Tasting flavoured Majorana dark matter

A bstract We study a simplified model of flavoured Majorana dark matter in the Dark Minimal Flavour Violation framework. The extends Standard Model by flavour triplet and scalar mediator, through which new fermions couple to right-handed up-type quarks. This interaction is governed coupling matrix λ assumed constitute only source CP violation. analyse parameter space this using constraints from collider searches, D 0 − $$ \overline{D} D ¯ mixing, cosmology direct searches. Throughout our study, we point out crucial differences between Dirac cases. After performing combined analysis within context all experimental mentioned above, for particle preferred data. further investigate if capable explaining large measured value asymmetry \Delta {A}_{\mathrm{CP}}^{\mathrm{dir}} ∆ A CP dir charm decays. find that significant enhancements with respect expectation are compatible constraints, even central measurement can be reached. also advertise flavour-violating final state two same-sign top quarks produced association missing transverse energy as smoking-gun signature at LHC.
