H->bb Weekly Meeting Ricardo Gonçalo (RHUL) HSG5 H->bb Weekly Meeting, 26 April 2011

News! News! News! About 147 pb -1 collected with stable beams so far – 50ns bunch spacing – 480 colliding bunches Typical peak pileup values around collisions per bunch crossing Ricardo GonçaloHSG5 H->bb - 26/4/20112

News! News! News! Meeting in the last few weeks (anything we should know?): LHC Physics Center (LPCC): Status of Higgs and BSM searches at the LHC on April 11-12: Workshop on combined performance for 2011, on 14 April: New meeting on procedures for statistical interpretation of ATLAS results on April 15: Coming up: 4th workshop on Higgs Cross Sections for the LHC at BNL on May 4-6: Ricardo GonçaloHSG5 H->bb - 26/4/20113

News! News! News! Theory & generators: – Wbb production in POWHEG now implemented: Download code from: – HDECAY 3.60 released: Releases & data: – 2011 reprocessing plans listed here: – Analysis for Summer conferences to be done with rel.16 – Data taken up to ≈1 August will later be reprocessed with rel.17 List of deliverables for rel. 17: – Not clear about Pixel re-clusterization, but should be in rel.17 – MC11 – decisions on geometry, B-field map etc for MC generation: Evgen with 16.6.X.Y and reco with 17 as part of reprocessing campaign after summer conferences Ricardo GonçaloHSG5 H->bb - 26/4/20114

WH Task List Ricardo GonçaloHSG5 H->bb - 26/4/

Milestones & other issues Fast monitoring plots – Wisconsin following up: progress? Dubna: – Already in 3 weeks! – Final rehearsal from our side on May 10 – Reminder of Summer conferences: – Data estimates from February seem to be on track! – PLHC 2011: 6 June ( L ≈ 0.6 fb -1http:// – EPS-HEP 2011: 21 July ( L ≈ 1 fb -1http://eps-hep2011.eu/ Ricardo GonçaloHSG5 H->bb - 26/4/20116

Ricardo GonçaloHSG5 H->bb - 26/4/20119 DateMilestones wish list 17 MayDubna workshop – analysis frozen After this: add data to un-boosted analysis and prepare for result approval Concentrate more effort on boosted VH with a view to obtaining results quickly 10 MayReview results with 2011 data from cut-based and multivariate analyses 3 MayMargin for dealing with unforeseen problems 26 AprilStart looking at 2011 data if enough is available. Any surprises? How does the MC describe the new data? By now we should have a reasonable idea of results from the multivariate analysis 19 AprilEnd of 2 weeks of beam scrubbing. (I’m away for Easter) 12 AprilBy now we should have a reasonable idea of the exclusion of the cut-based analysis First report on MVA preliminary results – establish plan for getting results by Dubna 5 AprilIdentify the worst systematics and discuss any possible improvements: Any changes needed in analysis cuts? Any study necessary for corrections to some systematic effect? Multivariate analysis: iterate on preselection cuts, methods, questions Assign tasks – divide the work to achieve better results! 29 March Establish analysis cuts: If possible as result of optimization Use 2010 data to develop cuts and show that data is well described by background MC Start evaluating systematics 22 MarchIterate on analysis cuts – why is each cut applied at each particular value? Start iteration on multivariate methods to improve analysis

Reconstruction issues Muon CP group recommendations for release 16: – Reconstruction efficiency and isolation efficiency scale factors, momentum smearing functions – Jet/Etmiss recommendations for jet cleaning in release 16: – Medium jet cleaning should give similar rejection to rel 15 cleaning but with better efficiency – Tight jet cleaning should not be used – still under discussion – New!: Final b-tagging calibrations for release 16 based on full 2010 data: – e/gamma recommendations for energy scale and resolution in release 16: – – And rescaler tool: Standard Model W/Z group baseline selection for release 16 (next 4 slides): – See discussion in W/Z group SharepointdiscussionSharepoint – Also, finer points (and perhaps the not so fine) still being discussed Ricardo Gonçalo10HSG5 H->bb - 26/4/2011
