It's based on John Conway's PGS 3 after considerable hacking by Steve Mrenna for the LHC olympics last winter. John Conway released a significantly improved new version this summer, with some bug fixes, code cleanup , and a trigger table, but the only jet algorithm he implemented was kT jets, which are supposed to be great for QCD but in hard scattering events they don't reconstruct the partons they came from as well as cone jets. … text/html 2009-10-07T17:20:27-04:00 http://marmoset.jthaler.net/wiki/doku.php?id=executables&rev=1254950427&do=diff Note, Marmoset1/bin should be added to your $PATH. For the most part, all executables should be run from a runDir directory. See the help files on workflow to learn how to perform an OSET analysis and use the exec in practice.

The core functionality of fitOSET_C is written in c++. *OVERVIEW* fitOSET_C fits the parameters of an OSET to a monte carlo by minimizing a chi-squared-like variable whose “bins” are the counts in each signature. The signature counts of the monte carlo are referred to as the targetvector. fitOSET_C performs the minimization from several different s… text/html 2008-05-28T22:54:11-04:00 http://marmoset.jthaler.net/wiki/doku.php?id=installing&rev=1212029651&do=diff There are currently two somewhat different installation options for Marmoset, depending on how you want to use it. * If you want to interface with PGS, you probably want to follow the ORIGINAL MODE instructions. These installation instructions also download Pythia 6, STDHEP, two versions of PGS, and a private root-based plotting tool (see description of dependencies below) * If you only want to generate STDHEP or Les Houches format events in Marmoset, and want to download less code, ple… text/html 2007-11-18T21:12:48-04:00 http://marmoset.jthaler.net/wiki/doku.php?id=marmoset&rev=1195438368&do=diff Mass And Rate Modeling in On-Shell Effective Theories Marmoset is a strategy and a set of tools for characterizing and fitting physics beyond the Standard Model in a model-independent scheme. We introduce the idea of On-Shell Effective Theories (OSETs), which provide a flexible framework in which to describe new physics in terms of just the masses, production modes, and decay modes of candidate new particles. OSETs are well-suited for Monte Carlo-based analysis and interpretation of new physics… text/html 2007-03-06T20:40:05-04:00 http://marmoset.jthaler.net/wiki/doku.php?id=matrix_elements&rev=1173231605&do=diff Currently, Marmoset can only handle 2->1 (Breit-Wigner), 2->2 (in a power series in X and ξ), and limited2->3 hard scattering matrix elements. It is possible for the user to hard code new matrix elements as needed.

How will we reconstruct the fundamental theory of the electroweak scale from LHC data?

There is a osets/par subdirectory that can store pythia card files, but it is not currently in use. All OSET files must end with .oset. When you run parseOSET, .oset files are converted to meta files that store all of the information necessary to generate monte carlo and match rates.
