Charting Dark Matter down to the neutrino floor/fog in the 2HD+a scenario
Giorgio Arcadi, Abdelhak Djouadi, Stefano Profumo
Next-generation direct detection experiments will probe dark matter (DM) scattering cross-sections deep into the neutrino fog, the regime where coherent neutrino scattering becomes…
Interpreting the current Higgs excesses at the LHC in the 2HD+a framework
Giorgio Arcadi, Abdelhak Djouadi
There are several excesses of events in current LHC data, yet not exceeding the level of significance which would make them to be considered as firm. They point to the possibility…
Contrasting Pseudoscalar Higgs and Toponium States at the LHC and Beyond
Abdelhak Djouadi, John Ellis, Jeremie Quevillon
We discuss ways to discriminate at hadron colliders between a quasi-bound toponium state and a pseudoscalar Higgs boson A, as predicted in many extensions of the Standard Model. We…
A complete effective field theory for dark matter
Juan Carlos Criado, Abdelhak Djouadi, Manuel Perez-Victoria +1
We present an effective field theory describing the relevant interactions of the Standard Model with an electrically neutral particle that can account for the dark matter in the Un…
