Yukawa Bound States and Their LHC Phenomenology

Abstract EN

We present the current status on the possible bound states of extra generation quarks.

These include phenomenology and search strategy at the LHC.

If chiral fourth-generation quarks do exist their strong Yukawa couplings, implied by current experimental lower bound on their masses, may lead to formation of bound states.

Due to nearly degenerate 4G masses suggested by Precision Electroweak Test one can employ “heavy isospin” symmetry to classify possible spectrum.

Among these states, the color-octet isosinglet vector ω8 is the easiest to be produced at the LHC.

The discovery potential and corresponding decay channels are covered in this paper.

With possible light Higgs at ~125 GeV two-Higgs doublet version is briefly discussed.
