$|V_{us}|$ from $K_{\ell 3}$ decay and four-flavor lattice QCD
Using highly improved staggered quark (HISQ) Nf=2+1+1 MILC ensembles with five different values of the lattice spacing, including four ensembles with physical quark masses, we perform the most precise computation to date of the K→πℓν vector form …
