Description
We consider a flavour framework in which quark mass hierarchies naturally arise from a small departure of the modulus VEV from special stabilised regions of genus 2. By extending the modular group to this genus, the same VEV can also account for the spontaneous breaking of the assumed CP symmetry. We present a modular quark model which is able to fit both the mass hierarchies and the CKM matrix through a single mechanism, where the quark mass ratios vanish in the residual symmetry (and CP conserving) limit.
