z-hisggs preliminary results (2)
Efficiencies:
z-higgs preliminary results
Here are some plots produced using the muon selection from Hajrah to tag the muons in the PandoraPFOs collection.
Additional cuts: momentum of the lepton from Z greater than 20 GeV; mass of the Z boson between 70 and 110 GeV.
Recoil mass reconstructed using the nominal centre of mass energy.
The black and the red lines on the plots correspond to Ecm = 230 GeV and Ecm = 250 GeV, respectively. The samples used are described here.

Efficiency Plots with more statistics
After applying the Muon cuts, the efficiency plots for Momentum and Costheta are shown below.

Edinburgh z-higgs samples
Edinburgh Z-higgs samples, e+e- -> Z h
Z -> mu+ mu-
h -> anything
The samples are located on the GRID at
/grid/ilc/users/edinburgh/data/z-higgs
Up to now there are 2 samples,
- Ecm = 230 GeV,
- Ecm = 250 GeV,
with 20000 events each. Both reconstructed (still being uploaded) and DST files are available.
More details can be found here.

Sample grid locations
I've copied most of my samples to the grid, and started a script running to copy the rest. Everything is under the directory:
With currently three directories:
The files should be self descriptive from the filename. I was going to write how many events etcetera there are here but I've rather stupidly left my log book at home, and I'm away from tonight. There are only 10000 WW events (in 2 files), other than that everything should be whatever the numbers are for 500 fb^-1. Higgs to bbbar is split over 4 files, and the ZZ stuff is split over 100 files.
The detector is LDC01_05Sc at 250GeV, but with SEcal03 instead of SEcal02 (there was a problem with SEcal02, I can't remember the details). Beam effects were simulated by forcing the centre of mass energy in Pythia to match the energy spectrum from PandoraPythia (with the 500GeV beam parameters). That's about all I can remember for now, I'll check my log book when I get back.

Installing OpenScientist
OpenScientist is a full C++ implementation of AIDA. I was having big problems using Java on 64 bit machines reliably so switched to this instead of AIDAJNI.
To install, first download from openscientist.lal.in2p3.fr. I went for the "batch" version, which is basically the simple version without any GUI stuff for batch processing.
The installation instructions weren't particularly to the point so I'll recap what I did briefly (obviously change the version number if appropriate):
I think that builds everything (there is more to OpenScientist than just an AIDA implementation), but it's easier than figuring out which bits you actually need.
To use it with the lcio software you need a CMake module. I wrote one with all the library and include directories hard coded into it; it would be nice if I wrote a proper self-detecting one but I haven't had the time. You can find out the compiler flags for AIDA with the utility "<location>/OpenScientist/v16r4/osc_batch/v16r4/bin_obuild/osc_batch/v16r4/bin/aida-config".
My module is here, obviously you'll need to change the directories to match your system. I called the module FindBatchLab.cmake, so then all you have to do is put that module in with the other CMake modules and change the dependencies in your projects CMakeLists.txt file from "AIDAJNI" to "BatchLab".
IMPORTANT NOTE FOR JAS USERS - BatchLab puts empty histograms/clouds etcetera into the AIDA file, which JAS doesn't like (e.g. if you create a histogram and didn't fill it with anything). I modified the file "OpenScientist/v16r4/BatchLab/v1r2p1/source/XML/XML_DataWriter.cxx" to this. Copy my file over the original before building if you want to use JAS to analyse your AIDA files. The xml schema says there should be at least one entry for clouds/histograms/etc, so I think the JAS way is the correct way.

Minutes of Meeting 30/6/08
Present: Hajrah, Roberval, Victoria, Mark, Joel (Clare is still in a muddy field)
θ
- Mark's samples for 500 fb-1 of ZH at 250 GeV (mh = 120 GeV, Z->ee) have finished running through simulation and he is checking them. He used LDC01_05sc. The samples will be made accessible on the Grid and a post made to this blog. Z->µµ samples can also be made.
- Clare has been working on getting a working suite of software on the Bristol 64-bit machine (Roberval has successfully compiled the new version of MARLIN on the Edinburgh machine in 32-bit mode)
- Roberval has been writing a processor to use the muon ID cuts to tag RPOs
- Hajrah is looking at electron and muon cut ID efficiency as a function of θ and momentum, but needs bigger samples
- Victoria only has a few more weeks before her leave commences
- Mark has been encountering problems reading in large (~10 GByte) LCIO files. No-one knows of any physical limit, but he will split the files up in future.
