Signature of pseudo Nambu–Goldstone Higgs boson in its decay
If the Higgs boson is a pseudo Nambu–Goldstone boson (PNGB), the hZγ contact interaction induced by the O(p4) invariants of the non-linear sigma model is free from its nonlinearity effects. The process h→Zγ can be used to eliminate the universal effects of heavy particles, which can fake the nonline...
