@article{10272/10496, year = {2003}, url = {http://hdl.handle.net/10272/10496}, abstract = {We present a study of αMOM(p) at small p computed from the lattice in the quenched approximation (nf = 0). It shows a dramatic proptop4 law which can be understood within an instanton liquid model. In this framework the prefactor gives a direct measure of the instanton density in thermalised configurations. A preliminary result for this density is 5.27(4) fm−4.}, publisher = {Springer Verlag}, title = {The strong coupling constant at small momentum as an instanton detector}, doi = {doi:10.1088/1126-6708/2003/04/005}, author = {Boucaud, Ph. and Le Yaouanc, Alain and Leroy, J.
