Abstract

The standard model (SM) of particle physics encodes our current understanding of elementary particles. Despite having been tested by many experiments to a high level of accuracy, no significant deviations from SM predictions have been observed so far. With the start of the Large Hadron Collider (LHC) at CERN , particle physics entered a new era. The most sensational achievement of the LHC has been the detection of the Higgs boson. Although we may think that all pieces of the big jigsaw puzzle of nature have now been revealed, our modern understanding of quantum field theories tells us that the SM is necessarily incomplete and cannot be valid up to any large scales. Moreover, the SM does not answer a number of crucial questions about nature, such as neutrino masses and the nature of dark matter. In this talk I will show how the characterisation of the Higgs boson in terms of its coupling to the other particles in the SM is one of the key elements of the fascinating question for New Physics and gives us important clues about the fate of our Universe.
