This operator is contained in the strangeness-changing effective Hamiltonian which describes electroweak effects in the Standard Model and beyond.\n  Having dimension 5, the chromomagnetic operator is characterized by a rich pattern of mixing with other operators of equal and lower dimensionality, including also non gauge invariant quantities; it is thus quite a challenge to extract from lattice simulations a clear signal for the hadronic matrix elements of this operator.\n  We compute all relevant mixing coefficients to o","authors_text":"D.
