High Quality QCD Axion at Gravitational Wave Observatories
Ricardo Z. Ferreira, Alessio Notari, Oriol Pujolàs +1
The axion solution to the strong CP problem is delicately sensitive to Peccei-Quinn breaking contributions that are misaligned with respect to QCD instantons. Heavy QCD axion model…
Dark Sector to Restore Cosmological Concordance
Itamar J. Allali, Mark P. Hertzberg, Fabrizio Rompineve
We develop a new phenomenological model that addresses current tensions between observations of the early and late Universe. Our scenario features: (i) a decaying dark energy fluid…
Recipes for Oscillon Longevity
Jan Olle, Oriol Pujolas, Fabrizio Rompineve
Oscillons are localized states of scalar fields sustained by self interactions. They decay by emitting classical radiation, but their lifetimes are surprisingly large. We revisit t…
