Superasymptotic and hyperasymptotic approximation to the operator product expansion
Cesar Ayala, Xabier Lobregat, Antonio Pineda
Given an observable and its operator product expansion (OPE), we present expressions that carefully disentangle truncated sums of the perturbative series in powers of from the…

The regularization and determination of the Yang-Mills vacuum wave functional in three dimensions at O(e^2)
Sebastian Krug, Antonio Pineda
We complete the computation of the Yang-Mills vacuum wave functional in three dimensions at weak coupling with O(e^2) precision. We use two different methods to solve the functiona…

The Yang-Mills vacuum wave functional in three dimensions at weak coupling
Sebastian Krug, Antonio Pineda
We compute the Yang-Mills vacuum wave functional in three dimensions at weak coupling with O(e^2) precision. We use two different methods to solve the Schroedinger functional equat…
