These not only concern its theoretical applications, such as the a-theorem in four dimensions, but also phenomenological ones. In this talk I will review some of the potential manifestations of the dilaton in Nature: at the electroweak scale in relation to the recently discovered Higgs-like particle, and in cosmology owing to its connection with the energy of the vacuum. --------- Pour plus d'informations, merci de contacter Frigerio M. |
