CMS is a high-energy physics experiment at the Large Hadron Collider (LHC) at CERN. It is a general-purpose detector that is designed to observe any new physics phenomena that the LHC might reveal. CMS acts as a giant, high-speed camera, taking 3D “photographs” of particle collisions from all directions up to 40 million times each second. The CMS collects few tens of Peta-Bytes of data each year and processes them through Worldwide LHC Computing Grid infrastructure around the globe.

The CernVM-File System (CVMFS) is a global, read-only POSIX file system that provides the universal namespace /cvmfs. It is based on content-addressable storage, Merkle trees, and HTTP data transport. CernVM-FS provides a mission critical infrastructure to small and large HEP collaborations.

Ganga is a computational task-management tool, which allows for the specification, submission, bookkeeping and post-processing of computational tasks on a wide set of distributed resources. Ganga has been developed to solve a problem increasingly common in scientific projects, which is that researchers must regularly switch between different processing systems, each with its own command set, to complete their computational tasks. Ganga provides a homogeneous environment for processing data on heterogeneous resources.

HFLAV representatives incorporate the latest results in particle physics as they are published. Measurements of the same, or related, quantities by different experiments are combined using a statistically-robust procedure, to provide a community-resource for particle physicists to refer to when planning or interpreting their measurements. Averages are published every two years, though the web-portal is of greater importance in day-to-day work. The averaging is often Python-based.

LHCb is one of four major experiments at the Large HAdron Collider at CERN. Its purpose is to investigate the CP violations and to understand why there is matter in the World. This highly- customized spectrometer is used in the physics research beyond the Standard Model with high-precision measurements of particles produced in high-energy proton-proton collisions. Its current upgrade for Run 3 is widespread and involves supdetectors, data collection systems and analysis algorithms.

MCnet is a collaboration between the developers of the major collision-event modelling tools used at the Large Hadron Collider (LHC) and beyond. These codes are so-called “MC event generators”, theoretical physics packages that evaluate and sample from quantum mechanical distributions to create simulated particle collisions. MC generators are an essential component of both modern particle physics experiments and theory, and provide a crucial bridge between those two communities. MCnet projects include both event generators themselves, and tools that connect them to both experiment and theory.

OpenForBC is a project from INFN, the public institute for Nuclear and Subnuclear Physics in Italy. It aims at developing a common software layer for effortless partitioning of modern GPUs from different vendors (NVidia, AMD, Intel) for graphical and computing applications in the open-source Linux KVM environment, paving the way for the wide adoption of this approach both in the research and in the industry fields.

Phoenix is an experiment-agnostic library for the visualisation of detector geometry and event data in a browser.

A modular scientific software framework. It provides all the functionalities needed to deal with big data processing, statistical analysis, visualisation and storage. It is mainly written in C++ but integrated with other languages such as Python and R.

RooUnfold is a powerful modular analysis tool for the unfolding (AKA “deconvolution” or “unsmearing”) of distributions.

Rucio is an open-source software framework that provides functionality to scientific collaborations to organize, manage, monitor, and access their distributed data and dataflows across heterogeneous infrastructures. Rucio was originally developed to meet the requirements of the high-energy physics experiment ATLAS, and is continuously enhanced to support diverse scientific communities.

A vectorized high-performance library usable for fast and accurate geometry computations in very complex setups.

zfit is a highly scalable and customizable likelihood model manipulation and fitting library in Python. It uses TensorFlow as its computational backend and is optimised for simple and direct manipulation of probability density functions.
