Background in HERA Experiments
Workshop is timely:
Background in HERA collider expts.:
- ep: “worst-case scenario”:
- e+ with SR bad vacuum- p large BG
BG solved in an heroic, collaborative effort by HERA and HERA-expts.

Luminosity
Workshop is timely:
HERA luminosity is star-ting to surpass the 2000 values:
- new record: 2.9x1031cm-
2s-1
- HERA I design: 1.5x1031
- HERA II designs: 5x1031

Lepton polarisation
Workshop is timely:
O(40%) polarisation has been achieved for all 3 experiments
(optimisation still to be completed O(50%))

HERA II Luminosity
Workshop is timely:
operation of HERA is getting more efficient and reliable(600 nb-1 per fill of 12 hours achieved)
luminosity goal HERA II ~(>?)700 pb+1 e+/e- both pol. until mid 2007

Summary
• HERA I has already contributed much to the understanding of high energy QCD (SF – diffraction – S – “HERA-events” + …)
• HERA II is getting under way – it should have an other significant impact on our understanding of QCD (SF at high and low x – parton correlations + … )
• LHC is progressing towards first data taking in 2007 – make sure that we do not miss measurements at HERA which are important for LHC physics
• stimulate theoretical and phenomenological work and develop new tools re-quired to understand the complex physics of final states at HERA and LHC
We look forward to an inspiring and successful workshop and a fruitful HERA-LHC scientific collaboration
