Several desirable extensions were discussed, some of which are essential. Data types There is a need to end the assumption that all data are in the form of histograms (with x/y axes). Non-histogram data which needs to be stored include: anonymous@undisclosed.example.com (Anonymous) 2013:groups:tools Thu, 06 Jun 2013 17:46:00 +0000 https://phystev.cnrs.fr/wiki/2013:groups:tools:hepmc?rev=1371630034&do=diff Proposed updates for HepMC event record GenRun There is a need to store the names and version numbers of all generators used in producing an event. Propose to define a GenRun object to contain cross section (GenCrossSection) and other run-level quantities discussed below. Each GenEvent should link to the GenRun. anonymous@undisclosed.example.com (Anonymous) 2013:groups:tools Wed, 19 Jun 2013 10:20:34 +0000 https://phystev.cnrs.fr/wiki/2013:groups:tools:lhef?rev=1370612944&do=diff Update of LHE file format We intend to have a discussion on extensions of the Les Houches event file format, gearing towards an update which merges proposed and de facto in use extensions of the standard in a coherent way.

At the Les Houches workshop in 2009 an update was suggested, mainly to improve the handling of NLO and matching/merging.

This project tries to evaluate various substructure techniques and configurations with respect to their effectiveness in the suppression of pile-up for given observables, and the enhancement of signal-to-background ratios.$ \sqrt{s… anonymous@undisclosed.example.com (Anonymous) 2013:groups:tools Fri, 07 Jun 2013 15:46:16 +0000
