Special colloquium: Application of light-cone sum rules (LCSRs) to D(s)->Pl+l- decays
0 D+ → π+ℓℓ decays are of much interest from the point of view of GIM cancellation and potential new [...] modes using U-spin symmetry. Finally, I present results for Cabibbo-favoured modes, Ds+ → π+ℓℓ and D0 → K0ℓℓ, which proceed via the same weak annihilation mechanism as a byproduct of our analysis. More …
