HEPLike: An open source framework for experimental likelihood evaluation

Abstract

We present a computer framework to store and evaluate likelihoods coming from High Energy Physics experiments. Due to its flexibility it can be interfaced with existing fitting codes and allows to uniform the interpretation of the experimental results among users. The code is provided with large open database, which contains the experimental measurements. The code is of use for users who perform phenomenological studies, global fits or experimental averages. Program summaryProgram Title: HEPLikeProgram Files doi:http://dx.doi.org/10.17632/4wvfyp7zyt.1Licensing provisions: GPLv3Programming language: C++Nature of problem: Provide a uniform way of store, share and evaluate experimental likelihoods in a proper statistical manner. The code can be easily interfaced with existing global fitting codes. In addition a large database with the measurements is published. The program targets users who perform in their scientific work: phenomenological studies, global fits or measurements averages. The HEPLike has been created for FlavBit project [1], which was used to perform several analysis [2,3] and here we present an updated version, which can be used in standalone mode.Solution method: C++ code that evaluates the statistical properties of the measurements without user intervention. The large open database is provided as well. The measurements are stored in YAML files allowing for easy readability and extensions. ReferencesarXiv:1705.07933arXiv:1705.07935arXiv:1705.07917
