The hadronic running of the electromagnetic coupling and electroweak mixing angle
The hadronic running of the electromagnetic coupling and electroweak mixing angle
We present results for the hadronic running of the electromagnetic coupling and the weak mixing angle from simulations of lattice QCD with $N_f=2+1$ flavours of $O(a)$-improved Wilson fermions. Using two different discretisations of the vector current, we compute the quark-connected and -disconnected contributions to the hadronic vacuum polarisation (HVP) functions …
