DESCRIPTION:If a horizontal U(1) symmetry H is responsible for the generat
 ion of the standard model (SM) mass hierarchies\, cancellation of the mixe
 d SM-H anomalies (in the supersymmetric case) results in a set of striking
  prediction: the up quark is massless\, providing a simple solution to the
  strong CP problem\, and the $\\mu$ term is necessarily somewhat below the
  SUSY scale\, thus solving in a natural way the SUSY $\\mu$ problem. Contr
 ary to common belief\, we show that phenomenologically viable models can b
 e constructed without appealing to the Green-Schwartz anomaly cancellation
  mechanism. Few remarks on the naturalness of light sterile neutrinos in t
 his same framework will be discussed as well.\n\nhttps://indico.ific.uv.es
