abstract

We have completed a lattice QCD calculation of $\Delta m_K$, the mass difference between the long- and short-lived K mesons. The calculation was performed on a $64^3 \times 128$ lattice using 152 configurations with physical quark masses and an inverse lattice spacing of $1/a=2.36$ GeV. While the statistical error approaches a relatively small size of 9%, several sources of systematic errors may have more significant effects. In this paper we will address studies performed on smaller lattices to estimate the systematic errors in our result.

  1. $B\to K{+}$invisible, dark matter, and $CP$ violation in hyperon decays

    hep-ph 2025-02 conditional novelty 6.0 of 10

    In a two-Higgs-doublet plus scalar dark matter model, hyperon decay CP asymmetries can reach parts in a thousand, far above the standard model, while still satisfying kaon and dark matter constraints.

  2. Flavor Constraints in a Generational Three Higgs Doublet Model

    hep-ph 2025-02 conditional novelty 5.0 of 10

    A generational three-Higgs-doublet model is constructed, and flavor constraints show that its additional Higgs bosons can be as light as about 1.5 TeV if the only flavor violation is the minimal amount needed to repro...
