The conventional Skyrme interaction is generalized by adding zerorange
charge-symmetry-breaking and charge-independence-breaking terms,
and the corresponding energy density functional is derived. It is shown that
the extended model accounts for experimental values of mirror and triplet
displacement energies (MDEs and TDEs) in sd-shell isospin triplets with,
on average, ∼ 100 keV precision using only two additional adjustable coupling
constants. Moreover, the model is able to reproduce, for the first
time, the A = 4n versus A = 4n + 2 staggering of the TDEs.
