David d'Enterria -
Low-x QCD physics from RHIC and HERA to the LHC (hep-ex/0610061) talk presented at HERA-LHC workshop, June 2006

Background and Aim:

The impact of measurements made at HERA, present and future, on the physics of the LHC is potentially large. However, this potential is currently not as well explored as e.g. the more obvious connection between the Tevatron and the LHC.

The most obvious area of impact is in the determination of proton structure from very low to very high x, which is measured precisely at HERA. Others topics include QCD production of heavy flavors and the study of multi-jet final states, energy flows and structure of underlying events. A unique feature of HERA is the photon, which, depending upon its virtuality, can be hadronic or point-like, enabling to effectively turn on and off the internal structure of one of the beam particles. Finally, the area of diffractive and forward physics, where HERA data have made a large impact in the last decade, is of growing interest to LHC experimentalists as a window on high density and low x QCD and as a search channel for new physics.

Time plan and organization:

The HERA - LHC workshops will be held yearly, the meeting 2007 is at DESY, the meeting 2008 is at CERN.

Presentation of results:

We will have proceedings, with a summary report from each working group and individual contributions. The proceedings will be printed and published electronically.
