The ratio of branching fractions for \(K^ - \to e^ - \bar \nu _e \pi ^0\) andK− → π−π0 decays has been measured using the ISTRA+ spectrometer. The result of our measurement is the following: $$\mathcal{R}_{Ke_3 /K_{2\pi } } = 0.2423 \pm 0.001

The rare decay KL0 → π0ν\( \tilde v \) branching ratio measurement is one of the clearest Standard Model test. Calculations based on the SM predict Br(KL0 → π0ν\( \tilde v \)) ≈ 2.8 × 10−11, but the most accurate experimental value Br(KL
