Abstract

We could successfully complete our research project on Higgs-production by calculating the soft andvirtual corrections in next-to-next-to-leading order (NNLO). We also completed our study on the transverse momentum distribution of Higgs proruction at NNLO in the small transverse momentum region by resumming the logarithmic terms to all orders.
B)
We organized the First Young-Researchers QCD-Network Meeting QCDNET-YR Zurich, Zurich Switzerland, 19-21 February, 2001. The young researchers presented their results in 25 talks andnew projects have been initiated in the discussion sessions.

In the given period our group participated in the publications as follows:
