“…Also the beam ellipticity has been determined on the basis of a previous experiment [7]. Assuming that the effect is indeed due to a LPB, the corresponding physical parameters turn out to lie in the range 1.0 · 10 −3 eV ≤ m ≤ 1.5 · 10 −3 eV and 2 · 10 5 GeV ≤ M ≤ 6 · 10 5 GeV.…”

Light Pseudoscalar Bosons (LPBs) coupled to two photons are predicted by many realistic extensions of the Standard Model and give rise to birefringence and dichroism in a light beam travelling in an external magnetic field. These effects have recently been detected by the PVLAS collaboration, thereby strongly suggesting the existence of a LPB. We provide an astrophysical cross-check for such a claim. Actually, we show that in the double pulsar J0737-3039 photon-LPB conversion can give rise to a characteristic attenuation pattern of the light beam emitted by one of the pulsars when it goes through the magnetosphere of the companion. The effect under consideration shows up in the γ-ray band and can be detected by the upcoming GLAST mission.

“…In the last decades, high reflectivity interferential mirrors have been widely used in optical cavities to measure small light polarization variations induced by the propagation in a weakly anisotropic medium such as in parity violation experiments [1,2] or in vacuum magnetic birefringence experiments [3,4,5]. Mirrors themselves are birefringent and this is manifestly a problem for such a kind of applications because they induce a phase retardation [6] which superimposes to the signal to be measured.…”

In this paper we present a review of the existing data on interferential mirror birefringence. We also report new measurements of two sets of mirrors that confirm that mirror phase retardation per reflection decreases when mirror reflectivity increases. We finally developed a computational code to calculate the expected phase retardation per reflection as a function of the total number of layers constituting the mirror. Different cases have been studied and we have compared computational results with the trend of the experimental data. Our study indicates that the origin of the mirror intrinsic birefringence can be ascribed to the reflecting layers close to the substrate.

“…They used two superconducting dipole magnets of length L = 4.4 m which were able to provide a magnetic field of B = 3.7 T. The optical laser with a wavelength of λ = 514 nm had an average power of P = 3 W and was operated in an optical cavity providing 200 reflections. Since no signal from photon regeneration was found, the BFRT collaboration was able to set an upper limit on g aγγ of (35) g aγγ < 6.7 × 10 −7 GeV (95% C.L.) , …”

“…The maximum of ellipticity, a laser beam with a wavelength λ = 1550 nm propagating in a 9.5 T field over a length N L = 25 km would acquire is equal to 2 × 10 −11 rad. A search for both effects, birefringence and dichroism, was carried out with the same magnets used in the BFRT experiment (35), setting a bound on the axion to photon coupling constant of g aγγ < 3.6 × 10 −7 GeV −1 ,…”

“…3.2 represents the exclusion region in the m a vs. the inverse coupling constant M a plane, given for one day of operation (20 magnet pulses) and assuming a zero ellipticity measurement, based on the experimental parameters given above. The red curves indicate the Brookhaven (BFRT) result (35), the blue line the BMV projected result, and finally the black cross the region of values that could explain the PVLAS results. This interpretation would thus be excluded by a zero ellipticity measurement with the BMV setup.…”

Summary. Theoretical axion models state that axions are very weakly interacting particles. In order to experimentally detect them, the use of colorful and inspired techniques becomes mandatory. There is a wide variety of experimental approaches that were developed during the last 30 years, most of them make use of the Primakoff effect, by which axions convert into photons in the presence of an electromagnetic field. We review the experimental techniques used to search for axions and will give an outlook on experiments planned for the near future.
