The Search for Variations of Fundamental Couplings and Mass Scales

The last decade has seen a dramatic improvement in the quality of tests of variations of fundamental couplings and mass scales in space and time. Currently, a large number of the astrophysical, cosmological, space-based and laboratory-based tests are being conducted. Should any of such tests give a non-zero result, they would also suggest a dynamical nature for the dark energy in the Universe, which makes them highly relevant for the on-going effort in cosmology to measure the dynamical properties of dark energy. The workshop aims to bring together atomic and nuclear physics experimentalists and theorists working on the implementation of such tests, and theoretical particle physicists and cosmologists working on creating consistent models that can account for changing couplings.
