Lattice calculation of the R-ratio smeared with Gaussian kernel

Constantia Alexandrou, Simone Bacchio, Alessandro De Santis +15

The ratio $R (E)$ of the cross-sections for $e^{+} e^{-} \to$ hadrons and $e^{+} e^{-} \to μ^{+} μ^{-}$ is a valuable energy-dependent probe of the hadronic sector of the Standard Model. Moreover, t…

Probing the energy-smeared R-ratio on the lattice

Constantia Alexandrou, Simone Bacchio, Alessandro De Santis +15

We present a first-principles lattice QCD investigation of the $R$ -ratio between the $e^{+} e^{-}$ cross-section into hadrons and that into muons. By using the method of Ref.[1], that a…
