Search for light custodians in a clean decay channel at the LHC

de Sandes, H., Rosenfeld, R.

Understand

Models of warped extra dimensions with custodial symmetry usually predict the existence of a light Kaluza-Klein fermion arising as a partner of the right-handed top quark, sometimes called light custodians which we will denote $\tilde{b}_R$.

  • The production of these particles at the LHC can give rise to multi-W events which could be observed in same-sign dilepton channels, but its mass reconstruction is challenging.
  • In this letter we study the possibility of finding a signal for the pair production of this new particle at the LHC focusing on a rarer, but cleaner decay mode of a light custodian into a $Z$ boson and a $b$-quark.
  • In this mode it would be possible to reconstruct the light custodian mass.
