“…Remarkably, the hinted value for g aγ is roughly the same of what required for the ALP explanation of the observed transparency hints -the latter requiring however m a 10 −7 eV -and is in full reach of the next generation ALP detectors [48][49][50][51].…”

“…More recently, it was also pointed out that anomalous X-ray observations of the active Sun suggest an ALP-photon coupling of the same size hinted by the other analyses [74]. Interestingly, the required couplings are not excluded by experiments nor by phenomenological considerations and are accessible to the new generation ALP detectors, in particular ALPS II [48] and the International Axion Observatory (IAXO) [49][50][51].…”

Several stellar systems (white dwarfs, red giants, horizontal branch stars and possibly the neutron star in the supernova remnant Cassiopeia A) show a mild preference for a non-standard cooling mechanism when compared with theoretical models. This exotic cooling could be provided by Weakly Interacting Slim Particles (WISPs), produced in the hot cores and abandoning the star unimpeded, contributing directly to the energy loss. Taken individually, these excesses do not show a strong statistical weight. However, if one mechanism could consistently explain several of them, the hint could be significant. We analyze the hints in terms of neutrino anomalous magnetic moments, minicharged particles, hidden photons and axion-like particles (ALPs). Among them, the ALP or a massless HP represent the best solution. Interestingly, the hinted ALP parameter space is accessible to the next generation proposed ALP searches, such as ALPS II and IAXO and the massless HP requires a multi TeV energy scale of new physics that might be accessible at the LHC. arXiv:1512.08108v2 [astro-ph.HE]

“…From the Mathiessen rule, the total decay rate is Γ ¼ Γ φ→γγ þ Γ φ→pl ≃ Γ φ→pl , which is valid since we are here discarding higher-order processes such three-wave mixing (nonlinear decay), possibly occurring in extremely dense media or in the presence of shock waves [51]. In a typical discharge plasma, n 0 ∼ 10 10 cm −3 , with a magnetic field of B 0 ∼ 1 T, strong coupling can be achieved in a region of parameters that has not yet been excluded by the experiments [52,53].

Axions are hypothetical particles related to the violation of the charge-parity symmetry within the strong sector of the standard model, being one of the most prone candidates for dark matter. Multiple attempts to prove their existence are currently performed in different physical systems. Here, we predict that axions may couple to the electrostatic (Langmuir) modes of a strongly magnetized plasma, and show that a new quasiparticle can be defined, the axion-plasmon polariton. The excitation of axions can be inferred from the pronounced modification of the dispersion relation of the Langmuir waves, a feature that we estimate to be accessible in state-of-the-art plasma-based experiments.

“…Though with much smaller effective area, they have significantly higher energy resolution, thus may also be able to help us better understand the ALP properties. Together with the upcoming ALP-II [57] and IAXO [58] experiments, significant progresses on revealing the ALP properties are expected in the next decade.…”

Axion-like particles (ALPs) can oscillate to photons and vice versa in electromagnetic fields. The photon-ALP oscillation provides an attractive solution to the apparent transparency of the Universe to TeV photons. The allowed parameter regions for the ALP mass m a ≤ 10 −7 eV have been tightly constrained by the Fermi-LAT and H.E.S.S observations of some extragalactic sources. In this work we show for the first time that the H.E.S.S observations of some TeV sources in the Galactic plane exclude the highest ALP mass region (i.e., m a ∼ a few × 10 −7 eV) that accounts for the TeV transparency of the Universe. The upcoming CTA observations of the Galactic TeV sources are shown to be able to improve the constraints significantly. PACS numbers: 95.35.+d, 95.85.Pw
