Ion-motion simulations of a plasma-wakefield experiment at FLASHForward / Kalvik, D (U. Oslo (main)) ; Drobniak, P (U. Oslo (main)) ; Peña, F (U. Oslo (main) ; LMU Munich (main)) ; Lindstrøm, C A (U. Oslo (main)) ; Beinortaite, J (DESY) ; Boulton, L (DESY) ; Caminal, P (DESY) ; Garland, J (DESY) ; Loisch, G (DESY) ; Svensson, J Björklund (DESY) et al.
In plasma-based acceleration, an ultra-relativistic particle bunch$\unicode{x2014}$or an intense laser beam$\unicode{x2014}$is used to expel electrons from its propagation path, forming a wake that is devoid of electrons. The ions, being significantly more massive, are often assumed to be stationary. [...]

Searching for the constituents of the atom / Freeman, Sean J (U. Manchester (main) ; CERN)
This is a short account of the research that established the electron, proton and neutron as the basic constituents of atoms. It is written from the point of view of a physicist rather than a historian and tries to explain the scientific pathways to establishing these atomic constituents..

Migrating CUDA to SYCL: A HEP Case Study with ROOT RDataFrame / Chen, Jolly (CERN ; Amsterdam U.) ; Dessole, Monica (CERN) ; Varbanescu, Ana-Lucia (Twente U., Enschede)
The world’s largest particle accelerator, located at CERN, produces petabytes of data that need to be analysed efficiently, to study the fundamental structures of our universe. ROOT RDataFrame is an open-source C++ data analysis interface, developed for this purpose. [...]

Micromegas detector response test at the new EAR2 neutron beam of n_TOF facility in view of the 243Am(n,f) measurement / Kyritsis, Nikolaos (Natl. Tech. U., Athens) ; Diakaki, Maria (Natl. Tech. U., Athens) ; Michalopoulou, Veatriki (Natl. Tech. U., Athens) ; Eleme, Zinovia (Ioannina U.) ; Patronis, Nikolaos (Ioannina U.) ; Michael Kokkoris (Natl. Tech. U., Athens) ; Vlastou, Roza (Natl. Tech. U., Athens) /n_TOF Collaboration
A key ingredient of the design of advanced nuclear systems, such as Generation IV reactors and accelerator driven systems, is the study of neutron induced fission reactions. Accurate cross-section data on key actinides is needed both for their operation and the handling of the nuclear waste. [...]

Detection of ionization electrons with hybrid pixel detectors for non-destructive beam profile measurements / Fleisig, C (CERN ; U. Toronto (main)) ; Braach, J (CERN) ; Cabrera, G (CERN) ; Jensen, S (CERN) ; Joul, J (CERN) ; McLean, M (CERN) ; Storey, J W (CERN)
The Beam Gas Ionization (BGI) profile monitor is an Ionization Profile Monitor used for continuous, non-destructive transverse beam profile measurements in synchrotrons at CERN. Electrons are produced when residual gas in the beam pipe is ionized by the proton or ion beams orbiting the particle accelerator. [...]

Accelerating Machine Learning Inference on GPUs with SYCL / Panagou, Ioanna-Maria (Thessaly U.) ; Bellas, Nikolaos (Thessaly U.) ; Moneta, Lorenzo (CERN) ; Sengupta, Sanjiban (CERN)
Recently, machine learning has established itself as a valuable tool for researchers to analyze their data and draw conclusions in various scientific fields, such as High Energy Physics (HEP). Commonly used machine learning libraries, such as Keras and PyTorch, might provide functionality for inference, but they only support their own models and are constrained by heavy dependencies, which render their deployment on embedded or bare-metal environments infeasible. [...]

Improving Performance Portability of the Procedurally Generated High Energy Physics Event Generator MadGraph Using SYCL / Nichols, Nathan S (Argonne (main)) ; Childers, J Taylor (Argonne (main)) ; Burch, Tyler James (Argonne (main)) ; Field, Laurence (CERN)
Event Generators are essential tools for simulating Standard Model particle interactions, representing the initial step in modeling proton-proton collisions in the Large Hadron Collider (LHC) at CERN. Traditionally relying on a few algorithms like MadGraph5_aMC@NLO, there is a pressing need for enhanced portability across diverse computing platforms. [...]

Enhancement of the DUNE FD1 X-ARAPUCA Photon Detection Efficiency and upgrade of the FD2 Photon Collector / Cattadori, C M (INFN, Milan Bicocca ; Milan Bicocca U.) /DUNE Collaboration
The Photon Detection System (PDS) of the first two DUNE far detectors (FD1 and FD2) is composed of 6000 and 672 photon detection units respectively, named X-Arapuca, of different size and geometry. The PDS will complement and boost the DUNE LArTPC for the detection of non beam events: the prompt light detection will improve their tagging, and at low energies it will enable the trigger and the calorimetry of the supernova neutrinos.

Measurement of the impact-parameter dependent azimuthal anisotropy in coherent ρ0 photoproduction with ALICE / Riffero, Andrea G (INFN, Turin ; U. Turin (main)) /ALICE Collaboration
Coherent vector meson photoproduction in ultraperipheral heavy-ion collisions is a well established tool to probe the gluon structure of the colliding nuclei. We will focus on the observation of quantum interference effects in the ρ 0 meson photoproduction, in the form of angular anisotropy [...]
