Primordial black holes as dark matter through Higgs field criticality

Journal Article Passaglia, Samuel ; Hu, Wayne ; Motohashi, Hayato - Physical Review. D.

In this work, we study the dynamics of a spectator Higgs field which stochastically evolves during inflation onto near-critical trajectories on the edge of a runaway instability. We show that its fluctuations do not produce primordial black holes in sufficient abundance to be the dark matter, nor do they produce significant second-order gravitational waves. First we show that the Higgs produces larger fluctuations on cosmic microwave background scales than on primordial black hole (PBH) scales, itself a no go for a viable PBH scenario. Then we track the superhorizon perturbations nonlinearly through reheating using themore »« less

Stochastic evolution of scalar fields with continuous symmetries during inflation

Journal Article Adshead, Peter ; Pearce, Lauren ; Shelton, Jessie ; ... - Physical Review D

During inflation, scalar fields with masses less than the Hubble scale acquire vacuum expectation values (VEVs) via stochastic processes driven by quantum fluctuations. For nearly massless spectator scalars transforming nontrivially under a continuous symmetry group, we demonstrate that the evolution of the VEV depends on the dimensionality of the scalar field space. Fields in larger representations both attain larger vacuum expectation values and converge more rapidly to equilibrium. We present an argument demonstrating how this higher-dimensional evolution can be obtained in unitary gauge for fields transforming under local symmetries with a mass gap that is small compared to the Hubblemore »« less

Cosmological gravitational particle production of massive spin-2 particles

Journal Article Kolb, Edward W. ; Ling, Siyang ; Long, Andrew J. ; ... - Journal of High Energy Physics (Online)

The phenomenon of cosmological gravitational particle production (CGPP) is expected to occur during the period of inflation and the transition into a hot big bang cosmology. Particles may be produced even if they only couple directly to gravity, and so CGPP provides a natural explanation for the origin of dark matter. In this work we study the gravitational production of massive spin-2 particles assuming two different couplings to matter. We evaluate the full system of mode equations, including the helicity-0 modes, and by solving them numerically we calculate the spectrum and abundance of massive spin-2 particles that results from inflationmore »« less

Generalized slow roll in the unified effective field theory of inflation

Journal Article Motohashi, Hayato ; Hu, Wayne - Physical Review D

In this paper, we provide a compact and unified treatment of power spectrum observables for the effective field theory (EFT) of inflation with the complete set of operators that lead to second-order equations of motion in metric perturbations in both space and time derivatives, including Horndeski and GLPV theories. We relate the EFT operators in ADM form to the four additional free functions of time in the scalar and tensor equations. Using the generalized slow roll formalism, we show that each power spectrum can be described by an integral over a single source that is a function of its respectivemore »« less
