PYTHIA: 

pythia6206.pdf:  the whole thing
ATHENA-PYTHIA Interface: Pythia variables to be set in the jobOptions.txt file under // GENERATOR SETUP
 Examples of PYTHIA production/decay codes set: click on “DCO”(earlier runs) or ”DC1” (later runs, hence more accurate); the ATHENA-PYTHIA Interface above lists the allowed variable combinations (see Table 3,4 in the PYTHIA manual above); it is useful to read sections 3.5 and 3.6 in the PYTHIA manual on the use of these variables; the PYTHIA variables for the main Standard Model production the Higgs Boson with subsequent decay into 4 e or 4 muons are listed here and described in the PYTHIA manul on pages 35,36; the PYTHIA variables for the Standard Model production the Top Quark with unbiased decays  are listed here and described in the PYTHIA manul on page 35;
Monte Carlo Particle Numbering Scheme: go to the complete table at the end
Pythia Decay Codes: e.g. g->e e = 170; Z->e e = 182

ATLAS ANALYSIS:

A Recent ATLAS analysis of H-> 4 muons:  From Athens , May 2003, the most advanced analysis so far - a good place to peek when doing our H-> 4 e analysis (a MS Powerpoint file).
A Collection of Useful Grafs (Powerpoint, collected from the Athens May 2003 talks and …)

DATA SETS:

The Data Challenge 1 (DC1) CBNT ntuples for data validation: seem to have been made with ATRECON, not ATHENA reconstruction!!
How to use the Combined Ntuple: click “list variables” and get a description of the variables that can be in the ntuple. The ntuples for H->4e, 4mu and 2e2mu will be available on the BNL High Performance Storage System (HPSS). Once they are, a description of how to access them will be posted here. The size of the files you get here when clicking the dataset number, e.g. 001002 for H-> 4 e.
Alexander Khodinovs full Simulation DC1 production:
you access these via rftp:
NOTE! underlying event from multiple interactions NOT turned on in PYTHIA (Moustapha)
rftp>cd ~khodinov/simul/data/000032: 130 GeV h->4e, 100 k events, 300 events (=~200 MB)/file, 33 files
rftp>cd ~khodinov/simul/data/000033: 130 GeV h->4e,4mu,2e 2mu, 100 k events, 300 events(=~200MB)/file, 33 files
rftp>cd ~khodinov/simul/data/000035:   ttbar for Ketevi (consult him re Pythia parameters , mu only ? ask Ketevi)
this is our dominant background for h-> 4l's (for whichever lepton l Ketevi asked for)
info on the simulation runs can be found in the DC1 production data base maintained by Alexander Khodinov and Pavel Nevski:

this database is only accessible to the 2 persons above. Relevant copies of dataset, eventgeneration, full simulation filter and geomeytry tables

open questions: vertex smearing, get copies of PYTHIA joboptions files from Moustafa
