Quark contact interactions at the LHC
F. Bazzocchi, U. De Sanctis, M. Fabbrichesi +1
Quark contact interactions are an important signal of new physics. We introduce a model in which the presence of a symmetry protects these new interactions from giving large correc…
Fermions and Goldstone bosons in an asymptotically safe model
F. Bazzocchi, M. Fabbrichesi, R. Percacci +2
We consider a model in which Goldstone bosons, described by a SU(N) chiral nonlinear sigma model, are coupled to an N-plet of colored fermions by means of a Yukawa interaction. We…
Telling the spin of the "Higgs boson" at the LHC
U. De Sanctis, M. Fabbrichesi, A. Tonero
We assume that the Higgs boson or a possible resonance---playing its role in strongly interacting models of electroweak symmetry breaking---has been discovered at the LHC and propo…
The electroweak S and T parameters from a fixed point condition
M. Fabbrichesi, R. Percacci, A. Tonero +1
We consider the standard model without the Higgs boson, where the Goldstone modes are described by a nonlinear sigma model. We study the renormalization group flow of the sigma mod…
