The unification of gauge and top Yukawa couplings is an attractive feature of gauge-Higgs unification models in extra-dimensions. This feature is usually considered difficult to obtain based on simple group theory analyses. We consider a minimal toy model including the renormalisation group running at one loop. The gauge couplings unify asymptotically at high energies, and we discuss presence...
Due to quark-gluon confinement in QCD, the quark masses entering the QCD Lagrangian cannot be measured directly like, for example, the electron or the proton mass. They must be determined either numerically from Lattice QCD, or analytically using QCD sum rules. The latter makes use of the complex squared energy plane, and Cauchy’s theorem for the current-current correlator of the axial-vector...
We will introduce a new paradigm that allows to define composite models that feature an interacting fixed point in the UV (asymptotic safety). This is based on large Nf resummation techniques. I will describe an example that features a composite Higgs and Dark Matter at low energies, and that allows to generate flavour physics dynamically via partial compositeness.
