Decays of the heavy top and new insights on $$\epsilon _K$$ ϵ K in a one-VLQ minimal solution to the CKM unitarity problem
Abstract We propose a minimal extension of the Standard Model where an up-type vector-like quark, denoted T, is introduced and provides a simple solution to the CKM unitarity problem. We adopt the Botella-Chau parametrization in order to extract the $$4\times 3$$ 4 × 3 quark mixing matrix which cont...
