Calculating $Δm_K$ with lattice QCD | | Bigeng Wang
; | | Date: |
3 Jan 2023 | | 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 $64^3 imes 128$ 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. | | Source: | arXiv, 2301.01387 | | Services: | Forum | Review | PDF | Favorites | |
