From laura at projects.hepforge.org Thu Jan 18 15:39:58 2018 From: laura at projects.hepforge.org (laura at projects.hepforge.org) Date: Thu, 18 Jan 2018 15:39:58 +0000 Subject: [Laura-announce] New version (v3r4) of Laura++ package released Message-ID: <5a60bfce.OfuKpT3xJzXJ8kAS%laura@projects.hepforge.org> Dear Laura++ users, We are very pleased to announce the release of v3r4 of the Laura++ package. One major change introduced in this version is a change of the software licence under which the package is released. All previous versions were released under the terms of the Boost Software License, Version 1.0, which can be found at the following URL: http://www.boost.org/LICENSE_1_0.txt >From v3r4 forward we are releasing the package under the terms of the Apache License, Version 2.0, which can be found at the following URL: http://www.apache.org/licenses/LICENSE-2.0 This version also contains the following changes: * Correct LauFlatteRes to use the exact formulae from the papers that report the default parameter values for each supported resonance - Correct behaviour in the cases where the m0 is absorbed into the couplings - Use the correct value of g1 for the a_0(980) (needed to be squared) - Set also the mass values to those reported in those papers - Added printout to specify what is being done in each case * Improve the consistency between the weightEvents functions in LauSimpleFitModel and LauCPFitModel - Remove the unecessary division by ASqMax in LauIsobarDynamics::getEventWeight - Improve error messages in LauCPFitModel::weightEvents * Allow background yields to be specified as any LauAbsRValue, i.e. can now be specified as a LauFormulaPar * In LauFitDataTree::readExperimentData add a check that the tree contains the branch "iExpt" and if not: - If the requested experiment is 0 then read all data in the tree (and print a warning) - Otherwise print an error message and return Please see the doc/release.notes file for a full record of the changes. The new version can be downloaded from the download page: http://www.hepforge.org/downloads/laura or checked out from svn. The doxygen documentation is available on the webpage: http://laura.hepforge.org/doc/doxygen/v3r4/ A new version of the paper draft will also be posted to arXiv shortly to reflect these few changes. This version will also be submitted to the journal. Many thanks, The Laura++ Developers From T.Latham at warwick.ac.uk Sun Jun 17 21:46:15 2018 From: T.Latham at warwick.ac.uk (Latham, Thomas) Date: Sun, 17 Jun 2018 20:46:15 +0000 Subject: [Laura-announce] Laura++ paper published in Computer Physics Communications Message-ID: Dear Laura++ users, We are very pleased to announce that the paper ?Laura++ : a Dalitz plot fitter? has been published in Computer Physics Communications 231 (2018) 198-242. The paper is available open access under the CC-BY-4.0 licence from the journal: https://doi.org/10.1016/j.cpc.2018.04.017 The version on arXiv has also been updated: https://arxiv.org/abs/1711.09854 The paper precisely documents the formalisms, conventions and methodologies employed to model the signal and background distributions in the Dalitz plot, including the effects of efficiency and resolution. The sections on the implementation of each of these components include some suggestions on best practice. There are then sections on the workflows used to generate toy MC, fit data samples and weight simulated samples, including some of the variations available, the performance of the package and some potential future developments. There are also a number of appendices that give further details on the formalisms and other features available. The published version of the paper documents the state of the code as of v3r4, i.e. the current release. We hope that it will serve as a useful reference for anyone using the package, whether just starting out or an experienced user.
