Renormalon subtraction from the average plaquette and the gluon condensate

A Borel summation scheme of subtracting the perturbative contribution from the average plaquette is proposed using the bilocal expansion of the Borel transform. It is shown that the remnant of the average plaquette, after subtraction of the perturbative contribution, scales as a dim-4 condensate. A critical review of the existing procedure of renormalon subtraction is presented.
