Resurgence analysis of the Adler function at O $$ \mathcal{O} $$ (1/ N f 2 $$ {N}_f^2 $$ )

Abstract We compute non-perturbative contributions to the Adler function, the derivative of the vacuum polarization function in gauge theory, using resurgence methods and Borel-summed gauge field propagators. At 2-loop, to order 1/N f , we construct the full 2-parameter transseries and perform the s...
