Frontiers in QCD
This meeting is a follow-up to a workshop "QCD at High Energies/ Frontiers in QCD", Beijing September 2004
Both meeting are sponsored by Sino-German Center for Science Promotion (jointly founded by the National Natural Science Foundation of China (NSFC) and the German Research Foundation (DFG))
Meetings want to promote exchange and cooperation between Chinese and German scientists:several of Chinese participants have had prolonged stays in Germany, many of whom at DESY/Univ. Hamburg

DESY
• DESY has a long successful history in three areas of basic science and high tech :
– Particle physics (one of 5 laboratories world wide),
– Research with X-rays (synchrotron radiation) and
– Accelerator development.
• These topics stimulate each other and constitute the basis for the future of the laboratory.

DESY’s Accelerators
HERA built with major contributions from Italy, France, Poland, China etc.
DESY operates today 16 km of accelerators for:
- Particle physics
- photon science

QCD and DESY
DESY (together with the University of Hamburg) has a strong and long track record in QCD:
Gluon discovery early studies of QCD in e+e- (e.g. string fragmentation) at PETRAHERA (many aspects of QCD)Theory (Hamburg and Zeuthen)Lattice QCD
Future:Working on : LHC (will base in many respects on results from HERA)ILC

How Strong is the Strong Interaction?
003.01186.0 s
Unification??
s(MZ) = 0.1186 0.0011 (exp.) 0.0050 (th.)
s is derived from structure functions and other measurements

The Inner Structure of the Proton
A measure of the density of quarks and gluons in the proton is provided by the Structure Function
Knowledge of SFs is of vital importance for LHC physics

Summary
• Welcome to Germany and DESY
• Pleased to have you here,
– where a strong Sino-German collaboration has flourished for many years
– Where QCD has been and will be studied in many respects
I wish you and the Sino-German workshop an exciting week
