New quark singlets T can be produced in pairs at LHC through standard QCD interactions, with a large cross section for masses of several hundreds of GeV. Their charged current decays T T̄ → W+bW−b̄, with semileptonic decay of the W pair, give a final state lνbb j j, as in top pair production. The mixed decay modes T T̄ → W+bHt̄,Ht W−b̄ → W+bW−b̄H, T T̄ → WbZt̄,Zt W−b̄ → W+bW−b̄Z, with H,Z → j j, yield tw...

Using the isospin analysis, the fact that penguin is pure ∆I = 1/2 transition, the unitarity for tree graph and C-invariance of strong interactions, it is shown that δ t = 0 = ˜ δ t
