摘要：
We give the analytic expressions of the eight master integrals entering our previous computation of two-loop light fermion contributions to gg --> H and H --> gammagamma. The results are expressed in terms of generalized harmonic polylogarithms with maximum weight four included. (C) 2004 Elsevier B.V. All rights reserved.
