We present a global analysis of leptonic and semileptonic kaon decay data, including all recent results published by the BNL-E865, KLOE, KTeV, ISTRA+ and NA48 experiments. This analysis, in conjunction with precise lattice calculations of the hadronic matrix elements now available, leads to a very precise determination of |Vus| and allows us to perform several stringent tests of the Standard Model.

  1. Axion-like particles solve the $B\to K\nu\bar\nu$ and $B\to \pi K$ puzzles

    A minimal ALP model with mass near the pi0, couplings to photons, top quarks, and a sterile neutrino explains the B to K inv excess via off-shell sterile neutrino pairs and B to pi K anomalies via pi0 mixing.

    hep-lat 2026-05 unverdicted novelty 5.0

    New four-flavor smeared Möbius Domain Wall Fermion ensembles yield F_K/F_pi = 1.1962(34) as a precision test for inexpensive chiral fermion calculations in lattice QCD.
