Query: Superasymptotic and hyperasymptotic approximation to the operator
  product expansion   Given an observable and its operator product expansion (OPE), we present
expressions that carefully disentangle truncated sums of the perturbative
series in powers of $\alpha$ from the non-perturbative (NP) corrections. This
splitting is done with NP power accuracy. Analytic control of the splitting is
achieved and the organization of the different terms is done along an
super/hyper-asymptotic expansion. As a test we apply the methods to the static
potential in the large $\beta_0$ approximation. We see the superasymptotic and
hyperasymptotic structure of the observable in full glory.
