@article{Choi2021CosmicBA, title={Cosmic birefringence and electroweak axion dark energy}, author={Gongjun Choi and Weikang Lin and Luca Visinelli and Tsutomu. T. Yanagida}, journal={Physical Review D}, year={2021} }

Taking the recently reported non-zero rotation angle of the cosmic microwave background (CMB) linear polarization β = 0.35±0.14 deg as the hint for a pseudo Nambu-Goldstone boson quintessence dark energy (DE), we study the electroweak (EW) axion quintessence DE model where the axion mass is generated by the EW instantons. We find that the observed value of β implies a non-trivial U(1) electromagnetic anomaly coefficient (cγ), once the current constraint on the DE equation of state is also taken…

Quintessence axion dark energy and a solution to the hubble tension

Abstract We present a model in which the question about a nature of the dark energy and the recently raised Hubble tension can be addressed at once. We consider the electroweak axion in the minimal…

CMB birefringence from ultralight-axion string networks

The polarization of Cosmic Microwave Background (CMB) photons is rotated as they pass through (ultralight-) axion string loops. Studying this birefringence can reveal valuable information about the…

Quintessence axion revisited in light of swampland conjectures

- PhysicsClassical and Quantum Gravity
- 2019

We point out that the swampland conjectures, forbidding the presence of global symmetries and (meta-)stable de Sitter vacua within quantum gravity, pick up a dynamical axion for the electroweak SU(2)…

We conjecture a general upper bound on the strength of gravity relative to gauge forces in quantum gravity. This implies, in particular, that in a four-dimensional theory with gravity and a U(1)…

This review is meant to provide a guide to the scientific themes that will underlie the activity of the group during the preparation of the Euclid mission and discusses five broad topics: dark energy and modified gravity, dark matter, initial conditions, basic assumptions and questions of methodology in the data analysis.

Proton decay in a class of supersymmetric grand unified models

Abstract Proton decay is studied in supersymmetric grand unified models. Supersymmetry combined with SU(3)×SU(2)×U(1) at low energies allow in general ΔB ≠ 0 operators of dimension five as well as…

Abstract It has been recently argued that quantum gravity effects strongly violate all non-gauge symmetries. This would suggest that all low energy discrete symmetries should be gauge symmetries,…
