  Title Quark mixing in the discrete dark matter model Type Journal Article
  Year 2012 Publication Nuclear Physics B Abbreviated Journal Nucl. Phys. B  
  Volume 856 Issue 3 Pages 670-681  
  Keywords Discrete flavour symmetries; Dark matter; Meson oscillations  
  Abstract We consider a model in which dark matter is stable as it is charged under a Z(2) symmetry that is residual after an A(4) flavour symmetry is broken. We consider the possibility to generate the quark masses by charging the quarks appropriately under A(4). We find that it is possible to generate the CKM mixing matrix by an interplay of renormalisable and dimension-six operators. In this set-up, we predict the third neutrino mixing angle to be large and the dark matter relic density to be in the correct range. Low energy observables – in particular meson-antimeson oscillations – are hard to facilitate. We find that only in a situation where there is a strong cancellation between the Standard Model contribution and the contribution of the new Higgs fields, B meson oscillations are under control.
