摘要
En 中文
Massive on-shell operator matrix elements and self-energy diagrams with outer gluon lines are calculated analytically at O(alpha(2)(s)), using Mellin-Barnes integrals and representations through generalized hypergeometric functions. This method allows for a direct evaluation without decomposing the integrals using the integration-by-parts method. (C) 2007 Elsevier B.V. All rights reserved.
