Cornering the axion with CP-violating interactions

no code implementations8 Oct 2020 Ciaran A. J. O'Hare, Edoardo Vitagliano

Besides CP-preserving interactions, axions and axion-like particles may also have small CP-violating scalar Yukawa interactions with nucleons and electrons.

Testing Stochastic Gravitational Wave Signals from Primordial Black Holes with Optical Telescopes

no code implementations5 Oct 2020 Sunao Sugiyama, Volodymyr Takhistov, Edoardo Vitagliano, Alexander Kusenko, Misao Sasaki, Masahiro Takada

Primordial black holes (PBHs) can constitute the predominant fraction of dark matter (DM) if PBHs reside in the currently unconstrained "sublunar" mass range.

Axion helioscopes as solar magnetometers

1 code implementation18 Jun 2020 Ciaran A. J. O'Hare, Andrea Caputo, Alexander J. Millar, Edoardo Vitagliano

To do this we consider a previously neglected component of the solar axion flux at sub-keV energies arising from the conversion of longitudinal plasmons.

Grand Unified Neutrino Spectrum at Earth: Sources and Spectral Components

no code implementations25 Oct 2019 Edoardo Vitagliano, Irene Tamborra, Georg Raffelt

We briefly review the dominant neutrino fluxes at Earth from different sources and present the Grand Unified Neutrino Spectrum ranging from meV to PeV energies.

Distinguishing Dirac and Majorana neutrinos by their gravi-majoron decays

1 code implementation3 May 2019 Lena Funcke, Georg Raffelt, Edoardo Vitagliano

Neutrinos may acquire small Dirac or Majorana masses by new low-energy physics in terms of the chiral gravitational anomaly, as proposed by Dvali and Funcke (2016).

Tunable axion plasma haloscopes

no code implementations26 Apr 2019 Matthew Lawson, Alexander J. Millar, Matteo Pancaldi, Edoardo Vitagliano, Frank Wilczek

We propose a new strategy to search for dark matter axions using tunable cryogenic plasmas.
