This is a proposal developed by consensus among four members of an ad hoc subcommittee of the Executive Board: Fry, Giorgi, Witherell, Wormser, after a meeting with interested parties, many one-on-one conversations, written comments, and a document submitted by the computing group. There was an extraordinarily wide range of opinion on how these structures should be set up. The following proposal was reached by building on those areas in which there was a fairly wide consensus. Although most people we have talked to agree with much of this proposal, many disagree with at least one aspect of it. Most often the disagreeing views are of opposite direction. We are going to be discussing this proposal in the Executive Board next week at the collaboration meeting. If you have strong objections to parts or all of this proposal, or even if you want to express your agreement with it, you should communicate by e-mail to one or all of the four people mentioned above.* Or, if you would prefer, you can send comment to the Executive Board as a whole through the BFMAIL list. *[fry@cernvm.cern.ch,wormser@frcpn11.in2p3.fr,giorgi@pisa.infn.it, witherell@sbhep.physics.ucsb.edu] ------------------------------------------------------------------------------ There are three positions which would be appointed by the Exec. Board. The rest of the organization would be worked out by them, and with the computing group. The three positions would be 1)Reconstruction manager. 2)DST analysis manager. 3)Physics coordinator. These are discussed in turn. 1)RECONSTRUCTION MANAGER This person is responsible for the content of the reconstruction program, for coordinating the reconstruction efforts of the various detector groups, for recruiting people to take responsibilities in this area, and for making sure that the reconstruction program is completely integrated into the software system developed by the computing group. The reconstruction manager will be co-head of an analysis software group, separate from the computing group, although reporting to the computing group on the computing system aspects. He or she will convene meetings of reconstruction leaders from each detector group. In addition, the reconstruction manager should report to the computing group on the integration of the reconstruction package into the software system, since the ultimate responsibility for the standards of the software system is with the managers of the computing group. The primacy of the computing group on setting these standards must be understood from the beginning. The reconstruction manager is a full time position, and the person who takes on the job should have no other significant responsibilities on BABAR or another experiment. It requires the same commmitment as a system manager, during the time of appointment. The reconstruction manager should be appointed for a two year period, renewable. There will also be a simulation manager, who will operate as an assistant to the reconstruction manager, and as such will not be included in the initial three appointments. 2. DATA SUMMARY TAPE (DST) ANALYSIS MANAGER This person is responsible for taking the reconstructed data and getting it ready for everybody in the experiment to do physics analysis with. It therefore involves coordinating work on developing analysis tools needed for DST analysis, especially those using information from multiple detectors. This would involve coordination with the computing group and with the reconstruction manager. The DST Analysis Manager would be co-leader of the analysis software group. It is also a full time position, with no other significant responsibilities during the time of the appointment. The manager is appointed for two years, renewable. SUMMARY of 1 and 2: The analysis software group would have two co-leaders, the Reconstruction Manager and the DST Analysis Manager. 3.PHYSICS COORDINATOR The third position is someone worrying about the physics of the experiment in the purest sense. The work he would be coordinating might include a working group to study various strategies for measuring the third mixing angle, or to study the proper tests to diagnose non-standard CP violation, or to consider the highest priority tau physics problems that should be taken up by BABAR at turn on. This also is the focus of contact with theorists working on BABAR physics problems. This person is NOT responsible for developing a large software structure during the construction period, as the first two persons are. Thus it is called a coordinator. NOTE: A separate Phyics analysis board or panel may be of interest, to work with the physics coordinator. The consensus was to not set such a board up until we reach agreement on the above positions, and possibly until the physics coordinator is in place. Distribution to: DISTRIBUTION
