Data-driven extraction of amplitudes in D to pi pi decays reveals a penguin term 4.74 times larger than the tree amplitude, inconsistent with SM estimates at >3.3 sigma and requiring new physics.
In our analysis we have ignored electroweak penguins (pEW ) which is justifiable within SM, but they can be sizable in the presence of NP
