Ghost-gluon coupling, power corrections, and ^MS¯¯¯¯¯ from lattice QCD with a dynamical charm

This paper is a first report on the determination of ^MS¯¯¯¯¯¯ from lattice simulations with 2+1+1 twisted-mass dynamical flavors via the computation of the ghost-gluon coupling renormalized in the MOM Taylor scheme. We show this approach allows a very good control of the lattice artefacts and confi...
