Composite Higgs theories with partial compositeness are gauge theories, where the Higgs boson arises as a pseudo-Nambu-Goldstone boson (pNGB) and top-partners appear as bound states of three hyperfermions coming from a UV completion. These models offer a promising solution to the Higgs sector’s Naturalness problem and predict extra pNGBs and spin-1 resonances. Our focus is on the electroweak spin-1 resonances. We find that three of those states have an important mixing with the SM gauge bosons, allowing their single production in Drell-Yan like processes at LHC. We explore the rich LHC phenomenology of these states and find scenarios where their masses could be as low as 1.5 TeV.
