Query: Multiphoton signals of a (96 GeV?) stealth boson   Cascade decays of new scalars into final states with multiple photons and
possibly quarks may lead to distinctive experimental signatures at high-energy
colliders. Such signals are even more striking if the scalars are highly
boosted, as when produced from the decay of a much heavier resonance. We study
this type of events within the framework of the minimal stealth boson model, an
anomaly-free $\text{U}(1)_{Y'}$ extension of the Standard Model with two
complex scalar singlets. It is shown that, while those signals may have cross
sections that might render them observable with LHC Run 2 data, they have
little experimental coverage. We also establish a connection with a CMS excess
observed in searches for new scalars decaying into diphoton final states near
96 GeV. In particular, we conclude that the predicted multiphoton signatures
are compatible with such excess.
