Renormalon-based resummation for spacelike and timelike QCD quantities whose perturbation expansion has general form
Cesar Ayala, Gorazd CvetiÄ, Reinhart Kögerler
We present a generalisation of our previous approach of a renormalon-motivated resummation of the QCD observables. Previously it was applied to the spacelike observables whose pert…
Extending the LCSR method to the electromagnetic pion form factor at low momenta using QCD renormalization-group summation
Cesar Ayala, S. V. Mikhailov, A. V. Pimikov
We obtain the electromagnetic pion form factor (emFF) for spacelike mid-range of momentum transfer in QCD. We use renormalization group (RG) summation within the light cone…
The mass of the lightest gluelump
Cesar Ayala, Antonio Pineda
We give the most up-to-date determinations of the normalization of the leading renormalons of the pole mass, the singlet static potential, the octet static potential, and the gluel…
Towards unifying perturbative and Holographic Light-Front QCD via holomorphic coupling
Cesar Ayala, Gorazd Cvetic
We construct a QCD coupling in the Effective Charge (ECH) scheme of the canonical part of the (inelastic) polarised Bjorken Sum Rule (BSR) ${\overline…
