Description
I will critically introduce, classify and discuss the
fundamental open issues related to either composite or
elementary extensions of the standard model. As for the
progress I will exhibit, among other things, the first proof
of existence of nonsupersymmetric and non-asymptotically
free 4D Gauge-Yukawa theories (structurally similar to the
standard model) which are UV finite thanks to the existence
of an exact interacting quantum UV fixed point in the gauge,
Yukawa and scalar self-couplings. The quantum moduli space
of the theory will also be precisely determined. Theories
with this behaviour have been searched for on the lattice
for the past several decades. Our results show the critical
ingredients that are needed to construct these new classes
of theories and offer a strategy for future lattice studies.
I will then comment on the wide phenomenological impact of
this discovery.
