Abstract

Kl3 decays constitute, at present, the golden modes to extract |Vus| from experimental data. Its incertitude is dominated by the theoretical error in the determination of the vector form factor at zero transfer of momentum. I review the most relevant analytical approaches for the calculation of this parameter.
