An effective strongcoupling theory of composite particles in UVdomain
/ Xue, SheSheng
We briefly review the effective field theory of massive composite particles, their gauge couplings and characteristic energy scale in the UVdomain of UVstable fixed point of strong fourfermion coupling, then mainly focus the discussions on the decay channels of composite particles into the final states of the SM gauge bosons, leptons and quarks.
