Results for light pseudoscalar mesons
, 2010 We present the current status of the MILC collaboration's calculations of the properties of the light pseudoscalar meson sector. We use asqtad staggered ensembles with 2+1 dynamical flavors down to $a \approx 0.045$ fm and light quark mass down to 0.05 $m_s$.

Decay Constants of Pseudoscalar Mesons
, 2013 For purely leptonic decays of pseudoscalar mesons, the decay rates are related to the product of the relevant weak interaction-based CKM matrix element of the constituent quarks on the one hand, and the strong interaction parameter, the decay constant, which is related to the overlap of the quark and antiquark in the meson on the other hand.
