Revisiting longitudinal plasmon-axion conversion in external magnetic fields
Andrea Caputo, Alexander J. Millar, Edoardo Vitagliano
In the presence of an external magnetic field the axion and the photon mix. In particular, the dispersion relation of a longitudinal plasmon always crosses the dispersion relation…
Scalar Direct Detection: In-Medium Effects
Graciela B. Gelmini, Volodymyr Takhistov, Edoardo Vitagliano
A simple extension of the Standard Model consists of a scalar field that can potentially constitute the dark matter (DM). Significant attention has been devoted to probing light $\…
Axion helioscopes as solar magnetometers
Ciaran A. J. O'Hare, Andrea Caputo, Alexander J. Millar +1
Axion helioscopes search for solar axions and axion-like particles via inverse Primakoff conversion in strong laboratory magnets pointed at the Sun. Anticipating the detection of s…
Probing dark photons with plasma haloscopes
Graciela B. Gelmini, Alexander J. Millar, Volodymyr Takhistov +1
Dark photons (DPs) produced in the early Universe are well-motivated dark matter (DM) candidates. We show that the recently proposed tunable plasma haloscopes are particularly adva…
Distinguishing Dirac and Majorana neutrinos by their gravi-majoron decays
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). This model pred…
Tunable axion plasma haloscopes
Matthew Lawson, Alexander J. Millar, Matteo Pancaldi +2
We propose a new strategy to search for dark matter axions using tunable cryogenic plasmas. Unlike current experiments, which repair the mismatch between axion and photon masses by…
