General Info

ATLAS collaboration publications related with SUSY searches can be found here:

https://twiki.cern.ch/twiki/bin/view/AtlasPublic/SusyPublicResults

Backgrounds Generation Strategy

The backgrounds generation follow Table 2 of:

http://cdsweb.cern.ch/record/1191916/files/ATL-PHYS-PUB-2009-084.pdf

in terms of MC event generators. For the detector simulations PGS4 is used instead ALTFAST.

The setups for the MC generators, events filtering, detector simulations, etc ... used by the ATLAS collaboration can be found in:

http://alxr.usatlas.bnl.gov/lxr/source/atlas/

To be as close as possible to the ATLAS collaboration simulations via ATHENA the following paper:

http://iopscience.iop.org/1742-6596/219/3/032001

The interfaces used by ATHENA to the MC generators can be found in:

http://alxr.usatlas.bnl.gov/lxr/source/atlas/Generators. For each generator there is a suffix "_i" and usually

in the src folder there is a C++ code with it. For instance, the one related with HERWIG is called Herwig.cxx

and it's located in the Herwig_i/src folder. Thus, all the main files used match with the interfaces used by

ATHENA.

We follow the specific inputs used by the collaboration as labelled by MC10 located in:

http://alxr.usatlas.bnl.gov/lxr/source/atlas/Generators/MC10JobOptions


t tbar

The setup for the MC generators is tagged as MC10*** for the ATLAS collaboration.

We use the MCatNLO code for computing the matrix elements for the ttbar production at NLO.

The hadronization follows JIMMY . Tau decays are treated via TAUOLA and photon decays via PHOTOS.

As mentioned above we use PGS4 for simulating the ATLAS detector.

My Personal Preferences

  • Show tool-tip topic info on mouse-over of WikiWord links, on or off:
    • Set LINKTOOLTIPINFO = off

  • More preferences TWiki has system wide preferences settings defined in TWikiPreferences. You can customize preferences settings to your needs: To overload a system setting, (1) do a "raw view" on TWikiPreferences, (2) copy a Set VARIABLE = value bullet, (3) do a "raw edit" of your user profile page, (4) add the bullet to the bullet list above, and (5) customize the value as needed. Make sure the settings render as real bullets (in "raw edit", a bullet requires 3 or 6 spaces before the asterisk).
