Using a large sample of pure, slow, short lived K0 mesons collected with KLOE detector at DaFne, we have measured the KS lifetime. From a fit to the proper time distribution we find tau = (89.562 +- 0.029_stat +- 0.043_syst) ps. This is the most precise measurement today in good agreement with the world average derived from previous measurements. We observe no dependence of the lifetime on the direction of the Ks.

Nelson-Barr mechanism yields ultralight scalar dark matter inducing time-periodic variation in CKM matrix elements, distinguishable from QCD axion and detectable via nuclear clocks.
