Description

The one-loop gluon condensate contribution to the 0++ glueball correlation function will be calculated using a non-zero momentum insertion of the condensates. It is demonstrated that the operator-product expansion coefficient is free of infrared divergences, supporting the concept that the condensates contain the long-distance effects in the operator-product expansion. It is anticipated that these results will be important for improved sum-rule estimates of the glueball mass and width. (orig.)
