This meeting is organized by the US ATLAS Hadronic Final State Forum and SLAC. It is open to all ATLAS collaborators. This is a follow up on similar meetings held at the University of Victoria in December 2005, SLAC in March 2007, January 2008, and April 2009. The structure of the meeting is informal, with an emphasis on small working groups looking at various aspects of hadronic final state reconstruction using 2010 ATLAS collision data.

The tentative program includes guided discussion sessions with short introductions to general jet, missing Et, tau and b-jet reconstruction in ATLAS. These are followed by working sessions on selected topics of common interest. Exchange and informal discussions are encouraged. The workshop is concluded by a summary discussion session. Participants are invited to express their interest in possible working topics before and during the workshop.
