“…1000 µeV with E/C = 8/3. Especially for m a = 6.7 µeV, this equation predicts g aγγ 8.1 × 10 −16 GeV −1 for models with E/C = 8/3 like the Dine-Fischler-Srednicki-Zhitnitsky (DFSZ) model [28], which is still in the allowed region by the recent axion dark matter search, with m a around 6.7 µeV [84].…”

At low energies, the strong interaction is governed by the Goldstone bosons associated with the spontaneous chiral symmetry breaking, which can be systematically described by chiral perturbation theory. In this paper, we apply this theory to study the θ-vacuum energy density and hence the QCD axion potential up to next-to-leading order with N non-degenerate quark masses. By setting N = 3, we then derive the axion mass, self-coupling, topological susceptibility and the normalized fourth cumulant both analytically and numerically, taking the strong isospin breaking effects into account. In addition, the model-independent part of the axion-photon coupling, which is important for axion search experiments, is also extracted from the chiral Lagrangian supplemented with the anomalous terms up to O(p 6).

“…The constraints from astrophysical searches are shown by transparent shadings, including horizontal branch (HB) stars [41] in red, PKS 2155-304 by HESS [42] in magenta, NGC 1275 by Fermi [43] in orange, SN1987A [44] in green, and Chandra's observation of Hydra A [45], M87 [46], and NGC 1275 [47] in pink. The prospects for future proposed and planned experiments are shown individually by the red dashed curves for BabyIAXO and IAXO [48], black dashed curve for ALPS-II [49], blue dot-dashed lines for ABRA-CADABRA [32][33][34] with a broadband search, blue dashed lines for DM Radio-50L and DM Radio-m 3 [50][51][52], which has merged with ABRACADABRA, for a resonant search, 2 cyan dashed lines for CULTASK [53,54], magenta lines for MADMAX [55], orange dashed JHEP01(2021)172…”

Adding an axion-like particle (ALP) to the Standard Model, with a field velocity in the early universe, simultaneously explains the observed baryon and dark matter densities. This requires one or more couplings between the ALP and photons, nucleons, and/or electrons that are predicted as functions of the ALP mass. These predictions arise because the ratio of dark matter to baryon densities is independent of the ALP field velocity, allowing a correlation between the ALP mass, ma, and decay constant, fa. The predicted couplings are orders of magnitude larger than those for the QCD axion and for dark matter from the conventional ALP misalignment mechanism. As a result, this scheme, ALP cogenesis, is within reach of future experimental ALP searches from the lab and stellar objects, and for dark matter.

“…Experimental searches for axions via their photon coupling fall broadly into three categories: light-shiningthrough-wall experiments, which search for axions converting to and from photons either side of an opaque barrier [11][12][13][14][15]; haloscopes, which search for the cold population of axions that could constitute the dark matter halo of the Milky Way [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]; and helioscopes, the subject of this work, which search for the thermal flux of axions expected to be emitted by the Sun [33][34][35][36][37][38][39][40][41][42].

Axion helioscopes as solar magnetometers

et al. 2020

Axion helioscopes search for solar axions and axionlike particles via inverse Primakoff conversion in strong laboratory magnets pointed at the Sun. Anticipating the detection of solar axions, we determine the potential for the planned next-generation helioscope, the International Axion Observatory (IAXO), to measure or constrain the solar magnetic field. 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. This flux is sensitively dependent to the magnetic field profile of the Sun, with lower energies corresponding to axions converting into photons at larger solar radii. If the detector technology eventually installed in IAXO has an energy resolution better than 200 eV, then solar axions could become an even more powerful messenger than neutrinos of the magnetic field in the core of the Sun. For energy resolutions better than 10 eV, IAXO could access the inner 70% of the Sun and begin to constrain the field at the tachocline: the boundary between the radiative and convective zones. The longitudinal plasmon flux from a toroidal magnetic field also has an additional 2% geometric modulation effect which could be used to measure the angular dependence of the magnetic field.
