     3== MadGraph Samples for LHC physics ==
     4
     5
     6
     7
     8=== Aim of the project  ===
     9
     10Produce a database of validated LHC parton-level (and possibly hadron-level) MC
     11events with MadGraph and the corresponding codes for large scale production.
     12Main SM backgrounds and signals should be included,  as well as representative BSM samples.
     13
     14=== Motivation ===
     15
     16MC's samples will play a fundamental role in the path to making discoveries at the LHC.
     17Latest generation of the MC's have improved on several important aspects: from
     18a more accurate simulation of events with multi-jet final states (with ME/PS matching)
     19to full flexibility on new physics models implementation.
     20
     21The increasein the MC powers is paralleled by the larger complexity of the codes
     22both at the computational and user level, leading to the need of
     23a continuous and reliable support from the MC developers. Normally, many issues
     24arise in the dey-to-day use of such codes, some of which become essential
     25in the final experimental analyses.
     26
     27We propose to provide samples and codes for key SM and BSM processes at the LHC.
     28
     29For each process we plan to publish: 
     30
     31   1. Small-size (<1M) parton-level and hadron level (Pythia) sample.
     32   1. Associated (frozen) code for large scale production over the grid.
     33
     34The samples and the associated codes would be therefore validated by
     35the MC authors and directly used by experimentalists or as a reference
     36(comparison) with dedicated analysis generations.
     37
     38A public set of samples to be used as a common '''reference''' by all the
     39LHC community (exp and th) could  be very useful for other reasons.
     40For instance, they could form a base for future comparisons between
     41experiments or make  the interactions with theorists (both model builders and
     42MC developers) easier.
     43
     44=== People ===
     45
     46   1. MadGraph Team (including Steve Mrenna)
     47   1. Roberto Chierici & Paolo Bartalini (CMS)
     48   1. Interested: Jon Butterworth & Osamu Jinnouch (ATLAS)
     49
     50=== Tools ===
     51   
     52   * MadGraph/ MadEvent v4 :
     53      * SM
     54      * BSM (SUSY, topBSM, 2HDM, UED,...)
     55      * ME/PS matching within Pythia
     56   * GridDevelopment: How to use the grid packs
     57   * [https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/MatchChecker MatchChecker]
     58
     59=== Modus Operandi ===
     60
     61We have identified three phases:
     62
     63   1. Agreement on the definition of the most important samples (all)
     64      * List of processes
     65      * Trigger or acceptance cuts
     66      * SM Parameters
     67      * Benchmark points and models for BSM
     68   2. MC codes and samples generation and validation   (mg team + anybody interested)
     69   3. Large scale samples generation with (full) detector simulation (CMS+ATLAS)
     70
     71Matching validation will be performed with MatchChecker.
     72 
     73==== Definition of the most important samples ====
     74
     75A sample is defined by specifying:
     76
     77   * Model
     78   * Initial state and final state particles
     79   * Couplings (EW, and QCD)
     80   * Phase space region
     81
     82Information for MG/ME generation is collected in the banner through which a the sample can be fully reproduced.
     83
     84===== SM parameters =====
     85
     86   * Masses -> latest best values. LO parameters for EW.
     87   * PDF set and alphaS  : cteq?
     88   * Scales: for matched samples these are automatically set by the code.
     89

     145=== Some LHE files and cards used for validation ===
     146
     147Please note that these files need to be passed through the Pythia package found on the MG/ME download page. For all jet multiplicities below the highest multiplicity wanted, IEXCFILE=1 must be specified in the pythia_card.dat. For the highest multiplicity wanted, IEXCFILE=0 must be specified.

     388Notes
     389   * xqcut used: 10 GeV -> Qcut=15 GeV to be used in pythia_card.dat
     390   * for all multiplicities EXCEPT the highest, use IEXCFILE=1

     394==== Other notes ====
     395For the pythia step treatement the following parameter could be usefull:
     396
     397   * MSTP(81)=0 !use virtuality-ordered showers
     398   * MSTP(5)=109 ! tune to use the Underlying Events for PDF CTEQ6L1

     400==== Typical run time ====
     401
     402Reference machine is a recent macbook running Leopard, intel CPU 2.16 GHz Dual Core 2 (but only one CPU is used of course), 4Mb of L2 cache and 1Go of RAM. The process is (W+>e+ve)+jets at the LHC, with all parameters and cuts set to their default values. The warming up time is for a rather slow 24*1GHz cluster (FYNU cluster at UCL). The compiled gridpack sizes are for static linking only, dynamic linking should decrease them a lot. Also, the run time is not expected to scale linearly with the number of [http://www.essaywriter.co.uk/services.aspx essay] diagrams, in particular for complicated processes. Generating 10K W+2j events could take only 2h, not 12h!
