The chromomagnetic operator on the lattice
We study matrix elements of the "chromomagnetic" operator on the lattice.This operator is contained in the strangeness-changing effective Hamiltonian which describes electroweak effects in the Standard Model and beyond.Having dimension 5, the chromomagnetic operator is characterized by a rich pattern of mixing with other operators of equal and lower dimensionality, …
