  We outline a new explanation for the primordial density perturbations in
cosmology. Dimension zero fields are a minimal addition to the Standard Model
of particle physics: if the Higgs doublet is emergent, they cancel the vacuum
energy and both Weyl anomalies without introducing any new particles.
Furthermore, the cancellation explains why there are three generations of
elementary particles, including RH neutrinos. We show how quantum zero point
fluctuations of dimension zero fields seed nearly scale-invariant, Gaussian,
adiabatic density perturbations. We calculate the amplitude of the primordial
perturbations in terms of Standard Model couplings and find a result consistent
with large scale observations. Subject to two key theoretical assumptions, both
the amplitude and the tilt we calculate agree with the observed values, with no
free parameters.
