Description
We update our previous results and also determine $F_K$ and $F_\pi$ separately using Möbius domain-wall fermions computed on gradient-flowed $N_f$ = 2 + 1 + 1 highly-improved staggered sea-quark ensembles. We use five values of the pion mass ranging from 130 $\le$ $m_\pi$ $\le$ 400 MeV, four lattice spacings of a $\sim$ 0.15, 0.12, 0.09, 0.06 fm and multiple lattice volumes. The physical point, continuum, and finite-volume extrapolations are performed with relevant mixed-action effective field theory expressions.
