  Recent intensive theoretical and experimental studies shed light on possible
new physics beyond the standard model of particle physics, which can be probed
with sub-eV energy experiments. In the second run of the OSQAR photon
regeneration experiment, which looks for the conversion of photon to axion (or
Axion-Like Particle), two spare superconducting dipole magnets of the Large
Hadron Collider (LHC) have been used. In this paper we report on first results
obtained from a light beam propagating in vacuum within the 9 T field of two
LHC dipole magnets. No excess of events above the background was detected and
the two-photon couplings of possible new scalar and pseudo-scalar particles
could be constrained.
