ICHEP2012 Physics Highlights
Riccardo Barbieri
I describe some of the highlights of ICHEP2012 with an eye to the current status of particle physics.
A 125 GeV composite Higgs boson versus flavour and electroweak precision tests
Riccardo Barbieri, Dario Buttazzo, Filippo Sala +2
A composite Higgs boson of 125 GeV mass, only mildly fine-tuned, requires top partners with a semi-perturbative coupling and a mass not greater than about a TeV. We analyze the str…
Less Minimal Flavour Violation
Riccardo Barbieri, Dario Buttazzo, Filippo Sala +1
We consider the approximate U(2)^3 flavour symmetry exhibited by the quark sector of the Standard Model and all its possible breaking terms appearing in the quark Yukawa couplings.…
Flavour physics from an approximate U(2)^3 symmetry
Riccardo Barbieri, Dario Buttazzo, Filippo Sala +1
The quark sector of the Standard Model exhibits an approximate U(2)^3 flavour symmetry. This symmetry, broken in specific directions dictated by minimality, can explain the success…
