You will be asked to log in with your CERN account. If you don't have a CERN account, please fill [[https://account.cern.ch/account/Externals/RegisterAccount.aspx|this form]] to create a lightweight account.// Goal: Prepare an SLHA-like easy to read and write accord for describing the flow of an LHC analysis. First proposal made for a generic structure. CM and MA authors will try to implement a single lepton stop search. Proposal by Daniel Schmeier & Jamie Tattersall [[2015:groups:tools:lhaad:proposal1]] Proposal by Nishita Desai, Suchita Kulkarni & Devdatta Majumder [[2015:groups:tools:lhaad:proposal2]] Combined Proposal by ND, SK, DM, DS & JT: [[2015:groups:tools:lhaad:proposal]] Combined Proposal from Grenoble 02'16: [[2015:groups:tools:lhaad:proposalGrenoble]] Proposal to use HEPDATA format for the experiment data section. HEPDATA (https://hepdata.net/) format has recently changed, both old and new formats are text file. New format: https://github.com/HEPData/hepdata-submission (Old format: http://hepdata.cedar.ac.uk/submittingdata , see "simple input file"). Agreements: * Binned information should have a simple way to cut it * Cuts must not branch but instead can use a common 'predecessor' * Syntax must not contain brackets to allow for an easy parsing * ... To Be Discussed Isues: * Format * Definition of 'detector constructed' objects like jets, electrons, etc * How to enforce documentation of the used objects * How to enforce documentation of validation material * ... Suggestion: * Acronym: LHADA (Les Houches Analysis Description Accord) and not LHAAD * Information about benchmark points * Information about process generation needs to be added (merging parameters, generated process, link SLHA file if needed, link to model files etc.)
