Understanding Yukawa Matrices and Particle Masses

[maani]

Hi, did I understand this correct: The Yukawa matrices are the couplings of the particles to the Higgs filed. They are in general not diagonal, but could be diagonalized by proper unitary matrices. The physical masses of the particles are the eigenvalues of that diagonal matrix .

yes exactly! And for the quark sector, we obtain the CKM matrix!
