# What is the maximum distance for the action of the strong nuclear force?

If the strong nuclear force is carried by virtual fermions, they ought to be limited in range by the uncertainty principle. Can anybody calculate the maximum distance and tell me whether the decrease in strength with distance is abrupt at the end, or follows an inverse-square law, or whether some other kind of...
