Description

Precise unambiguous predictions of CP-violating observables in charm decays are hard and often plagued by non-perturbative uncertainties. We calculate hadronic matrix elements with penguin topology in the weak nonleptonic D -> pi^+\pi^- and D -> K^+K^- decays using techniques of light-cone QCD sum rules. With that, we perform numerical analysis and estimate the direct CP-asymmetry in D -> pi^+\pi^- and D -> K^+K^- decays.
