PROPOSAL FOR COMMUNITY REVIEW OF PARTICLE PHYSICS SCIENCE OPPORTUNITIES Dear STFC particle physics grant holders, As you hopefully know, PPAN has asked the new Particle Physics Advisory Panel (PPAP) to prepare an updated PP roadmap, for input into an STFC science roadmap. PPAN has asked all five new advisory panels to prepare respective first-pass roadmaps by September 2009. A brief summary of the PPAP terms of reference, membership, and first thoughts on the process can be found in our recent presentation to the STFC Town Meeting at the Oxford IoP HEPP annual conference: http://indico.cern.ch/sessionDisplay.py?sessionId=26&slotId=0&confId=40295#2009-04-07 The timescale is clearly rather tight, and the PPAP would like to move forward with plans for a community review of our science opportunities. There was general support for this notion expressed among those present at the Town Meeting. We had originally thought of having three 1-day meetings, separated in time and locations. However, we received strong feedback that a single, central location, and contiguous meetings, would in fact be preferable, and would maximise the probability of significant community representation across the 3 days. After consideration of several obvious possibilities, we would like to propose a review extending over 3 days, provisionally to be held in Birmingham, on July 13, 14 and 15. The dates have been explicitly chosen so as to avoid known other meetings, to be far enough away to allow thorough preparation, yet be soon enough to allow digestion of the outcomes, and time for community feedback, prior to the September deadline. We consulted on the location, and were reassured that Birmingham is relatively convenient to get to; indeed, some preference was expressed for it even by our colleagues in Scotland, due to the availability of cheap flights. Our Birmingham colleagues have generously provisionally agreed to this proposal, and a suitable room (for up to 200 people) is available. The scope of the reviews is provisionally suggested as follows: Day 1: flavour physics, QCD, energy frontier 1. Day 2: energy frontier 2. Day 3: neutrinos and non-accelerator experiments. Again, we have tried to suggest a framework that will maximise the probability that people will attend for more than one day, so that we can enable broad community input into each area. The details of the dates, location, and purview of each meeting are of course subject to opinion, and we have tried to optimise subject to the many boundary conditions. We are drawing up 'programme committees' of about ten community members for each day, who will be asked to define the scope of presentations and discussions in each area. We hope to invite members of these committees in the next week, so that preparations can begin. At this stage we would appreciate your comments on this provisional plan, in particular if there are any major issues that we might have overlooked. Please send feedback ASAP. Thanks and best wishes, Phil (for the PPAP)
