ne pas payer une prostituée Light-by-light scattering, predicted in 1936, was observed for the first time by the ATLAS experiment at the LHC, thanks to "ultra-peripheral" collisions of lead ions. It is of particular interest to physicists, as it is the result of interactions between a vacuum and intense electromagnetic fields.
site rencontre gratuite badoo According to electromagnetic theory, the four-photon reaction γ+γ→γ+γ is impossible because two waves emitted by incoherent sources do not interfere. Yet extreme electromagnetic fields can act on a vacuum and "polarize" it. The vacuum can, in turn, induce non-linear effects on the fields… and make the impossible possible!
rencontre a xv presentateur The physicists in this study looked at collisions of 5 TeV lead ions at the LHC to find events in which lead ions merely graze. The ultra-relativistic charged particles produce an electromagnetic field with high gamma-ray intensity. Since, the frontal collision is avoided, the production of several hundred particles does not occur and the extreme fields associated with the ions can, therefore, interact (1025 V/m). The team was able to isolate 13 candidates for the light-by-light scattering among four billion physics events.

The scientists now have direct experimental evidence indicating that the QED vacuum differs from the classical vacuum, whereas all previous evidence of this was indirect, albeit of very high quality (Lamb and Dehmelt/Paul Nobel Prizes).

CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
