Abstract. Light-by-Light scattering involves the interaction of two strong elec tromagnetic fields, resulting in the emission of two photons. In the next years, the ALICE 3 experiment is going to measure photons in the transverse mo mentum range pt = 1 - 50 MeV and 100 - 5000 MeV, which have not been investigated so far. Moving to a lower range of pt imposes a consideration of low-energy meson resonances which decay into two-photon channel. Further more, experimental possibilities to investigate the VDM-Regge mechanism are discussed. The role of the vertical background in light-by-light scattering mea surements is also shown.
