Query: Light by Light Scattering at High Energy: a Tool to Reveal New Particles   We point out a few remarkable properties of the $\gamma\gamma\to\gamma\gamma$
process at high energy. They should allow to search for effects of new
particles and interactions. We give illustrations with threshold effects due to
pairs of new charged particles (charginos, charged Higgses, sfermions),
resonance effects due to s-channel production of neutral scalars (standard or
supersymmetric Higgs particles, technipions) and unitarity saturating
amplitudes due to a strongly interacting sector. The use of polarized photon
beams is also briefly discussed.
