Abstract
AbstractWe present the first calculation of the scattering amplitude in the singlet channel beyond QCD. The calculation is performed in SU(2) gauge theory with $$N_f=2$$ N f = 2 fundamental Dirac fermions and based on a finite-volume scattering formalism. The theory exhibits a $$SU(4) \rightarrow Sp(4)$$ S U ( 4 ) → S p ( 4 ) chiral symmetry breaking pattern that is used to design minimal composite Higgs models currently tested at the LHC. Our results show that, for the range of underlying fermion mass considered, the lowest flavour singlet state is stable.
