TILC08 meeting Sendai

TILC08 meeting (Sendai)

• Plenary talks in the opening session
• Comments from ICFA (Albrecht Wagner)
• Message from ALCSC (Won Namkung)
• Japanese Roadmap (Atsuto Suzuki)
• ILC and Future Particle Physics and Cosmology
  (Hitoshi Murayama)
• ILC accelerator (Barry Barish)
• Experimental Overview (Sakue Yamada)
• As other recent workshops, this was a joint
  meeting of the GDE and the regional
• (in this case ACFA) ILC community
• Several satellite meetings GDE EC, FCAL coll,
  LCTPC coll, SiLC, ILD
• First Asian (regional) workshop that had strong
  international attendance
• ( 50 from the other regions)

LoIs, collaboration across frameworks concepts

• International Detector Advisory Group (IDAG) now
  formed S. Yamadas talk, p4
• Recent change to LoI process (S. Yamada) rather
  than choosing 2 LoIs, it is
• planned that LoIs will be validated by IDAG
  in order to have more cooperation
• than competition among the LoI groups (exact
  validation procedure still to be decided)
• In the physics simulation / reconstruction area,
  Norman Graf and Akiya Miyamoto
• emphasised the need to collaborate across the
  software frameworks
• encouraging developments are underway, with
  strong involvement from the UK
• Satoru Uozumi showed first results from using
  PandoraPFA and LCFI Vertex with
• input from Jupiter full MC, using new
  LCIO-based interfaces to/from Asian framework
• Marcel Stanitzki presented PFA performance
  comparisons for SiD-ish detector
• Tomas Lastovicka showed physics results from US
  MC Marlin-based reconstruction

Diagnostic Histograms

• Diagnostic plots of event data
• MCParticles, hits, clusters
• Runs on different detectors
• must have compact description
• also need sampling fractions
• Easy to use and setup
• on the web at
• http//lcsim.org/SlicDiagWeb/
• SLAC CVS project
• cvs d pserveranonymous _at_cvs.freehep.org/cvs/l
  cd co SlicDiagnostics
• ./build.sh
• ./bin/SlicDiagnostics ...

SiD Global Parameter Optimization Using PandoraPFA

• SiDish detector using Mokka/Marlin framework
• Preliminary results of Z pole events ( uds only )
  
• Plan to do study higher energy jets, different
  segmentation, etc.

Summary
Tomas Lastovicka

• LCFI vertex package is a mature software package
  used in ILD and SiD detector concepts.
• Its application to 6-jet ZHH (SiD) events looks
  very promising
• existing results on Higgs self-coupling may be
  improved.
• It is used in sbottom analysis indirectly (so
  far)
• Very challenging due to softness of these
  events
• There are more analysis within the LCFI
  collaboration under way I have not covered in
  this talk (e.g. tt, stau).

Thank you for attention

Positive response to LCFI physics work

• Akiya Miyamoto in his summary of the simulation
  session mentioned the
• recent progress in the reconstruction area
  and concluded that these
• software efforts will play a central role in
  the coming detector optimisation
• and benchmark studies.
• Akiya also pointed out that LCFI Vertex is the
  standard vertexing package
• Also Norman Graf in his talk on PFA,
  Reconstruction and Benchmarking
• listed the LCFI code as one of the tools used
  for benchmarking the SiD detector

Satellite ILD meeting

• SLAC SM background samples generated using
  Whizard now close to final,
• most problems understood, test production to
  start soon
• New ILCSoft reference installation
  /afs/desy.de/group/it/ilcsoft/v01-03-02 tagged
• shortly before the workshop, available on the
  GRID (LCG grids supporting VO ilc)
• Example how to use this installation on the GRID
  and a list of sites where this is
• currently available shown by Frank Gaede
  (p16)
• Detector geometry to be frozen this week,
  followed by full chain software test
