For the coming ~5 years, LHCb will do this job in the b and c quark sectors. To follow-up this progress, collecting 50 ab−1 or more at Υ(4S) energy with e+e− storage rings by the end of the next decade would be a significant milestone, if this can be realised at a moderate cost. • The INFN Super Flavour Factory project team proposes a novel scheme to obtain luminosity of ≥1036 cm−2s−1, two orders of magnitude more than what has been achieved up to now, without increasing the beam currents. This is a distinct advantagefor some of the machine operation aspects and background to the experiment, as well as for the running cost of the machine. This idea of obtaining a high luminosity with tiny beam spots at the collision point based on very small emittance beams and crab waist collisions could revolutionize the design of the future colliders. Therefore, westrongly support the R&D effort to see if such a machine can really be built. ECFA report summary –Part 2 • • • The current tests at DAFNE are promising and we would like to congratulate the team for this impressive achievement. However, a substantial amount of work is still required for producing a Technical Design Report, which will be a base for establishing an international consortium for the realisation of the project. A strong core team of experienced accelerator physicists and engineers based at one location should be established already for the TDR work. Without it, contributions from the various interested laboratories cannot be effectively utilized. A strong team of experienced machine physicists will be needed also for the operation. This machine has to achieve its design luminosity in order to be truly competitive. Given the complexity of the project, we feel that a clear plan containing realistic technical milestones and resource requirements together with a strategy how to obtain them is needed as a necessary condition for an approval of the project. Such a plan should aim at obtaining an integrated luminosity of significantly more than 50 ab−1 by not much later than the end of the next decade. Given the very ambitious time scale, a clear decision taking process must be established soon. The European Strategy procedures • 3. Recognition and follow-up of projects by the European Strategy Sessions of Council • 3.1 Emerging projects in their "initial phase" Given the strategic importance of emerging projects, the Strategy Secretariat will need to interact with projects deemed to be relevant to the European Strategy for Particle Physics right from their earliest phase and submit their plans to the European Strategy Session of Council to ensure that they receive the necessary priority and attention. The basic procedure to monitor, to report on and ultimately to recognise such emerging projects is as follows: • The Strategy Secretariat will identify the planned projects that are relevant for the implementation or further development of the European Strategy for Particle Physics, and will inform Council about their status and plans. The Strategy Secretariat will establish formal lines of communication with the projects, as required, at an early stage, with typically one or two persons reporting to the Secretariat. ECFA, in its role of monitoring the ongoing implementation of the European Strategy for Particle Physics in the CERN Member States, will naturally develop a bottom-up view of the national involvement andinterest in such "initialphase" projects. European strategy procedures (2) • • • If and when a project relevant to the European Strategy for Particle Physics reaches maturity and a clear plan towards approval emerges, the Strategy Secretariat will present this plan to the Council and ask the Council to take note and comment, in particular on the foreseen European role in the project. The Council should be informed about important considerations such as technical feasibility, scientific objectives, resources, schedules and project organisation, enabling it to comment on the project plan and to discuss priorities between projects. The Strategy Secretariat will work with the projects to promote implementation of the Council's comments and European involvement in the period leading up to approval.1 During this period, the project will be presented to the SPC, which will advise the Council as to whether or not the project should be recognised, and the formal channels of communication between the European partners and the Strategy Secretariat will be defined. Projects that successfully reach the end of this phase and are being approved by their host organisations will be brought to the Council for recognition as an ongoing project within the European Strategy for Particle Physics. Once a project has been thus "recognised" it will be deemed to be in its ongoing construction and operation phase and followed up according to the procedure described in section 3.2, below. . In summary • Three steps Initial Presentation to Council( Done in Sept 2008): Council takes note SPC advises council : Council takes note and comments: March 2009 Formal recognition once the project is approved The US process • One offshore Super B factory project official part of the US P5 report in « scenario B » Interactions with Japan • KEKB upgrade part of KEK roadmap • Nobel prize effect? • Interference with SuperB project negative or positive? • The « one joint program , two phases » model ? TDR organisation TDR scope and contents • TDR scope definition – By contents, eg « ready to build » documents – By schedule, eg « needed in Nov 2010 » for project approval • 5 different documents – – – – Physics, Machine, Site, Detector, Computing Not necessarily issued at the same time « Distance to build » not necessarily the same My personal view: site document should be « ready to build », Machine « half iteration away, detector and computing one iteration away, physics book post TDR Next milestones • Orsay collaboration meeting Feb 15-18 – Official launch of the TDR phase – Open session on Feb 17 – Parallel sessions: focus on joint sessions • Computing and site • Computing and detector • Computing and machine? • Physics workshop in Warwick, April 15-18 • MiniMAC in April as well Conclusion • SuperB project approval is progressing well on different fronts • Key signal from Italian government expected in 2009 • Official TDR launch in Februray 2009 in Orsay
