| 8 | === Aim of the project === |
| 9 | |
| 10 | Produce a database of validated LHC parton-level (and possibly hadron-level) MC |
| 11 | events with MadGraph and the corresponding codes for large scale production. |
| 12 | Main SM backgrounds and signals should be included, as well as representative BSM samples. |
| 13 | |
| 14 | === Motivation === |
| 15 | |
| 16 | MC's samples will play a fundamental role in the path to making discoveries at the LHC. |
| 17 | Latest generation of the MC's have improved on several important aspects: from |
| 18 | a more accurate simulation of events with multi-jet final states (with ME/PS matching) |
| 19 | to full flexibility on new physics models implementation. |
| 20 | |
| 21 | The increasein the MC powers is paralleled by the larger complexity of the codes |
| 22 | both at the computational and user level, leading to the need of |
| 23 | a continuous and reliable support from the MC developers. Normally, many issues |
| 24 | arise in the dey-to-day use of such codes, some of which become essential |
| 25 | in the final experimental analyses. |
| 26 | |
| 27 | We propose to provide samples and codes for key SM and BSM processes at the LHC. |
| 28 | |
| 29 | For 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 | |
| 34 | The samples and the associated codes would be therefore validated by |
| 35 | the MC authors and directly used by experimentalists or as a reference |
| 36 | (comparison) with dedicated analysis generations. |
| 37 | |
| 38 | A public set of samples to be used as a common '''reference''' by all the |
| 39 | LHC community (exp and th) could be very useful for other reasons. |
| 40 | For instance, they could form a base for future comparisons between |
| 41 | experiments or make the interactions with theorists (both model builders and |
| 42 | MC 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 | |
| 61 | We 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 | |
| 71 | Matching validation will be performed with MatchChecker. |
| 72 | |
| 73 | ==== Definition of the most important samples ==== |
| 74 | |
| 75 | A 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 | |
| 82 | Information 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 | |
| 147 | Please 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. |

| 402 | Reference 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! |
