The Non-triviality of Dynamical Chern-Simons Gravity and the Standard Model
Stephon Alexander, Heliudson Bernardo, Cyril Creque-Sarbinowski
Given the growing interest in gravitational-wave and cosmological parity-violating effects in dynamical Chern-Simons (dCS) gravity, it is crucial to investigate whether the scalar-…
Higgs Inflation and the Electroweak Gauge Sector
Stephon Alexander, Cyril Creque-Sarbinowski, Humberto Gilmer +1
We introduce a new method that allows for the Higgs to be the inflaton. That is, we let the Higgs be a pseudo-Nambu-Goldstone (pNG) boson of a global coset symmetry that spon…
Magnetic Fields from Compensated Isocurvature Perturbations
Jordan Flitter, Cyril Creque-Sarbinowski, Marc Kamionkowski +1
Compensated isocurvature perturbations (CIPs) are perturbations to the primordial baryon density that are accompanied by dark-matter-density perturbations so that the total matter…
Parity-Violating Trispectrum from Chern-Simons Gravity
Cyril Creque-Sarbinowski, Stephon Alexander, Marc Kamionkowski +1
We show that dynamical Chern-Simons (dCS) gravity imprints a parity-violating signal in primordial scalar perturbations. Specifically, we find that, after dCS amplifies one gravito…
Compact Binary Foreground Subtraction in Next-Generation Ground-Based Observatories
Bei Zhou, Luca Reali, Emanuele Berti +4
The stochastic gravitational-wave backgrounds (SGWBs) for current detectors are dominated by binary black-hole (BBH) and binary neutron-star (BNS) coalescences. The sensitivity of…
Chern-Simons Gravity and Neutrino Self-Interactions
Stephon Alexander, Cyril Creque-Sarbinowski
Dynamical Chern-Simons gravity (dCS) is a four-dimensional parity-violating extension of general relativity. Current models predict the effect of this extension to be negligible du…
