DØ Run II SUGRA Working Group

The DØ Run II SUGRA Working Group is a part of the Fermilab-wide Run II SUSY/Higgs Working Group. We are working on the many tasks necessary to assure the greatest possible sensitivity for supersymmetry searches at DØ. Supersymmetry models are frequently classified by the mechanism by which the breaking of supersymmetry is achieved. In supergravity (SUGRA) models, the mechanism is gravity. We are working on models based on minimal low-energy supergravity — the "mainstream" of supersymmetry models.

For information about the DØ Run II SUGRA Working Group, please contact Eric Flattum, the coordinator of this group.

You can also send mail directly to all members of the SUGRA working group, via the mailing list d0-sugra@fnal.gov. To join this mailing list, send a message to Eric Flattum or Marc Paterno.

You never know what you might find.

Meeting Minutes

• Minutes of the May 13th meeting
• Minutes of the May 20th meeting

Monte Carlo

• Pythia rcp files for the three SUGRA points are located in:
• /projects/703/new_2/run2/sugra/pythia/RUNFILES/pythia_0_100_200_3_-1.rcp
• /projects/703/new_2/run2/sugra/pythia/RUNFILES/pythia_0_500_150_3_-1.rcp
• /projects/703/new_2/run2/sugra/pythia/RUNFILES/pythia_0_500_200_35_-1.rcp

where the order of the parameters in the filename is A0, m0, m1/2, tan(beta), and sgn(mu). The rcp files are no longer called directly by the version of Pythia created by John Hobbs but they are used to produce two files (*.cards and *.run) which effectively do the same thing. See tools on how to run Pythia.

Odds and Ends

• SUGRA summary at the SUSY/Higgs Workshop on May 15 by Teruki Kamon
• A brief report on MSSM conventions written by V. Barger and Chung Kao can be found here. The formula in this report will generate the same mass spectrum for charginos, neutralinos, and sfermions as the output of ISAJET.
