Event details

I will present results on the non-perturbative dynamics of $SU(2)$ gauge theory with two fundamental Dirac flavours.  The theory provides a minimal template which has been used to design strongly coupled extensions of the Standard Model. It can for instance be used  to build a minimal UV complete realisation in terms of a new strong sector with fermionic matter of a pseudo Goldstone composite Higgs model.

After summarising the relevant lattice methods used in our simulations I will focus on the scalar and pseudoscalar sector on the theory which are relevant for searches of new exotic resonances at the LHC. I will then discuss the leading order contribution to the scattering amplitude of Goldstone bosons, which are constrained by WW scattering measurements and could thus provide insights on the electroweak symmetry breaking mechanism.
