A new implementation of the ROOT framework Julia interface, ROOT.jl, has been performed. Previous implementation could not run with recent Julia releases due to the stop of support of the Cxx.jl library it was based on to interface with the ROOT C++ libraries. The new implementation is based on CxxWrap.jl and WrapIt!. CxxWrap.jl is a package to interface C++ libraries with Julia, while WrapIt!...

RootIO.jl is a package that provides a high-level abstraction for I/O to the ROOT files. It provides a streamlined interface for creating, writing, and filling ROOT TTrees. With this new package, the user can easily write all primitive types, arrays, vectors and dataframes to a TTree in a row-wise manner, without worrying about references and pointers to the objects. The package implementation...

We briefly share insights gained from implementing RNTuple Reader twice: first in Python, and then in Julia. We discuss the composability of the RNTuple type system and demonstrate how Julia's multiple dispatch feature has been effectively employed to realize this concisely.
Regarding the implementation of RNTuple Writer, we outline the current capabilities and illustrate how they support...

EDM4hep aims to establish a standard event data model for the store and exchange of event data in HEP experiments. The Julia package EDM4hep.jl is capable of generating Julia-friendly structures for the EDM4hep data model and reading event data files in ROOT format (either TTree or RNTuple) that are written by C++ programs, utilising the UnROOT.jl package. This contribution explores the...

Python and Julia are two powerful languages that are transforming data analysis in high-energy physics (HEP).
We'll start by exploring why Python remains a go-to language for data analysis, and then pivot to Julia, which is gaining recognition for its impressive speed and suitability for scientific applications.
I’ll show you how to create a dynamic workflow that combines the strengths...

Event processing frameworks are important software components of High Energy Physics (HEP) experiments, playing a critical role in building applications for HEP-specific workflows such as trigger or event reconstruction. A key aspect of these frameworks is their ability to efficiently orchestrate the parallel processing of algorithms for multiple events simultaneously. As heterogeneous setups,...

We share a status update on the histogramming package FHist.jl, which started out as a course final project but grew to be production-grade and is used in real ATLAS analysis.
We briefly go over the feature and performance of FHist.jl, including the core features as seen in ROOT's TH* classes, as well as axillary features such as integration with Plots.jl and Makie.jl.
Finally, we...

In High Energy Physics, very demanding algorithms are written to represent the physics that takes place either in the accelerators or in the detectors and to analyze the measured signals. The cost of each algorithm can be broken down into two categories: the development and the execution. Starting from the latter, the target platforms set stringent runtime constraints, where the algorithm must...

To be successor, every larger software project needs to be tested to verify the correct functionality and to enable its functionality to be extended flawlessly. The type of tests can be very different and depends on the kind of software project. Software projects, that are divided into several sub-projects require integration tests to verify that the individual parts work together correctly....

The Julia programming language has evolved into a mature tool for scientific computing over the past decade, offering high-level capabilities with just-in-time (JIT) compilation and efficient garbage collection. Its performance, comparable to that of C/C++, makes Julia an attractive option for the high-energy physics community. However, Julia's use of precompiled files to achieve this...

Implicit generative models have the capability to learn arbitrary complex data distributions. On the downside, training requires telling apart real data from artificially-generated ones using adversarial discriminators, leading to unstable training and mode-dropping issues. As reported by Zahee et al. (2017), even in the one-dimensional (1D) case, training a generative adversarial network...

The calorimeter in Large Hadron Collider (LHC) experiments measures particle energy by tracking showers from collisions. Describing these processes requires precise simulation methods, such as the Geant4 toolkit. Recently, generative models have emerged as a faster alternative based on different Machine Learning (ML) architectures, such as Diffusion and Variational Autoencoders.

Calculating differential cross-sections of scattering processes is a crucial observable in high-energy physics, used to predict experimental outcomes and test theoretical models. For perturbative quantum field theories, this involves generating all possible Feynman diagrams for a given scattering process and translating them into computable functions. This becomes cumbersome very rapidly,...

While IceCube’s detection astrophysical neutrinos at energies up to a few PeV has opened a new window to our Universe, much remains to be discovered regarding these neutrinos’ origin and nature. In particular, the difficulty differentiating 𝜈𝑒 and 𝜈𝜏 charged-current (CC) events in the energy limits our ability to measure this flux's flavor ratio precisely.

High energetic quarks and gluons, produced in a scattering phenomena, undergoes fragmentation and hadronization, leading to a spray of collimated particles, which are collectively clustered to form jets. In the ultra-high momentum regime, it may often happen that multiple energetic partons are within a geometric vicinity, and the jet thus formed has multiple sub-jets within it. This led to the...

During Run 3 of the LHC, trigger level analysis (TLA) offers the possibility of targetting new signals which other analyses are less sensitive to. I will showcase how Julia has been used as a part of the analysis workflow for a TLA search of a new heavy vector boson, Z', decaying to two bottom quarks. I will discuss the advantages and experience of using Julia in this analysis.

Though first intended as an interactive, productivity language, Julia has seen a surprising amount of interest as an alternative to C and C++. In this talk I will discuss why that is, and what we are doing to encourage and enable those use cases. Providing more compile-time safety and making it easier to deploy Julia programs are major areas of focus for the project and JuliaHub currently.
