Parked data • During RUn 1 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

Run 2 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

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 RE 4 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)

Software and Computing • Commissioning of Higher Level Trigger Farm for Production • Move to multi-core queues at CERN and Tier-1 s • 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 (CRAB 3) • Work towards Opportunistic Computing (HLT now routinely used ‘opportunistically’ for offline tasks) Major progress: reco CPU Multithreading now standard

CMS Tier 1 in Korea • We support the creation of Tier 1 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 Data. Analysis. School in Korea 12

Physics preparations for Run 2 Two major ‘timed’ exercises: • Comp. Soft. Analysis-challenge 14 (2 months in summer): focus on validation of new software framework, new mini. AOD and validation of Physics Object reconstruction with 25 ns bunch spacing and higher Pileup at 13 Te. V • PHYS 14 (2 months in fall) : end to end ‘run’ on High Priority Analysis for first 1 -5 fb-1 at 13 Te. V Monte Carlo production 1 B events for startup (reconstructed twice: for 50 ns and for 25 ns) PYTHIA 8 samples already produced (~1/3 of overall budget) LO & NLO generators validated with 8 Te.

Phase 2 upgrade 16

Executive Summary • Technical Proposal to be submitted to June LHCC • Trackers upgrades well defined: extended pixelated coverage in fwd region to h=4 • Trigger: Track-Trigger at Level 1 baseline, basic parameters to cope with peak Lumi at 7. 5 1034 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

Muons Improvements of existing detectors Electronics: DT minicrates, CSC inner MEx/1 readout needed for trigger upgrade Forward 1. 6 < |η| < 2. 4 upgrades L 1 trigger rate reduction, enhanced redundancy GEMs: GE 1/1 and GE 2/1 i. RPCs: RE 3/1 and RE 4/1 operation in higher rate Very forward extension muon tagging ME 0 with GEMs 6 layer stub baseline 2. 0 < |η| < 3. 0 TDR presented to LHCC 18

GEM TDR: m upgrade high h GE 1/1: precision chambers to guarantee high performance during late Phase I (LS 2 installation) and throughout Phase II: Ø improve L 1 and HLT muon momentum resolution, to reduce or maintain global muon trigger rate Ø restore redundancy GE 1/1 https: //twiki. cern. ch/twiki/bin/view/MPGD/Cms. GEMCollaboration 19

Why GE 1/1 helps so much? Forward trigger for |h|>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 Lever arm trigger X 3 reduction maintain 15 Ge. V online threshold, keep < 5 k. Hz 20 rate, high efficiency

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

Summary • We have ‘emerged’ successfully from the Long shutdown with an improved detector, acquisition, trigger and Software • We are looking forward to an exciting Run 2 at 13 Te. V • We are finalizing out Upgrade plans for the High. Luminosity LHC 27
