1 Plans for the SUSY MET PAS and Current MET Status Kenichi Hatakeyama (Baylor) Henning Flaecher (Rochester) MET-SUSY PAS Kick-off Meeting April 28, 2010

2 MET-SUSY PAS The focus of the MET-SUSY PAS is “MET performance” in inclusive and jet events. Studies of MET in events with leptons/photons will go to MET-EWK PAS, and MET modeling for SUSY analyses will go to SUSY PAS. April 28, 20102

3 Timeline Schedule:  Draft 0 with abstract, introduction, list of sections and figures: 30-April  Summary during Physics Week: 17-May  Plans for PAS in JetMET: 31-May  Dataset frozen on 31-May, analysis notes and PAS released by: 7-June  Pre-approval in JetMET meeting: 15-June  MET ARC green light: 23-June  MET approvals: 30-June Still subject to change. We have to define the study which is achievable in this time frame. April 28, 2010 https://twiki.cern.ch/twiki/pub/CMS/JetMET/JetMETtimelineForICHEP.pdf 3

4 A Few Notes  Sharing wisdom  Sharing Results  Collect information https://twiki.cern.ch/twiki/bin/viewauth/CMS/METichepPAS2 April 28, 20104

5 MET-SUSY PAS Contents Developments w.r.t. the previous MET PAS  7 TeV data! (1-10 pb -1 ) Repeat many of December data MET studies with 7 TeV data Study MET in various dijet event topology, higher jet energies (or HT), higher multiplicities (=2, =3, >=2, >=3, etc). Need to define studies so that we are studying MET performance but not QCD  Type I & II corrections for CaloMET Plan to have (1) CaloMET, (2) TypeI+II MET, (3) TcMET, (4) PfMET, and (5) MHT in various event topologies  MET significance  Updates on noise cleaning Cleaning tools beyond the simplistic topological cuts (e.g. using timing information) are under development and to be documented April 28, 2010 https://twiki.cern.ch/twiki/bin/viewauth/CMS/METichepPAS2 5

6 MET-SUSY PAS Outline  Introduction  Data sample definition  Updated description of noise cleanings and beam-induced background: tcmet people (mainly ecal cleaning), HCAL DPG (HF and HBHD cleaning), Ronny R (beam halo)  brief description of MET algorithms Description of type-I and type-II MET Ulla G., Dayong W. Description of MET singificance Freya B  MET performance in inclusive sample Basic MET distributions MET resolution versus sumet Artur A, tcmet people (TBC), Finn R  MET/MHT performance in jet studies Basic MET/MHT distributions MET and MHT resolution Artur A, tcmet people (TBC) Henning F., Burt B, Rob B, Bryn M, Markus S, Niki S Robert S  MET decomposition studies using thrust axis Chris R, Artur A, Maria S  MET decomposition studies using dijet bisector axis Jared S, Bill G, Harold N  MET performance in heavy-flavor events: Robert S  MET significance: Freya B April 28, MET Study in pileup events (Robert S) Study of MET source (Finn R) are also suggested.

7 What Do We Want to Achieve Today?  Get to know each other!  Review the status and plan of each contribution Check the scope of each analysis and feasibility Make sure all important items are well covered  Any new idea?  After the meeting, make the PAS draft 0 with abstract, introduction, list of sections and figures April 28, 20107
