8 CDF at IFAE IFAE JOINED CDF ON MAY 2003 IFAE Goals at CDF:Thesis for students with physics data Training on Hadron Collider Physics before the LHC CDF is a first-class experiment at the energy frontier

9 IFAE-CDF Commitments IFAE group is leading the data quality monitoring effort in CDF and acts as Data Quality Manager (DQM) IFAE implemented global DQM Automated Systems to characterize the quality of the data with emphasis on the quantities relevant for physics analyses Online & Offline DQM Automated Expert Systems Maintenance of Good Run Lists (DQM Online+Offline diagnosis) WWW documentation & Statistics IFAE is responsible of DQM Operation Regular Reports to CDF Online Support to Shift Crew operations (DQM contact person) IFAE charges & responsibilities were formally established in a MoU signed together with CDF and FNAL Directorate

10 DQM Online Model for CDFOnline Monitors (C++ based) produce online histograms to monitor the basic performance of the different sub-systems (occupancy levels, HVs) dead channel Expert System CDF control room Monitors online histograms & status of Consumers, HVs and Tevatron Beams Alerts shift-crew in case of problems -> Determines Online Good Run Status

11 DQM Offline Model for CDFLatest calibrations and alignments are used to reconstruct high-level objects (electrons,. photons, jets, J/Y...) as they are employed in final physics analyses A number of critical quantities are selected, enough for DQM diagnosis The DQM expert system implements the logic to automatically analyze the critical histograms and evaluate their quality position & width signal vs background The errors detected (either due to raw detector quantities or caused by offline reconstruction codes) are promptly reported to detector experts

12 Status of DQM Project DQM Online (maintained by 1 FTE)100% Operational in 2005 CDF shift-crew now relies on it DQM Offline (maintained by 1 FTE) Expert 100% in 2005 System fully automatic and used to validate data & offline reconstruction software New versions of “good run” lists regularly delivered to CDF

31 TeV4LHC Our Goals at ATLAS: Join the existing IFAE efforts in ATLASOUR GROUP IN CDF JOINS IFAE/ATLAS Our Goals at ATLAS: Join the existing IFAE efforts in ATLAS Bring our experience on hadron collider physics Bring our living experience on DQM and Operations

32 TeV4LHC In 2008 members of our group are being invited to participate in ATLAS preparatory meetings for LHC Physics 2 invited talks at Berkeley Workshop on Boson+jets Production (LBL, March 2008) 1 invited talk at CERN´s Workshop on MC tools for BSM Physics (CERN, March 2008) 1 invited HEP seminar at University of Chicago on SUSY searches (Chicago, April 2008) 1 invited talk at ATLAS-France Workshop on Jets (Paris, June 2008) IFAE plays a leading role in ATLAS Monte Carlo studies on Z+jets CSC note (to large extent a follow up of our PRL work in CDF) One of us acts as internal referee of ATLAS CSC note on SM background for SUSY searches Just a living example of the merging between great IFAE-ATLAS existing efforts and IFAE-CDF experience U. Blumenschein & E. Segura (IFAE-Barcelona)  Already involved in ATLAS where our Tevatron experience pays off

33 DQM at ATLAS The success of the DQM model at CDF inspired ATLAS (also CMS) to adopt very similar solutions for quality monitoring activities ATLAS Management very much welcomes our participation on the existing DQM efforts (most natural involvement in required ATLAS service work) Our group will initially focus on Tier0 DQM activities at CERN Since Fall 2007 two members of our group (M. D’Onofrio, MMP) actively participate on ATLAS DQM work & FDR activities….more by summer 2008

34 Initial Physics ProgramNo surprise that our initial physics program at the LHC will be a natural continuation of our search activities in CDF (by construction) Inclusive Jet Production and Quark Compositeness Drell-Yan and Z+jets production Search for Gluinos and Squarks Top Physics …. some of the first analyses that will be carried out at the LHC as soon as the data becomes available… We merged efforts with the rest of IFAE-ATLAS group F. Gianotti et al., Follows expected lumi profile & understanding of physics objects in ATLAS vs time

35 SUSY Searches at the LHCThe LHC is built to discover SUSY If there, we will find it relatively soon But…we do not underestimate the commissioning phase and the work needed to understand the SM backgrounds (QCD-jets, top, Boson+jets….)

36 Computing In CDF, keeping leadership on physics analysesrequired adequate CPU & storage capabilities (huge MC & data samples, NLO programs, endless SUSY scans..) We built a small cluster in BCN PIC) for CDF physics analyses

37 BCN DCAF @ PIC Production CAF (Condor)1 Server CAF -> Dual Xeon 2.4 Ghz 1 Server SAM -> Dual Xeon 2.4 Ghz 120 jobs in parallel (~300 kSI2k) ~24 TB of disk space (~12 TB at FNAL) A Technician takes care of it Modest in size but plays a fundamental role in all physics analyses of the group CPU steadily increased thru years Since almost 3 years the cluster is available to ALL CDF users…heavily used Part of the hardware already 3-years old will require some replacement soon… 2-years period

38 Computing Needs for CDF/ATLASOur physics analysis power will be determined by our “real” CPU and storage capacity Replacement & slightly increase of CPU & disk space necessary for CDF BCNCAF in 2009 Tier1 and Tier2 LHC resources largely scheduled by Grid and ATLAS management Only about ~168 kSI2k from Tier2 devoted to physics analysis by (~430 kSI2k by 2011) assuming 50% of the resources assigned to IFAE  as reported on March 08 Tier2 review  clearly insufficient (see CDF numbers) We need a rather modest but highly available cluster for our ATLAS analyses (Tier3 like) Analysis of data/MC root files Generation of small Monte Carlo samples Scan on parameter space (SUSY, etc..) NLO and NNLO heavy calculations Investment/resources optimized by gradually redefining “CDF nodes” into “ATLAS nodes” (of course, we implemented same technology) BCNCAF as seed for our Tier3 cluster

39 Budget

40 Notes on Budget ( ) We present a 3-years project to continue/complete our physics program in CDF and initiate an energetic activity on ATLAS together with the rest of the IFAE Group Essential to ensure the continuation of financial support for PostDocs on CDF/ATLAS to fulfill our commitments (we need at the very least to maintain the manpower level) Our physics analysis model relies on a steady increase of the available computing capabilities and an early definition of a Tier3-like cluster (consistent with increasing Tevatron luminosity and the arrival of the first ATLAS data in 2009) Our commitments and leadership on the physics analyses require a constant presence of manpower at Laboratories
