The inclusive penguin decays , which can be measured with great precision at Belle II, will shed light on the so-called B-anomalies. The subleading resolved contributions represent one of the largest uncertainties of these inclusive decays. Presently radiative corrections are calculated within soft-collinear effective theory to reduce them significantly. Here a factorisation theorem for the resolved contributions is crucial and the new method of refactorisation plays an important role.
