Ultra-light scalar fields may explain the nature of the dark matter in our universe. If such scalars couple quadratically to particles of the Standard Model the scalar acquires an effective mass which depends on the local matter energy density. The changing mass causes the field to deviate from its cosmological value in experimental environments. In this work we show that the presence of a...
We propose a novel link between the hierarchy problem and Weakly Interacting Massive Particles (WIMPs), suggesting that the small mass of the Higgs boson arises from the universe’s WIMP-induced proximity to the critical boundary of a phase transition. Intriguingly, such a requirement aligns with a split spectrum of new light fermions and heavy bosons expected from naturalness, and overlaps...
