Dark Matter with Light and Ultralight Stückelberg Axions
Claudio Corianò, Matteo Maria Maglio, Alessandro Tatullo +1
Scenarios with axion-like particles of variable masses, from the milli-eV range to ultralight, can be generated in a natural way in the context of effective field theory models wit…
Conformal Unification in a Quiver Theory and Gravitational Waves
Claudio Corianò, Paul H. Frampton, Alessandro Tatullo
The detection of a stochastic background of gravitational waves can reveal details about first-order phase transitions (FOPTs) at a time of of the early universe. We sp…
An Axion-Like Particle from an Seesaw with
Claudio Corianò, Paul H. Frampton, Alessandro Tatullo +1
We investigate the decoupling of heavy right handed neutrinos in the context of an SO(10) GUT model, where a remnant anomalous symmetry is . In this model the see-saw mec…
Exact Correlators from Conformal Ward Identities in Momentum Space and Perturbative Realizations
Claudio Corianò, Matteo Maria Maglio, Alessandro Tatullo +1
The general solution of the conformal Ward identities (CWI's) in momentum space, and their matching to perturbation theory, allows to uncover some specific characteristics of the b…
Dark Matter with Stuckelberg Axions
Claudio Coriano, Paul H. Frampton, Nikos Irges +1
We review a class of models which generalize the traditional Peccei-Quinn (PQ) axion solution by a Stückelberg pseudoscalar. Such axion models represent a significant variant with…
