Fundamental physics with high energy cosmic gamma rays The 2014 edition of the SciNeGHE workshop focuses on the interplay between very-high energy gamma astrophysics and fundamental physics. Observations of high Energy gamma rays are performed nowadays: from space, by the Large Area Telescope onboard the Fermi satellite and by the AGILE satellite, and from Earth, by the Imaging Air Cherenkov Telescopes H.E.S.S., MAGIC and VERITAS, and by the Extensive Air Shower detector HAWC (under completion). These instruments have discovered different populations of gamma-ray emitters and studied in detail the non-thermal processes producing this high-energy radiation. Their scientific objectives include also questions related to fundamental physics. Using gamma-ray instruments we study the origin of cosmic rays, and the cosmic electron-positron spectrum at high energies; moreover, we can search for signatures of dark matter. By observing the gamma-ray emission from sources at cosmological distances, we measure the intensity and evolution of the extragalactic background radiation, measure the energy of the cosmic vacuum searching for axion-like particles in a domain complementary to laboratory experiments, and perform tests of Lorentz invariance. This is why the field is in rapid development, and many new experiments involving experimental particle physicists are in construction and in project.
