Prospects of searching for composite resonances at the LHC and beyond

Understand

Composite Higgs models predict the existence of resonances.

• We study in detail the collider phenomenology of both the vector and fermionic resonances, including the possibility of both of them being light and within the reach of the LHC.
• We present current constraints from di-boson, di-lepton resonance searches and top partner pair searches on a set of simplified benchmark models based on the minimal coset $SO(5)/SO(4)$, and make projections for the reach of the HL-LHC.
• We find that the cascade decay channels for the vector resonances into top partners, or vice versa, can play an important role in the phenomenology of the models.
