Presentation Transcript

  1. Physics Introduction:all presentations this week focused on ICHEP Guy Wilkinson University of Oxford LHCb week 30/6/10 St Petersburg

  2. Minor addition to agenda Short presentation on Ф production by Moritz Karbach, immediately after coffee on Thursday – several other presentations have generously agreed to ‘save’ 5 minutes so we should still fit within the time budget

  3. Results expected for ICHEP (22-28/7/10) After last s/w-analysis week, certain analyses identified as capable of providing real physics results for ICHEP, and referees appointed: • 1) J/ψ studies [referees Egede and Uwer] • 2) b-bbar x-sec through D0μnX [referees Lefrancois and Gershon] • b-bbar x-sec through D*μn (but thismay require more lumi) • [referees Schwarnicki and Patel] • 4) -bar,  (and related V0) studies [referees Teubert, Calvi, Harnew] • 5) pbar-p ratio etc [referees Jones and Matteuzzi] • 6) open charm x-section [referees Merk and Clark] Other analyses also look very promising, and may deliver at the least nice plots – perhaps more (but if more, we would need to decide soon), eg. • W,Z studies; Inclusive Ф; charged track distributions… Finally, ongoing studies on our core physics topics are of vital importance. Here we expect eg. signal region distributions showing background levels (and signals!) and studies using early data to validate analysis strategy.

  4. Timescale for ‘physics’ analyses Analysis web-pages set up (all happen to be under F WG) https://twiki.cern.ch/twiki/bin/viewauth/LHCb/FlavourPhysics#Analyses_notes_and_papers_under Initial analysis note drafts request for start of this week (most of these exist but I don’t think they have all made it to web-pages) Presentations scheduled today and tomorrow. Interaction with referees encouraged this week, and complete analysis notes requested for end of week If referees agree that analysis is in sufficiently good shape we will attempt to approve it on Friday (9th July) next week. My assumption is that analyses can be approved even if some ‘final’ numbers are missing (but it depends on the numbers…) and that updates with these final numbers can be shown later. Conference notes are then to be drafted for following week.

  5. Approval of other material Tuesday meeting of July 13th will be used to approve other material. Important that this material is exposed and agreed on in detector subgroups / physics working groups / tasks before this meeting! Internal notes to support this material are not essential, but are of course very welcome. It is assumed that no conference notes (ie. public documents) will be produced to support this material at ICHEP, but if you think differently then we can discuss.
