5. Parked data During RUn1 we have promptly reconstructed ~500 Hz of data and parked almost an equivalent amount for later reconstruction ( when CPU resources would be available) : this processing has been done during the Long shutdown period. At present > 20 analysis have profited of this additional statistics 5

9. Run2 readiness In short: all subsystems, DAQ, dataflow, reconstruction software ready Have been in global data taking 24/7 for the last 8 weeks accumulating cosmic rays with and without field for alignment, synchronization and calibration This has followed 10 periods of 3 days global running started in June which progressively validated the commissioning of the new DAQ, Timing and Control distribution, the changes in the detector setups and more … 9

10. Korean contribution at the RPC project Korean Institutions are giving a great contribution to the RPC projects since many years. They are working on both hardware and software tasks and many students are working very well with us. Korea University built was one of the main actor in the RE4 upgrade. They built 600 gaps of bakelite RPC. 10 chambers have been assembled and tested at CERN by the SKK University group and are now running in CMS Web Based Monitoring tool is an Institutional responsibility of the Korea University. SKK has many responsibilities in the DPG (data quality, software release validation and DQM)

11. Software and Computing Commissioning of Higher Level Trigger Farm for Production Move to multi-core queues at CERN and Tier-1s Refactoring Tier-0 for Distributed Prompt Reconstruction and use of Agile Infrastructure Improvements in Data Access and AAA Improvements in Data Management and Dynamic Data Placement Improvements in Distributed Analysis (CRAB3) Work towards Opportunistic Computing (HLT now routinely used ‘opportunistically’ for offline tasks) Major progress: reco CPU Multithreading now standard

12. CMS Tier1 in Korea We support the creation of Tier1 in Korea at KISTI and we hope that we will keep moving in this direction: it would establish the Korean CMS community as a key CMS team in ASIA. It is not by chance that we plan to have the future CMS DataAnalysisSchool in Korea 12

13. 13 Physics preparations for Run 2 Two major ‘timed’ exercises: CompSoftAnalysis-challenge14 (2 months in summer): focus on validation of new software framework, new miniAOD and validation of Physics Object reconstruction with 25 ns bunch spacing and higher Pileup at 13 TeV PHYS14 (2 months in fall) : end to end ‘run’ on High Priority Analysis for first 1-5 fb -1 at 13 TeV 1B events for startup (reconstructed twice: for 50ns and for 25 ns) PYTHIA8 samples already produced (~1/3 of overall budget) LO & NLO generators validated with 8 TeV data 1B events for startup (reconstructed twice: for 50ns and for 25 ns) PYTHIA8 samples already produced (~1/3 of overall budget) LO & NLO generators validated with 8 TeV data Monte Carlo production

17. Executive Summary Technical Proposal to be submitted to June LHCC Trackers upgrades well defined: extended pixelated coverage in fwd region to  =4 Trigger: Track-Trigger at Level 1 baseline, basic parameters to cope with peak Lumi at 7.5 10 34 Hz/cm 2 Defined Calorimeter: – barrel electronics consolidation defined – Forward Calo: choice between two technologies will happen next week – Muons: first Upgrade ( GEM station to consolidate trigger and redundancy in critical forward region) TDR presented at March LHCC. Upgrade of barrel Electronics and improved forward robustness/rate capability defined 17

18. Muons 18 Improvements of existing detectors Electronics: DT minicrates, CSC inner MEx/1 readout needed for trigger upgrade Forward 1.6 < |η| < 2.4 upgrades L1 trigger rate reduction, enhanced redundancy GEMs: GE1/1 and GE2/1 iRPCs: RE3/1 and RE4/1 operation in higher rate Very forward extension muon tagging ME0 with GEMs 6 layer stub baseline 2.0 < |η| < 3.0 TDR presented to LHCC

19. https://twiki.cern.ch/twiki/bin/view/MPGD/CmsGEMCollaboration GE1/1 19 GE1/1: precision chambers to guarantee high performance during late Phase I (LS2 installation) and throughout Phase II:  improve L1 and HLT muon momentum resolution, to reduce or maintain global muon trigger rate  restore redundancy GEM TDR:  upgrade high 

20. 20 X3 reduction Forward trigger for |  |>1.6 relies entirely on the CSC system: Measurement driven by internal chambers: least scattering, strong B field. GEM detector in front of CSC can measure muon bending angle in magnetic field and add redundancy maintain 15 GeV online threshold, keep < 5 kHz rate, high efficiency Lever arm - trigger Why GE1/1 helps so much?

26. A warm thank’you We would like to thank all of you, as well as the Korean Ministry you represent, for the long-standing and sustained support of the CMS experiment. It is thanks to this support that the Korean team in CMS is able to pursue its excellent research program. Support for travel will be very important now that we restart data taking and operations 26

27. Summary We have ‘emerged’ successfully from the Long shutdown with an improved detector, acquisition, trigger and Software We are looking forward to an exciting Run2 at 13TeV We are finalizing out Upgrade plans for the HighLuminosity LHC 27
