Description
The semileptonic decays $K^+ \to \pi^0 \ell^+ \nu(\gamma)$ provide a clean way to test the $e$-$\mu$ lepton universality and probe the first-row unitarity $|V_{ud}|^2 + |V_{us}|^2 + |V_{ub}|^2 = 1$ of the CKM matrix. This work aims to update the branching fractions of semileptonic kaon decays, along with the other main kaon decay channels, by one-track analysis using a minimum-bias low-intensity dataset collected by the NA62 experiment at CERN. The current status of the analysis will be presented.
