Tricking Landau–Yang: How to obtain the diphoton excess from a vector resonance
We show that contrary to naive expectations the recently observed diphoton excess can be explained by a vector resonance, which decays to a photon and a light scalar s, followed by a decay of the scalar into two photons: Z′→γs→3γ. As the two photons from the scalar decay are highly boosted, the expe...
