Abstract: We present a solution to the electroweak hierarchy problem, where the relevant new particles are third-generation philic and hidden in Standard Model processes with third-generation fermions. Due to this feature, the mass bounds from direct searches are much weaker, and the required fine-tuning can be reduced drastically. A concrete model is constructed based on a S U ( 6 ) / S p ( 6 ) fundamental composite Higgs model with collective symmetry breaking and an extended hypercolor mechanism. The construction allows us to raise the scale f to ∼ 3 TeV , corresponding to resonances at M ρ ≳ 10 TeV , without much tuning—employing ingredients that are naturally inherent in the (composite) Goldstone-Higgs framework. The experimental signatures are discussed in detail. It is found that current bounds allow for a model with negligible tuning. Published by the American Physical Society 2024
