Abstract :
The connection between renormalons and power corrections is investigated for the typical infrared renormalon integral assuming the effective coupling constant has an infrared fixed point of an entirely perturbative origin. It is shown that the full answer differs from the Borel sum by a power correction. A comparison with the analogue results when the fixed point is generated by the explicit addition of non-perturbative power suppressed terms is given.
