Resurgence as a new tool for computing inclusive hadronic observables in Quantum Chromodynamics*

We study the QCD Adler function in the energy region ≈0.7−2.5 GeV, in which the non-perturbative effects become dominant. Our analysis is a renormalon-based evaluation using transseries within the resurgence of the Renormalization-Group-Equation and does not require the Operator-Product-Expansion.
