# Parity Violating Non-Gaussianity from Axion-Gauge Field Dynamics

@inproceedings{Ozsoy2021ParityVN, title={Parity Violating Non-Gaussianity from Axion-Gauge Field Dynamics}, author={Ogan Ozsoy}, year={2021} }

We study scalar-tensor-tensor and tensor-scalar-scalar three point cross correlations generated by the dynamics of a transiently rolling spectator axion-U(1) gauge field model during inflation. In this framework, tensor and scalar fluctuations are sourced by gauge fields at the non-linear level due to gravitational interactions, providing a chiral background of gravitational waves while keeping the level of scalar fluctuations at the observationally viable levels at CMB scales. We show that the… Expand

In string theory inspired models of axion-like fields, sub-leading non-perturbative effects, if sufficiently large, can introduce steep cliffs and gentle plateaus onto the underlying scalar… Expand

We calculate the bispectrum of scale-invariant tensor modes sourced by spectator SU(2) gauge fields during inflation in a model containing a scalar inflaton, a pseudoscalar axion and SU(2) gauge… Expand

Observable non-gaussianity from gauge field production in slow roll inflation, and a challenging connection with magnetogenesis

In any realistic particle physics model of inflation, the inflaton can be expected to couple to other fields. We consider a model with a dilaton-like coupling between a U(1) gauge field and a scalar… Expand

When inflation is driven by a pseudoscalar field χ coupled to vectors as α4χFF˜, this coupling may lead to a copious production of gauge quanta, which in turns induces non-Gaussian and… Expand
