    611[[br]]An equivalent file exist for [ MadWeight] : [  MadWeight Update Notes]:  
    9 === News === 
    10    * 26-June-2009 [[br]] MadEvent is now compatible with the LHAPDF module. So that you can run MadEvent with your favorite set of PDF. 
    11    In the same time, we introduce a new routine: ./bin/ in order to select  gfortran in order to compile your directory. 
    13    * 11-May-2009 [[br]] New subversion of [ MadWeight] (now in subversion 2.2) See [  MadWeight Update Notes] for more information. 
    15    * 21-Dec-2008 [[br]]A bug has been recently discovered that might have affected xsec calculation and event generation starting from the second run in a given process directory if particular cuts (pt,...) have been lowered in run_card.dat after a first integration, or if the PDF/collider params have been changed. In many cases, ME forced the grid reset, but not systematically. [[br]] 
    17    * 6-Dec-2008 [[br]] [ MadOnia] is out   and available. [[br]] 
    19    * 01-Dec-2008 [[br]] First beta version of USRMOD version 2, compatible with FeynRules models and now completely generic, is available. Contact [wiki:MichelHerquet Michel] for more info and help testing it. [[br]] 
    21    * 17-Aug-2008 [[br]] [ MadDipole] is out ([ arXiv:0808.2128])  and available. [[br]] 
    23    * 06-Aug-2008 [[br]] [ MadWeight] is out and available. For any decay chain and user-defined transfer functions, [ MadWeight] compute automatically the weights used in the matrix element method. [[br]] 
    25    * 10-Jul-2008 [[br]] MadGraph/MadEvent passed to version 4.3, including a new Grid run mode and a large number of new standard cuts[[br]] 
    27    * 07-Jul-2008 [[br]] New HELAS routines by Hagiwara et al.  for spin two particles included in the HELAS release,  [ arXiv:0805.2554] [[br]] 
    29    * 26-Jun-2008 [[br]]FeynRules is officially out, [ arXiv:0806.4194][[br]] 
    31    * 5-Feb-2008 [[br]]Grid beta version installed on the development cluster. New cuts included! [[br]] 
    33    * 17-Dec-2007 [[br]] MadGraph version for calculation of quarkonium amplitudes in NRQCD available (on request). [[br]] 
    35    * 11-Dec-2007 [[br]]Version 4.2 including decay chains (beta) is now out and available on all clusters! [[br]] 
    37    * 08-Dec-2007 [[br]] A bug was discovered and fixed which affected the downloaded MG/ME package version 4.1.45-46 (on the UCL cluster 22 Nov - 8 Dec). If you downloaded one of these files, please download a new version (4.1.47 or later). Note that web generation was not affected.[[br]] 
    39    * 01-Dec-2007 [[br]] The Roma cluster is available again after hardware fixing [[br]] 
    41    * 07-Nov-2007 [[br]] MadGraph/MadEvent now acts also as an automatic width calculator and decay event generator (from version 4.1.45).[[br]] 
    43    * 01-Oct-2007 [[br]] Around 1400 registered users. [[br]] 
    45    * 10-Aug-2007 [[br]] Major improvements in the generation efficiency.  Resonance intermediate information passed to the events improved (now always compatible with color information).[[br]] 
    47    * 15-Jun-2007 [[br]] MG/ME v4 paper is out: [ arXiv:0706.2334][[br]] 
    49    * 01-Apr-2007 [[br]] Version 4.1 including Matrix element/Parton shower jet matching a la MLM (using cone or kT jets) available from the web. [[br]] 
    51    * 15-Mar-2007 [[br]] The MadGraph/MadEvent Wiki page up and running! [[br]] 
    53    * 01-Mar-2007 [[br]] New functionalities added to the results web page. The full generation chain can be performed one step at the time. [[br]] 
    55    * 23-Feb-2007 [[br]]An error was introduced in version 4.1.16-17 (Feb 2-9) which drastically degraded the efficiency of unweighting. If you generated a process or downloaded code between those dates, please regenerate the process/download a new version.[[br]] 
    57    * 16-Feb-2007 [[br]] Version 4 available on all the MadGraph severs/clusters.[[br]] 
    59    * 9-Feb-2007 [[br]]  New standalone version of MadGraph available. This is the current official version of the original program which is mostly meant for "theorists". Given a model and a (multi-)process, MadGraph Standalone creates the corresponding code for the matrix element squared. The resulting file is easily exportable to other codes, since the dependencies are kept to a minimum. The only libraries needed are for HELAS (libdhelas3.a) and for the MODEL (libmodel.a). These are automatically built and available in the libraries directory (lib). Parameters of the model are passed in a standardized format (LesHouchesII-like) through the param_card.dat. A sample program, check , that generates random points in phase space and returns the corresponding value of the matrix element is provided. Detailed instructions can be found in the README file. [[br]] 
    61    * 19-Dec-2006: [[br]]      Improved structure of the simulation chain (MadGraph -> Pythia -> PGS): [[br]]    Events are available as:  parton-level (Les Houches event file format), hadron-level, after showering and hadronization done in Pythia (stdhep), reconstructed objects after detector simulation (PGS4), with the new LHC Olympics format. Events at the three levels are also available as root files. Events can be traced from one stage to the other, since numbering is kept consistent along the simulation chain. A series of standard plots is provided at each step. [[br]] 
    63    * 18-Dec-2006 [[br]] MadGraph Les Houches events are interfaced to the CMSSW framework. Thanks to [ Dorian Kcira]. More info and examples on the [ Wiki CMS page].[[br]] 
    65    * 22-May-2006[[br]] Version 4.0 ready! Highlights: [[br]] 
    66       1. The full code (including the web interface) is now managed under CVS and can be exported easily to other clusters. 
    67       1. Automatic event generation from the web up to PGS events. 
    68       1. New models available: MSSM, 2HDM, HEFT,... 
    69       1. Setting up new models has been made easy. USRMOD is a framework where to implement new models. All the "fortran" work is taken care by a Perl script. The user only provides Feynman rules and relations between primary parameters and those appearing in the Feynman rules. 
    70       1. New card system. From the process generation to the events in PGS. Model parameters are given by a LH friendly file.  
    71       1. Calculators for generating LH cards available for the SM, MSSM, 2HDM. 
    73    * 16-Feb-2006 [[br]] [ TwoHiggsCalc], The new Two Higgs Doublets Model Parameter Calculator, compliant with the SLHA format, has been released. [[br]]   
    75    * 21-Dic-2005 [[br]] [ SMadGraph], the Supersymmetric version of MadGraph, has been released! Implementation into MadEvent coming soon..! [[br]]   
    77    * 21-Dic-2005  [[br]] New [ interface] to Pythia by Johan Alwall.[[br]] 
    79    * 18-Nov-2005 [[br]] Number of registered users >500 .[[br]] 
    81    * 16-Nov-2005 [[br]] Minimal User Guide updated.[[br]] 
    83    * 29-Oct-2005 [[br]] System upgrade and migration to new disk completed.  New MadAnalysis to Root by [ Marco Zanetti] (CMS, Padova-Italy) implemented on the web.  MadGraph Les-Houches-compliant event files are imported to Root and a tree is created (rootfile) that  can be dowloaded from the results page.  It contains '''all''' the information (including the banner) of the original ASCII data file,  plus a simple set of plots which can be used for further analysis.[[br]] 
    85    * 08-Aug-2005:  [[br]]  New plotting routines implemented. A simple set of plots is automatically generated at the end of  the run and showed on the results page.  Jets and identical particles are automatically ordered in pt.[[br]] 
    87    * 01-Aug-2005[[br]]  Database beta version in place. Administrator web page functional. Banner upload functional: event sets can be exactly reproduced on the web.[[br]] 
    89    * 25-Jun-2005:[[br]]  New web version available. Major improvements in the perl scripts and web generation of events.  Banner improved: all the information about a run is contained in the input-card.dat that is stored  on top of the event file (banner). Handling of multiparticles schemes made automatic.[[br]]
