2. 2Winfried A. MitaroffSept. 21, 2009 Mission statement To coordinate and further the experimental activities aiming at our participation in an experiment (ILD) at a “TeV scale” e – e + Linear Collider (the ILC). Project Group formally inaugurated in January 2006, but software and hardware activities started already in 2003 and 2004, respectively. Work done in close collaboration with the Institute’s Depts. of “Algorithms & Software Development” (ASE) and “Semiconductor Detectors” (HLD). Activities trying to achieve maximal synergy with the Institute’s Project Groups “CMS” and “BELLE”.

5. 5Winfried A. MitaroffSept. 21, 2009 Motivation for the ILC With the start of LHC, we are entering a new era of science: exploring the “TeV scale” physics. Profound discoveries are expected at energies around 1 TeV. To mention just two of them: – Precision measurements up to 200 GeV at LEP (collected 1989 - 2000) predict to find the origin of the “electroweak symmetry breaking” (Higgs mechanism ?). – Astrophysics has established the existence of “dark matter” in the universe; theories beyond the Standard Model, known as “supersymmetry”, predict candidates. These discoveries will require further investigations which proton-proton collisions can only partly provide (because of being composed particles).

7. 7Winfried A. MitaroffSept. 21, 2009 The International Linear Collider (ILC) – Collision energy adjustable for scans in the range 200 – 500 GeV, stability and precision of the beam energies to be below 0.1 %; – The machine must be upgradable to a collision energy of 1 TeV; – Peak luminosity of ≈ 2×10 34 cm -2 s -1, with an integrated luminosity of 500 fb -1 to be achieved within the first 4 years of operation; – Electron polarization at least 80%, positron polarization an option; – Options: Z factory (“GigaZ”), e – e –, e – γ, γγ (“photon collider”). The ILC basic design is a worldwide consent since autumn 2004; Technology is based on superconducting RF cavities at 1.3 GHz, average field gradient is 31.5 MV/m in the first (500 GeV) stage; The project is pursued by the “Global Design Effort” since 2005. Beam crossing angle 14 mrad, only 1 experimental zone with 2 detectors operating in “push/pull”.

8. 8Winfried A. MitaroffSept. 21, 2009 ILC detector concepts SiD = “Silicon Detector” (USA) LDC = “Large Detector Concept” (Europe) \ ILD = “Int. Large Detector” GLD = “Gaseous Large Detector” (Japan) / (Europe + Japan) 4th = “4 th Detector Concept” (Europe + USA) Cross-concept “horizontal” detector component R&D collaborations: SiLC = “Silicon for Linear Colliders”, LCIO = common data model, etc. etc. HEPHY has opted for the ILD concept !

9. 9Winfried A. MitaroffSept. 21, 2009 The ILD detector concept Central tracking detector: large TPC – excellent pattern recognition in a dense track environment, – proven technology; Silicon tracker: pixels and ss/ds strips – extended tracking coverage, – improved track momentum resolution; High-precision Si vertex detector – close (16 mm) to the beam interaction point, – best possible heavy flavour tagging; Fine-granularity calorimeters – “particle flow calorimetry” is our asset, – provides necessary jet energy resolution; Solenoid magnetic field of 3.5 T – upgradable to 4 T (for the ILC 1 TeV stage); Almost 4π geometric acceptance – to the benefit of tracking & calorimetry. Basic design parameters fixed 2008: August 2009: our LoI was “validated” by IDAG, the decision endorsed by ILCSC !

Moser: presented at the 5 th ECFA “ILC Workshop”, Warsaw, June 2008)

23. 23Winfried A. MitaroffSept. 21, 2009 Challenge: fwd. track reconstruction Present status: – ILD track reconstruction in the forward region (a MarlinReco module) is in bad shape: legacy FORTRAN 77 code, wrapped in C++, … – Thus, a background study in the forward region is missing in our LoI; – Problem had been postponed so far, but will become urgent soon. Our proposal: – Take responsibility of ILD track reconstruction in the forward region: develop a new MarlinReco module from scratch at HEPHY Vienna; – Need to keep contact with track reconstruction in the barrel region, detector description database, TPC and SiLC detectors, and more; – Project to be done in close cooperation with Dept. ASE, and building upon our expertise gained from DELPHI, CMS, and the LDT. – Extra manpower required: 2 undergraduate or 1 graduate student(s). Timescale: – Module should be ready for the “Interim Report”, due by mid 2010; – In addition, strive for leading the background study in the fwd. region. This will be a significant contribution to the ILD concept, and a chance to strengthen our position in this collaboration.

27. 27Winfried A. MitaroffSept. 21, 2009 Conclusions The ILC is designed to perform precision measurements of electron-positron collisions up to 1 TeV, in order to – firmly establish the nature of the discoveries made at LHC; – gain a deeper understanding of their behaviour; – search for new phenomena which cannot be found at LHC; – give hints to physics far above the TeV scale (GUT ?). The ILC project is based on a world-wide consent in the community, pursued by the “Global Design Effort”, and supported in Europe, North America and East Asia. – However, a decision for its realization can only be made after relevant physics results from LHC (by 2012 ?). – At HEPHY, a small but highly motivated group of physicists is engaged in the ILD Detector Concept, thus contributing to this next big challenge of experimental particle physics.

34. 34Winfried A. MitaroffSept. 21, 2009 LDT – main features The “LiC Detector Toy” (LDT) is a simple, powerful program tool for detector design studies. It aims at investigating track resolutions for optimizing the layout (geometries and material budgets). The Detector model corresponds to a collider experiment with solenoid magnet. The geometry is cylinder symmetric w.r.t. beam axis z, but not necessarily w.r.t. the z = 0 plane. Surfaces are either cylinders (“barrel”), or planes (“forward/backward region”). The track model is a helix. Supports tracking from the barrel into the forward/backward region, and vice versa (re-entry). Simulation takes into account multiple scattering, detector inefficiencies and measurement errors, but no other degredation. Only single tracks are processed, there is no pattern recognition ! Track reconstruction is performed by a Kalman filter, with the reference surface being the inside of the beam tube. Goodness-of-fit tests are standard. Supported detectors are Si pixels, Si strips (single- or double-sided with any stereo angle), and a TPC. Detector description defined by a simple “input sheet”. An interactive GUI is available. The program is written in MatLab (a language and IDE by MathWorks). The latest version 2.0 is also available for GNU Octave, albeit without the GUI. A beta release is available on request. For more information, please, consult the web at http://wwwhephy.oeaw.ac.at/p3w/ilc/lictoy/LDTsource_20.zip (source code), http://wwwhephy.oeaw.ac.at/p3w/ilc/lictoy/UserGuide_20.pdf (User’s Guide). http://wwwhephy.oeaw.ac.at/p3w/ilc/lictoy/LDTsource_20.zip http://wwwhephy.oeaw.ac.at/p3w/ilc/lictoy/UserGuide_20.pdf Recent improvement: simulation of energy loss of electrons by bremsstrahlung (Bethe-Heitler); the corresponding reconstruction by a Gaussian Sum Filter (GSF) is not yet implemented. Pending: support of azimuthal segmentation; a cylindrical drift chamber (CDC) in place of TPC.

35. 35Winfried A. MitaroffSept. 21, 2009 RAVE / VERTIGO – main features Creation of an extensible, detector-independent toolkit (RAVE) for vertex reconstruction, to be embedded into various environments: – RAVE = “Reconstruction (of vertices) in abstract versatile environments”. – The toolkit includes both vertex finding (a pattern recognition task a.k.a. track bundling) and vertex fitting (estimation of the vertex parameters and error matrix); – Synergy used: starting point was the old CMS software (ORCA) which has been refactored and ported to the new CMS framework (CMSSW); – Principle algorithmic assets are robustified reconstruction methods, with estimators based on adaptive filters, thus downweighting the influence of outlier tracks; – Recent improvements: vertex fitting with kinematic constraints; implementation of a Gaussian Sum Filter (GSF) for electron tracks reconstructed with e-loss by bremsstrahlung; – RAVE is foreseen to stay source-code compatible with CMSSW, but thanks to its generic API may easily be embedded into other software environments. Creation of a simple standalone framework (VERTIGO) for fast implemen- tation, debugging and analyzing of the core algorithms: – VERTIGO = “Vertex reconstruction tools and interfaces to generic objects”. – Framework tools available: Visualization, Histogramming, a “Vertex Gun” for generating test events, an LCIO input event generator, and a “Data Harvester & Seeder” for flexible I/O; – VERTIGO is able to emulate various detector setups by a flexible “skin” concept.

36. 36Winfried A. MitaroffSept. 21, 2009 RAVE / VERTIGO – status Present status: – Code is C++; RAVE depends on CLHEP and Boost, VERTIGO’s visualization also on Coin3d; – Tested with Linux (Debian, SL4), Mac OSX and Windows (VisualStudio), on Intel and PPC; – RAVE may be called directly from C++, and with a wrapper (SWIG) also from Java and Python; – Adaptor classes (“glue code”) exist for embedding RAVE into the reconstruction frameworks Marlin (C++) and org.lcsim (Java); tested with LDC/ILD and SiD full simulation data; – RAVE has been successfully embedded into 4th’s ILCroot (C++) framework by INFN Lecce; – Simple VERTIGO skins exist for the LDC/ILD and SiD; tested with LCIO formatted input data. Recent features: – Interface with the ZvTop topological vertex search algorithm (developed by RAL, UK); – Inclusion of the beam spot in a primary vertex fit, and re-fitting the tracks by a smoother step; – Implementation of a simple “heavy flavour tagging”, kinematics fitting, and a GSF. Availability: – The Vienna ILC Project Group is committed to maintenance, documentation and distribution; – A beta release is available, and can be downloaded from the web: http://project.hepforge.org/rave/ (repository for RAVE source code, docus, etc); http://stop.itp.tuwien.ac.at/websvn/ (repository for glue code and VERTIGO); – RAVE’s installation support is for the GNU build system (Autotools); glue code is supported by CMake when required by the environment (e.g. for MarlinRave).http://project.hepforge.org/rave/http://stop.itp.tuwien.ac.at/websvn/
