Description
Composite Higgs models offer an elegant solution to the hierarchy problem by assuming that the Higgs boson is not an elementary particle but a composite state. The Higgs emerges as a pseudo-Nambu-Goldstone boson due to spontaneous symmetry breaking within a new strongly interacting sector.
We focus on minimal realizations of such models with fermionic UV completions that preserve custodial symmetry and naturally include fermionic resonances acting as top partners. These models predict spin-1 resonances which carry electroweak quantum numbers.
We find that three such states mix significantly with the electroweak gauge bosons, allowing their single production in Drell-Yan-like processes at the LHC. We explore the rich LHC phenomenology of these states and find scenarios where their masses could be as low as 1.5 TeV.
