sPHENIX is a new detector at RHIC.

Friends,

Following the short, but useful discussion over at sphenix-physics-l, we 
should take the next steps to establish the topical groups. We suggest that 
each group will have two co-conveners to guide the organization within the 
group, coordinate with the other TGs and work with the software and 
simulation team to identify infrastructure needs and organize the overall 
workforce.

While this plan can of course be tweaked in the future, the proposal is to 
start with three topical groups, focussing on "Jet structure", "b-jet energy 
loss" and "Upsilon Spectroscopy". Each group is asked to demonstrate 
sPHENIX's capability to perform a state-of-the-art measurement for the 
respective topic. The details of which measurement to go for, following the 
discussion we already had, should be worked out in each group.  The goal is 
that each "money plot" being produced should clearly prove the sPHENIX 
capability for one particularly ambitious measurement, which then naturally 
encompasses the ability to perform various simpler day-1 and day-2 
measurements along the way  (e.g., if one can convincingly show good 
performance for b-jet R_AA, inclusive jet R_AA, dijet A_J,... capabilities 
are clearly also in hand etc etc).

To gauge interest in the three groups, we have set up a doodle poll here:

Please pick the groups you are planning to actively contribute to (or at the 
very least follow closely). 

Finally, please suggest your colleagues  or yourself (don't be shy!) for the 
convenership of these groups. We will try to get this off the ground as soon 
as possible - any convener suggestions received by the end of this week will 
be particularly helpful. 


Cheers,

Gunther and Dave
