3-01269676 %~ IN2P3 %~ CNRS %~ UNIV-LYON1 %~ L2C %~ MIPS %~ UNIV-MONTPELLIER %~ AMIDEX %~ IP2I %~ UDL %~ UNIV-LYON %~ CMS %~ IPM %~ PHABIO %~ MANOIR %~ THEORIE %~ COSMOLOGIE %~ MATNUC %~ NEUTRINOS_IP2I %~ ONDES_GRAVITATIONNELLES %~ ANR %~ MATICE %~ UM-2015-2021
