Working Group Meeting (McGrew/Toki) Discussion Items (focused on R&D software section) Goals of Simulations Simulation detector models to try Simulation cpu requirements & datafile size Software Modules Software Infrastructure Computing Hardware Manpower Proposed Costs for R&D proposal Presentations; Jungdoo; UNO software at CSU Chiaki; Physics analysis,  finding & CP sensitivity Clark; UNO software, the analysis chain SATURDAY meeting

Friday Afternoon Discussion Clark, Brett, Dhiwan, Aidong, Walter (Chiaki, Jungdoo) biweekly 1 hour phone meetings develop/implement software using descriptions of analysis chain from experts focus on serious analysis of VLBL measurement with UNO baseline detector and BNL beam Develop schedule in few weeks plan for progress reports in future UNO meetings target VLBL results for PRD in ~1 year => Seeking interested UNO collaborators

Determine sensitivity of UNO detector in Proton decay in p →   e and p  K. Very Long Baseline measurements of sin 2  13 and  cp using  disappearance and e appearance (VLBL àla BNL) R&D results for the UNO detector proposal 2 nd aim for Phys.Rev. D. paper on VLBL Main Goals of Simulation Effort

Detector Models to be Simulated Main baseline UNO (60x60x180m, 20” & 8’’ PMTs, etc.) start with baseline design and determine sensitivity  Optimize sensitivity and minimize cost Parameters to vary detector shape and dimensions no. of PMTs size of PMTs reflectivity of material water absorption length water scattering length dead space inner-outer section electronics (timing and adc resolution) hadronic modelling & parametrizations?  Above parameters would require a separate simulation run Detector Models to be Simulated

Other simulation parameters to be varied L 0, distance between UNO and BNL (2767km) , earth density (~3gm/cm 3 ) beam parameters (energy distribution, bkgds) overburden (4200mwe depth of UNO) Above parameters can be achieved with Reweighting incident event sample Other Issues detailed background studies (   backgrounds) how sensitivity is limited to background uncertainties detector calibration issues (or limitations) Figure of Merit (specifying sensitivity of measurements) what type of statistics? Comparisons to competing expts, etc. off-axis?, Nova?

MANPOWER Programmer/Physics support person at central site HEP physics background experienced C++ programmer, LINUX administrator support person accessible by offsite users Graduate student support students who finish coursework, but have not joined their thesis experiment are ideal candidates 12 month support for UNO software development Hourly consultant support for LINUX hardware and setup some success at CSU with hourly support ($75/hour) may be possible to share with multiple sites (remote login) Guidance from senior physicists (no cost) help direct & guide students at local sites
