Resummation of infrared renormalons in the pion electromagnetic form factor calculations
Shahin S. Agaev
Abstract
The pion electromagnetic form factor Fπ(Q2) is calculated at the leading order of pQCD using the running coupling constant (αS(Q2(1-x)(1-y))) approach. The resummed expression for Fπ(Q2) is found. It is shown that the effect of the infrared renormalons can be taken into account by scale-setting procedure αS(Q2) → αS(ef(Q2)Q2) in the leading order expression
