Description
While the presence of top partners below the TeV scale is predicted by naturalness, the search at ATLAS and CMS for these states has so far been unsuccessful. Focussing on supersymmetry, we show that a large mixing between the right-handed charm and top squarks
(i) is allowed by low-energy flavour constraints;
(ii) reduces the experimental bound on the stop mass;
(iii) has a mild, but bene?cial, eff?ect on ?ne-tuning;
(iv) leads to interesting signatures at the LHC
not presently investigated by experiments.
We estimate the current bound on the stop mass, in presence of flavour mixing, and discuss the new collider signatures.
