We provide a non-linear realisation of Composite Higgs Model in the context of SU(4)xSU(4)/Sp(4) symmetry breaking pattern, where the effective Lagrangian of the spin-0 and spin-1 resonances in this model is constructed via the CCWZ prescription.


This model is for Madgraph, where spin-0 and spin-1 resonances are implemented into an SU(4)/Sp(4) composite Higgs model using the Hidden symmetry technology. There are 15 vectors and axial-vectors, plus 4 SM gauge bosons, which give rise to 4 x 4 and 5 x 5 mixing structures for the charged and neutral gauge sectors respectively. The Feynrule model file is provided. One python code is implemented as the model parameter calculator. More detail descriptions for the Lagrangian can be found in arXiv: 1605.01363.
