Description
Scalar Diquarks which only couple to right-handed down-type quarks are difficult to resolve at colliders due to being able to hide amongst jet backgrounds. Using Standard Model Effective Field Theory we can also find indirect constraints on these diquarks from observables in flavour physics such as neutral meson oscillations and meson decays. Comparing current measurements from colliders and flavour physics we can show that while each test different regions in the diquark parameter space, both combined can rule out down-type diquarks below multi-TeV scales.
