Description
In this talk we present the ongoing effort of the Fermilab Lattice and MILC Collaboration to compute the smeared $R$-ratio using $N_f=2+1+1$ HISQ gauge-field ensembles. We discuss closure tests for mock data which incorporate taste-breaking and finite-volume effects to mimic real light-quark connected vector isovector correlation functions. This enables a detailed comparison between different spectral reconstruction methods, suitably adapted to include staggered oscillations, paving the way to real lattice data applications with controlled systematic errors.
