Application of $K \to 3 π$ amplitudes to semileptonic kaon decays

Anshika Bansal, Jack Jenkins, Daniel Winney

We study dispersive representations of nonlocal form factors in $K^{+} \to π^{+} ℓ^{+} ℓ^{-}$ and $K^{+} \to π^{+} ν ν ˉ$ decays, with an aim of improving the theoretical description of…

$D \to P ℓ^{+} ℓ^{-}$ decays assisted by QCD light-cone sum rules

Anshika Bansal, Alexander Khodjamirian, Thomas Mannel

We suggest a new method to analyse the rare $D_{(s)} \to P ℓ^{+} ℓ^{-}$ decays ( $P = π, K$ ), combining QCD light-cone sum rules (LCSR) with hadronic dispersion relations. As our main…
