“…If the stimulating beam is diraction and Fourier limited, and if its optics and pulse length are adapted to the two other colliding beams, F is simply equal to the number of photons in the stimulating beam. For m a = 1eV, g = 1 0 10 GeV -1 , F = 1 0 16 , w e get = 1 0 9 s. Clearly the axion does not decay inside the detector.…”

An experimental program is in progress, searching for possible non QED signals in elastic photon-photon scattering in the optical domain [1]. We examine here the potential of this process for the detection of a possible light pseudoscalar such a s the axion. A IntroductionThe standard model currently provides a consistent description of elementary particles and of their interactions. Yet, it contains spontaneously broken global symmetries which imply the existence of Goldstone bosons. In the case of the U(1) Peccei-Quinn symmetry introduced to explain the absence of CP violation in QCD [2], this particle is called the axion. These particles have escaped detection up to now.Originally, the mass scale of the U P Q (1) symmetry breaking was thought t o b e t h e same as the one for weak interactions, which implies an axion mass m a 100keV. This type of axion has been ruled out by particle decay and beam dump experiments. Pseudoscalar or scalar particles that couple to two photons but not to fermions have also been considered in ref. [6]. In that case, m a and g are two independent parameters.The actual window for the invisible axion is mainly limited by astrophysical considerations (see the reviews in [7]). Axions can be produced in the core of stars via the Primako 1

“…Therefore the contribution of the axion never dominates (g. 4). The soft dependance of the axion cross section and of the QED cross section [16] on polarisation and on angle does not provide any help. …”
