Projects:

Generators Infrastructure:

Study and fix the event record at the Fortran (HEPEVT) level using the hepevt_repair program (Contact: C. Biscarat)
Update Tauola library. Update Tauola interface with Tauola author's interface. Expand to all 22 decay channels (Contact: C. Biscarat)
Review and improve the particle selection in MC++ including additional tests using the particle status (Contact: S. Muanza, S. Protopopescu)
Develop a framework executable for Alpgen (Contact: S. Muanza, C. Biscarat. High Priority)
Interface PHOTOS to Pythia and Herwig in a consistent way (Contact: S. Muanza, G. Brooijmans)
Test the Multiple Parton Interaction in Herwig v6.505 using the Jimmy v4.1 package (p14.09.00, p17) (Contact: S. Muanza)
Finalyze the FOME metadata; have them introduced in SAM and d0runjob and test them; get rid of the current generator specific metadata (Contact: S. Muanza, ongoing)
Introduce the FOME MD in Alpgen script or MCalpgen.x, mc@nlo, CompHep,... (Contact: S. Muanza)
Test EvtGen C/B-hadron decays in Herwig (p14.09.00) (Contact: S. Muanza)
Introduce an optional use of the PDFLIB and the LHAPDF in single generators executables (MCpythia.x, MCherwig.x,...) (Contact: S. Muanza, P. Telford, H. Schellman)
Introduce an optional use of the ISAJET and SUSPECT SUSY RGEs in susy_tools (Contact: S. Muanza)
Update PROSPINO to v2 (Contact: S. Muanza)
Systematize the usage of the SUSY LHA in susy_tools (Contact: S. Muanza)
Introduce and systematize the usage of HDECAY and SDECAY for Higgs and SUSY MC samples. Include these tools in susy_tools (Contact: S. Muanza)
Improve and update the documentation

Using CD Generators DB MC Samples:

Copy the samples from ENSTORE, process them using a custom MCstdhep.x, write the generator file metadata, store the generated file in SAM, define a SAM dataset, submit a MC Request for processing at the MC farms (Contact: S. Muanza, ongoing, help needed )
Improvment: also write a FOME MD and declare the MCFIO file in SAM

Generators Certification:

Review and fix the problems with generators parameters and metadata in mc_runjob/d0runjob. Discuss thhe implementation and test with the d0runjob team. An alternative is to develop a Cardfiles DB (Contact: S. Muanza, C. Biscarat, G. Brooijmans)
Improve and systematize the usage of the Cardfiles_Tester.sh (Contact: S. Muanza)
Revive and improve the mctest package (Contact: J. Rani)

Generators Usage:

PDF usage and PDF uncertainties: (Contact: S. Muanza, T. Nunnemann)
Fragmentation systematic uncertainties: study and provide a general procedure to measure the systematic uncertainty related to the fragmentation model used in our MC samples. The 2 reference models are the Lund fragmentation implemented in Pythia and the cluster fragmentation implemented in Herwig ran with the Jimmy package to simulate MPI (Contact: S. Muanza )
Matrix Element and Parton Shower matching: implement the Mangano's matching prescription at D0. Provide tools to apply it on the Alpgen+Pythia (and more generally on FOME+PS) MC production at D0 (Contact: M. Begel, S. Muanza, ongoing, help needed)
Merging of Alpgen+Pythia DSPACK files in the Common Alpgen Production Script (Contact: C. Biscarat, ongoing, testing needed)

Generators Informations in MC Samples:

Maintain the MC Catalog, develop the "step 3" for automated samples search (Contact: S. Muanza, C. Biscarat)
Send feed-back on bugs and problems to this central Catalog (All users!!!)
