RHIC II Science Workshops A science vision for
the RHIC future Begun November, 2004
Provide a science case for the future RHIC
program that makes clear its importance in the
broad scientific arena, including a future Long
Range Plan.
What are the most crucial measurements to be made
at RHIC over the next decade? What compelling
new insights would these measurements bring to
our understanding of fundamental issues of broad
scientific interest? Of these measurements,
which ones require detector or collider
upgrades? Why should these measurements be made
at RHIC and not LHC?

Nov. 11-12 Workshop

• Working Group Summaries
• Aim for detailed written reports, directed at
  RHIC community
• Initiate work on Final White Paper
• Overview summary aimed at broader NP general
  scientific community
• Writing Committee

• The goal for this workshop is to settle on the
  content and packaging of the White Paper
• Identify the main points (Tonys A List
  measurements)
• What level of detail?
• Open questions (e.g. further work needed
  simulation, theory)
• Identify the target audience
• Set up the process for getting it done
• Writing assignments, schedule, future meetings
