4 DESY at Zeuthen Particle Physics Experiments H1+HERMES at HERA Theoretical Physics Lattice supercomputing ILC Project physics + detector studies Particle-Astrophysics Baikal, AMANDA, IceCube high energy cosmic neutrinos Accelerator R&D develop components for VUV-FEL + XFEL PITZ: Photo Injector Test Facility Zeuthen Zeuthen well integrated in DESY rich program with specific flavors 4

5 HERA lumi upgrade: background conditions + stability improved 2004: 91 pb -1 highest lumi/year delivered so far 2005: 90 pb -1 by now, >1 pb -1 /day, ~150 pb -1 expected polarization 25-45% HERA end mid-2007: ~700 pb -1 totally, about equally e + and e - 5

6 Strong coupling α S α s ZEUS (82 pb -1 ) (inclusive jet γp) ZEUS (38 pb -1 ) (dijet DIS) ZEUS (39 pb -1 ) (inclusive jet DIS) CDF (87 pb -1 ) (inclusive jet pp) Bethke µ (GeV) α s (M Z ) = ± need ~1% precision from theory! 6

11 Neutrino Astro-Physics IceCube 1 km 3 Antarctic Ice 12

12 Neutrino Astro-Physics Amanda: many new results - sensitivity gets interesting 13

13 IceCube: : Neutrino Astrophysics First string deployed DOM Module Production 2450 m deep in Antarctic ice in January 05. also: simulation, reconstruction, analysis 1300 of 60x80 = 4800 modules assembled at DESY Zeuthen. 14

14 ILC: Global Design Initiative ~220 participants from all 3 regions mostly accelerator experts 16

15 HERA-LHC LHC-ILC DESY participation at the LHC: the bridge from HERA to the ILC DESY-CERN contacts start 17

16 Synchrotron Radiation use different features of laser in Atomic and molecular physics Biology Chemistry Material science High field and plasma physics to produce movies of chemical reactions real-time studies of formation of condensed matter imaging of bio-molecules with atomic resolution 18
