摘要 We propose a new mass matrix ansatz： At the grand unified （GU） scale, the standard model （SM） Yukawa coupling matrix elements are integer powers, of the square root of the GU gauge coupling constant ε ≡√αGU, multiplied by order unity random complex numbers. It relates the hierarchy of the SM fermion masses and quark mixings to the gauge coupling constants, greatly reducing the SM parameters, and can give good fitting results of the SM fermion mass, quark mixing and CP violation parameters. This is a neat but very effective ansatz.
