New Theory Group Paper on Gravitational waves from axionic defects
April 20, 2022Theory Division
“High Quality QCD Axion at Gravitational Wave Observatories” by Ricardo Z. Ferreira, O. Pujolas and collaborators has been published at Physical Review Letters.
The paper shows that the domain walls formed in heavy QCD axion models can generate a stochastic background of gravitational waves within the reach of current and future gravitational wave detectors (e.g. LIGO-VIRGO-KAGRA, LISA). Remarkably, the signal can be disentangled from other sources due to the prediction of correlated signals at near-future neutron and proton electric dipole moments experiments.
