== MadGraph Samples for LHC physics == === Aim of the project === Produce a database of validated LHC parton-level (and possibly hadron-level) MC events with MadGraph and the corresponding codes for large scale production. Main SM backgrounds and signals should be included, as well as representative BSM samples. === Motivation === MC's samples will play a fundamental role in the path to making discoveries at the LHC. Latest generation of the MC's have improved on several important aspects: from a more accurate simulation of events with multi-jet final states (with ME/PS matching) to full flexibility on new physics models implementation. The increasein the MC powers is paralleled by the larger complexity of the codes both at the computational and user level, leading to the need of a continuous and reliable support from the MC developers. Normally, many issues arise in the dey-to-day use of such codes, some of which become essential in the final experimental analyses. We propose to provide samples and codes for key SM and BSM processes at the LHC. For each process we plan to publish: 1. Small-size (<1M) parton-level and hadron level (Pythia) sample. 1. Associated (frozen) code for large scale production over the grid. The samples and the associated codes would be therefore validated by the MC authors and directly used by experimentalists or as a reference (comparison) with dedicated analysis generations. A public set of samples to be used as a common '''reference''' by all the LHC community (exp and th) could be very useful for other reasons. For instance, they could form a base for future comparisons between experiments or make the interactions with theorists (both model builders and MC developers) easier. === People === 1. MadGraph Team (including Steve Mrenna) 1. Roberto Chierici & Paolo Bartalini (CMS) 1. Interested: Jon Butterworth & Osamu Jinnouch (ATLAS) === Tools === * MadGraph/ MadEvent v4 : * SM * BSM (SUSY, topBSM, 2HDM, UED,...) * ME/PS matching within Pythia * GridDevelopment: How to use the grid packs * [https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/MatchChecker MatchChecker] === Modus Operandi === We have identified three phases: 1. Agreement on the definition of the most important samples (all) * List of processes * Trigger or acceptance cuts * SM Parameters * Benchmark points and models for BSM 2. MC codes and samples generation and validation (mg team + anybody interested) 3. Large scale samples generation with (full) detector simulation (CMS+ATLAS) Matching validation will be performed with MatchChecker. ==== Definition of the most important samples ==== A sample is defined by specifying: * Model * Initial state and final state particles * Couplings (EW, and QCD) * Phase space region Information for MG/ME generation is collected in the banner through which a the sample can be fully reproduced. ===== SM parameters ===== * Masses -> latest best values. LO parameters for EW. * PDF set and alphaS : cteq? * Scales: for matched samples these are automatically set by the code. ===== Standard Model Samples ===== || QCD Jets || || '''Process''' || '''Stars''' || '''Couplings''' || '''Binning''' || '''Phase space region''' || '''Matching''' || '''Event files''' || '''Remarks''' || || ''' jets (2)''' || 3. || QCD only || HT bins (100-250 !GeV, 250-500 !GeV, 500-1000 !GeV, 1000-inf !GeV) || abs(eta(j))<5, Ptj>20 !GeV || 0,1,2,3,4+ || || light jets are u,d,c,s,b,g; Need to veto the first gluon splitting into bb in the PS || || ''' bb~ + jets ''' || 3. || QCD only || HT bins (100-250 !GeV, 250-500 !GeV, 500-1000 !GeV, 1000-inf !GeV) || abs(eta(j))<5, Ptj>20 !GeV || 0,1,2,3+ || || massive b; Need to veto the first gluon splitting into bb in the PS || || ''' bb~ bb~+ jets ''' || 1. || QCD only || none || || 0,1+ || || massive b || || Vector Boson || || '''Process''' || ''' Stars ''' || '''Couplings''' || '''Binning''' || '''Phase space region''' || '''Matching''' || '''Event files''' || '''Remarks''' || || '''W (-> l v)+ jets ''' || 3 || EW=2 + QCD || none || all || 0,1,2,3,4+ || || W=W+,W- ; l=(e,mu,tau) || || '''Z /a (-> l+l-)+ jets ''' || 3 || EW=2 + QCD || none || m(l+l-)>50 !GeV || 0,1,2,3,4+ || || photon is included ; l=(e,mu,tau) || || '''Z /a (-> l+l-)+ jets ''' || 3 || EW=2 + QCD || none || 50>m(l+l-)>10 !GeV, HT>30 !GeV || 0,1,2,3,4+ || || photon is included ; l=(e,mu,tau) || || '''Z (-> vv)+ jets ''' || 3 || EW=2 + QCD || none || pt(Z)>50 !GeV || 0,1,2,3,4+ || || || || '''V (-> l l')+ QQ~ ''' || 1 || EW=2+QCD || none || all || no || || V=W+,W-,Z ; l=(e,mu,tau,v), (Z->vv included) Q=b, c || || ''' a + jets ''' || 3 || EW=1 + QCD || HT bins (40-100 !GeV, 100-200 !GeV, 200-inf !GeV) || pt(a)>20 !GeV, abs(eta(a))<2.5, !DeltaR(a,jet)>0.3 || 0,1,2,3,4+ || || || || ''' a + QQ~ + jets ''' || 1 || EW=1 + QCD || none || pt(a)>20 !GeV, abs(eta(a))<2.5, !DeltaR(a,jet)>0.3 || 0,1,2+ || || photon; Q=b || || Vector Bosons || || '''Process''' || '''Stars''' || '''Couplings''' || '''Binning''' || '''Phase space region''' || '''Matching''' || '''Event files''' || '''Remarks''' || || '''VV(-> 4l)+ jets''' || 3 || EW=2+QCD || none || m(l+l-)>10 !GeV; m(lv)>30 !GeV || 0,1+ || || V=W+,W-,Z l=(e,mu,tau,v) || || '''VV (-> 4l) + QQ~ ''' || 1 || EW=1 + QCD || none || all || no || || V=W+,W-,Z l=(e,mu,tau,v), Q=b || || '''aV(-> 2l)+ jets''' || 1 || EW=2+QCD || none || pt(a)>20 !GeV, !DeltaR(a,jet)>0.3 || 0,1+ || || V=W+,W-,Z l=(e,mu,tau,v) || || ''' a a + jets''' || 1 || EW=2+QCD || none || pt(a)>20 !GeV, abs(eta(a))<2.5, !DeltaR(a,jet)>0.3 || 0,1,2+ || || photon || || ''' a a + QQ~ + jets ''' || 1 || EW=1 + QCD || none || pt(a)>20 !GeV, abs(eta(a))<2.5, !DeltaR(a,jet)>0.3 || no || || photon; Q=b || || '''V V V ''' || 3 || EW=3 || none || all || no || || V=W+,W-,Z || || '''a a a ''' || 3 || EW=3 || none || pt(a)>20 !GeV, abs(eta(a))<2.5, !DeltaR(a,jet)>0.3 || no || || || || Top || || '''Process''' || ''' Stars ''' || '''Couplings''' || '''Binning''' || '''Phase space region''' || '''Matching''' || '''Event files''' || '''Remarks''' || ||''' tt + jets ' || 3 || QCD only || none || all || 0,1,2,3+ || || top decays into everything.
