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.

Semileptonic kaon decays and the precise determination of $V_{us}$
hep-ph 2025-02 unverdicted novelty 2.0 of 10

A hybrid chiral perturbation theory and lattice QCD treatment of radiative corrections to kaon semileptonic decays is claimed to reach 10^-4 precision, yielding V_us = 0.22308(39)(39)(3) and sharpening the Cabibbo ang...
