simulation at ILC

[Dr.]

Hi Colleauges,

I'm simulating a rare Higgs production at parton level at the e+e- collider with Madgraph. But I found the invariant mass distribution of 2 b-jets shows a very sharp peak at the exact 125 GeV. I thought the reason may be no smearing effect included in the parton level events. It seems we should pass the events through delphes. Is there an available delphes card for the ILC? Thank you very much!

Cheers

Lei

Hi Lei,

there is no ILC card in Delphes. However, you can find a very preliminary card for TLEP in the pre-release 3.0.13pre1:

You should first have the ROOT software installed.

Then download the file, untar it and install Delphes by typing:

wget http://cp3.irmp.ucl.ac.be/downloads/Delphes-3.0.13.pre1.tar.gz
tar xzvf Delphes-3.0.13.pre1.tar.gz
cd Delphes-3.0.13
make

If you have generated a file "file.hep" with MadGraph, in order to produce an output with delphes:

./DelphesSTDHEP examples/delphes_card_TLEP.tcl delphes_output.root file.hep

Please be aware that this card is a dummy example and is not tuned to the performance of existing detectors.

Hi Michele,

Thank you very much! It is really helpful! Currently a simple TLEP card is enough for my study. But a e+e- Higgs factory is warmly discussed. So if Delphes team can develop a card aiming for such study, that will be very useful and be appreciated!

Cheers
