At leading order, the theoretical interpretation of these measurements is straightforward. However, to reach high precision determinations of $\\phi_d$ and $\\phi_s$, which is essential in view of the searches for signs of beyond the SM physics, corrections from next-to-leading order effects need to be accounted for. These corrections primarily originate from so-called penguin topologies.
