Query: Towards realistic models of quark masses with geometrical CP violation   We present a model for quark masses and mixing, featuring geometrical CP
violation through a \Delta(27) triplet. By employing a single U(1)_F or Z_N
symmetry in addition to \Delta(27), we forbid all terms in the scalar potential
that would spoil the calculable phases the triple acquires. The quark sector is
realised by mimicking an existing scheme that reproduces the masses and CKM
mixing, with the extra symmetry enabling the hierarchies in the Yukawa
couplings through a Froggatt-Nielsen mechanism.
