Description
We simulate a theory with two dynamical O(a) improved Wilson quarks
whose mass M is close the charm quark mass and
at three values of the lattice spacing ranging from 0.066 to 0.038 fm.
This theory is a prototype to study the decoupling of heavy quarks.
We measure the mass and cut-off dependence of ratios of gluonic
observables defined from the Wilson flow or the static potential.
The size of the 1/M corrections can be determined and disentangled
from the lattice artifacts.
The difference with the pure gauge theory
is in the percent range when two quarks with a mass of the
charm quark are present.
