## 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  (Tony’s “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...
