We show that the standard model Higgs field can realize the quadratic chaotic inflation, if the kinetic term is significantly modified at large field values. This is a simple realization of the so-called running kinetic inflation. The point is that the Higgs field respects an approximate shift symmetry at high energy scale. The tensor-to-scalar ratio is predicted to be $r \simeq 0.13 - 0.16$, which nicely explains the primordial B-mode polarization, $r=0.20^{+0.07}_{-0.05}$, recently discovered by the BICEP2 experiment. In particular, allowing small modulations induced by the shift symmetry breaking, the negative running spectral index can also be induced. The reheating temperature is expected to be so high that successful thermal leptogenesis is possible. The suppressed quartic coupling of the Higgs field at high energy scales may be related to the Higgs chaotic inflation.

The paper

Original abstract

We show that the standard model Higgs field can realize the quadratic chaotic inflation, if the kinetic term is significantly modified at large field values. This is a simple realization of the so-called running kinetic inflation. The point is that the Higgs field respects an approximate shift symmetry at high energy scale. The tensor-to-scalar ratio is predicted to be $r \simeq 0.13 - 0.16$, which nicely explains the primordial B-mode polarization, $r=0.20^{+0.07}_{-0.05}$, recently discovered by the BICEP2 experiment. In particular, allowing small modulations induced by the shift symmetry breaking, the negative running spectral index can also be induced. The reheating temperature is expected to be so high that successful thermal leptogenesis is possible. The suppressed quartic coupling of the Higgs field at high energy scales may be related to the Higgs chaotic inflation.

Higgs inflation at the critical point
hep-ph 2014-03 conditional novelty 6.0 of 10

Near the Higgs inflation critical point the effective potential develops a feature that can raise the tensor-to-scalar ratio from 0.003 to 0.1 or more, tying it to the top quark and Higgs masses.
Higgs inflation from Standard Model criticality
hep-ph 2014-08 conditional novelty 5.0 of 10

A Higgs-inflation model built on the near-criticality of the Standard Model potential can reproduce the observed spectral index, its running, and a tensor-to-scalar ratio up to 0.2, provided the top mass is tuned and ...
Blue Tensor Spectrum from Particle Production during Inflation
astro-ph.CO 2014-05 conditional novelty 5.0 of 10

Gauge quanta produced by a rolling axion during inflation can source a blue gravitational-wave spectrum, reconciling BICEP2 and Planck, and the axion potential is in principle reconstructable from that spectrum.
Higgs inflation still alive
hep-ph 2014-03 conditional novelty 5.0 of 10

Tuning the Higgs quartic coupling to near-criticality at 10^17 GeV lets Higgs inflation work with a non-minimal coupling below ten, yielding a tensor-to-scalar ratio near 0.2.
Solving the Tension between High-Scale Inflation and Axion Isocurvature Perturbations
hep-ph 2014-03 conditional novelty 5.0 of 10

Breaking the Peccei-Quinn symmetry to a discrete subgroup during inflation gives the axion a mass of order the Hubble scale, suppressing the isocurvature perturbations that otherwise conflict with high-scale inflation.

Cosmological constraints on neutrinos after BICEP2
astro-ph.CO 2014-04 conditional novelty 4.0 of 10

Combining Planck, BICEP2, and local astrophysical data, the authors report a ~4-sigma preference for nonzero neutrino mass and a ~0.5 eV sterile neutrino, and argue these models relieve the Planck-BICEP2 tensor-to-sca...
Multi-Natural Inflation in Supergravity and BICEP2
hep-ph 2014-03 conditional novelty 4.0 of 10

A two-sine-wave inflaton potential can span a broad region of (n_s, r) space, including n_s near or above unity with r around 0.1 to 0.2, so the model is not excluded by BICEP2.
