1 CMS Software and Physic project at HIP V. Karimäki Project evaluation meeting CERN, May 22, 2006

2 22 May 2006CMS Software and Physics 2 Outline ● Our mission ● Project members ● Members' special talents ● Physics simulation overview ● Electron/gamma overview ● Geant4 work ● Track based alignment of tracker elements ● Grid computing ● Test beam work ● Plans and future challenges

3 Our mission Physics simulation Detector simulation Developing reconstruction algorithms Preparation for physics analysis, discovery potentials Developing calibration algorithms, particularly track based alignment and ECAL energy calibration Test beam on-line + off-line software and analysis To take care of our share of CMS computing challenge Calibration and analysis of forthcoming real data! 22 May 2006 CMS Software and Physics 3

4 22 May 2006CMS Software and Physics 4 Project members in CMS Veikko Karimäki, PhD physicist1990- Ritva Kinnunen, PhDphysicist1990- Kati Lassila-Perini, PhDphysicist1994- Sami Lehti, PhDphysicist1997- Tomas Linden, PhDphysicist1997- Aatos Heikkinen, PhD stud physicist1996- Tapio Lampen, PhD stud physicist1997- Jukka Nysten, PhD stud physicist2000- Lauri Wendland, PhD stud physicist1999- In addition 2-4 Summer Trainees at CERN every year Typical carrier path for young members: 1) CERN summer trainee 2) diploma on particle physics 3) PhD studies in the project We are all physicists eager to continue our work with real data next year after a very long period of preparations!

5 22 May 2006 CMS Software and Physics 5 Project members Aatos, Geant4, expert of hadronic processes Sami, physics simulation& analysis talent Tomas, computing specialist, grid, clusters Tapio, expert in alignment with tracks i Ritva, physics simulation& analysis talent Le Lauri, DAQ expert H->  specialist Kati, CMS User Support Coordinator, electron rec. Jukka N, e/  detection, tracker/ecal beam tests Jukka K, GRID computing, former project member

6 22 May 2006CMS Software and Physics 6 Physics simulation studies People involved: Ritva, Sami, Kati, Lauri, Aatos, Jukka, VK MSSM H ->  H ± ->  discovery potentials (Ritva, Sami, Lauri)  jet tagging for HLT and off-line (Lauri) Tagging b jets with NN approach (Aatos, Sami) Methods to enhance signal to background CMKIN maintenance, kinematics generators interface (VK) Extensive contributions to the CMS PTDR Vols 1-2 Active reporting in conferences Referee work, thesis opponent (Ritva) PhD thesis work (Lauri)

7 22 May 2006CMS Software and Physics 7 Electron/photon physics & reconstr. Kati, Jukka N. tracker/ECAL reconstruction photon conversions in tracker ECAL test beam activities energy calibration algorithms Kati now a User Support Coordinator PhD thesis work (Jukka)

8 22 May 2006CMS Software and Physics 8 Geant4 activities Aatos (also Tapio contributed earlier) Aatos member of Geant4 Steering Board Jorma member of the Geant4 Oversight Board Aatos co-coordinator of the Geant4 hadronic processes nuclear evaporation model implemented (Tapio) intranuclear cascade model implemented (Aatos) production runs (Aatos, Tomas) extensive students education activities (CERN & Helsinki) organization of ”Finnish Geant4 symposia” (2002, 2005) refereeing of Geant4 related papers in IEEE (Aatos) acquired expertise is beneficial also for CMS work!

9 22 May 2006CMS Software and Physics 9 Track based alignment Now Tapio and VK (earlier Aatos, Tomas,...) Long term work and learning process Challenging mathematical formulations Innovation: H.I.P. algorithm (proved successful) Contributions to PTDR Vol 1 Active reporting in conferences (Tapio) PhD thesis work (Tapio) Alignment can be crucial for new discoveries!

10 22 May 2006CMS Software and Physics 10 Grid computing at HIP Tomas, HIP grid coordinator Designed and built Mill cluster at campus site Ametisti cluster, part of M-grid of Finnish universities Active participation in NDGF meetings Several co-operation parties: –Finnish IT Scientific Centre –HIP technology program –Dept of Physical Sciences Aiming at Tier 2 services for LHC experiments in Finland Tier 1 for Nordic countries – a common effort Funding request several MEUR – growing optimism

11 22 May 2006CMS Software and Physics 11 Test beam work Co-operation with the HIP tracker project Helsinki Silicon Beam Telescope (SiBT) Off-line analysis of test beam data (Tapio) Data acquisition code (Lauri) Developed alignment ideas Also involved in radiation hardness studies Very fruitful collaboration with tracker project!

12 22 May 2006CMS Software and Physics 12 Publications –Despite CMS is not a running experiment, the group has been active in publishing, especially CMS Notes, Analysis Notes, Internal Notes and contribution to TDR’s: total about 90 publications since the change of millenium –Also refereed articles in scientific journals and conferences: total about 75 publications since the change of millenium

13 22 May 2006CMS Software and Physics 13 Conference and workshop organizations The project members have organized a number of symposia and workshops: –CERN School of Computing, Aug 21-Sep 1, 2006, Helsinki –2 nd Nordic Grid Neighbourhood Conference, Otaniemi, – 2.6., 2006 –2 nd Finnish Geant Workshop, Helsinki, 6-7 June, 2005 –1 st Finnish Geant Workshop, Helsinki, 2003 –The 3 rd Nordugrid Workshop, May, 2002 – Workshop on b / tau Physics at the LHC, , 2002

14 22 May 2006 CMS Software and Physics 14 Plans and future challenges 1 year goal (until the start of data taking mid 2007): active tuning of the experiment software + documentation active involvement in optimizing the alignment strategies active involvement in designing the analysis strategies collaboration with the HIP tracker project (test beam) long term (data taking and running the experiment): need all (and even more) manpower to: maintain + improve software with real data gradually improve the software alignment control the quality of data do competitive physics analysis
