Gauge Mediation of Exact Scale Breaking
Alberto Mariotti (Durham)

I will first review basic aspects of extensions of the Standard Model where UV scale invariance aim to protect the Higgs mass from quantum corrections.
I will then present a gauge mediation principle for BSM theories where exact UV scale invariance is broken in a hidden sector:
the relevant configurations are those in which the Standard Model and a hidden sector emanate from a scale invariant pair of UV theories that communicate only via gauge interactions. I will show that in such configurations, once scale invariance is broken in the hidden sector, relevant operators are generated in the Higgs potential, leading to electroweak symmetry breaking.
The resulting Higgs potential differs from the Standard Model and contains logarithmic mass-squared terms which can lead to unusual Higgs self-couplings.
