Abstract

Based on the relation between weak CP phase and the other three mixing angles in Cabibbo-Kobayashi-Maskawa matrix postulated by us before, the ranges of rho and eta have been estimated by using the best known two KM matrix elements Vud and Vcd (or Vus). It is found that, the upper limit on eta is about 0.008 which is consistent with that estimated by Wolfenstein more than ten years ago but far small than the present popular estimation.
