Vector-like quark interpretation for the CKM unitarity violation, excess in Higgs signal strength, and bottom quark forward-backward asymmetry

Abstract Due to a recent more precise evaluation of V ud and V us , the unitarity condition of the first row in the Cabibbo-Kobayashi-Maskawa (CKM) matrix: |V ud | 2 +|Vus| 2 +|V ub | 2 = 0.99798 ± 0.00038 now stands at a deviation more than 4σ from unity. Furthermore, a mild excess in the overall H...
