The Large Hadron Collider (LHC) searches for New Physics motivated by questions such as the hierarchy problem of scales (HP). This issue arises from the severe difference between the electroweak (EW) and the SM ultra-violet (UV) scale. Radiative corrections to the Higgs mass show the theory’s sensitivity, and the light Higgs boson suggests either new physics at the TeV scale or fine-tuning the SM. However, recent data from the LHC has been putting stringent bounds on theories beyond the SM. The Little Hierarchy Problem (LHP) concerns the sensitivity to the existing energy gap between the EW scale and the LHC reach scale. Hidden sectors address the LHP. They can present light colorless top partner that alleviates bounds from the LHC. Particularly, Neutral Naturalness (NN) is a family of models containing an additional dark
