The long-distance and non-local parts of the form factors describing the single-photon mediated $K_{S,L}\to\pi^0\gamma^*\to\pi^0\ell^+\ell^-$ ($\ell = e, \mu$) transitions in the standard model are addressed in QCD in the limit where the number $N_c$

I review kaon decays. I introduce the flavor problem and possible solutions. Very rare kaon decays like K→πνν¯ are very important to this purpose: we study also K→πl+l−,K→ππee where chiral dynamics is important to disentangle short dis

Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths and the availability of very large datasets. On the other hand, useful

The soft wall model in holographic QCD has Regge trajectories but wrong operator product expansion (OPE) for the two-point vectorial QCD Green function. We modify the dilaton potential to comply with the OPE. We study also the axial two-point functio

The LHC observed deviations from the Standard Model (SM) in the flavor sector: LHCb found a 4.3σ discrepancy compared to the SM in b → sμμ transitions and CMS reported a non-zero measurement of h → μτ with a significance of 2.4σ. Here we di
