First off, what is a mass eigenstate?! Is there a (hermitian) operator associated to mass? What should I picture when discussing a non-mass-eigenstate?! The same goes for a 'weak eigenstate' as the CKM matrix is supposed to be the basis transformation between these two...
The I read that 'a linear transformation which diagonalizes the mass terms of the u-type quarks does not necessarily diagonalize those of the d-type quarks.'
What does this mean, and why not?!
Finally, I rwill be very much helped by any insight on the meaning of this matrix and its properties, e.g. why its unitary...?
Sorry, the more I learn the less I seem to know...
