Abstract
Geant4 is a software toolkit for the simulation of the passage of particles through matter. It is used by a large number of experiments and projects in a variety of application domains, including high energy physics, astrophysics and space science, medical physics and radiation protection. Over the past several years, major changes have been made to the toolkit in order to accommodate the needs of these user communities, and to efficiently exploit the growth of computing power made available by advances in technology. The adaptation of Geant4 to multithreading, advances in physics, detector modeling and visualization, extensions to the toolkit, including biasing and reverse Monte Carlo, and tools for physics and release validation are discussed here.

0.1–10 MeV Neutron Soft Error Rate in Accelerator and Atmospheric Environments

TL;DR: In this article, the authors evaluated neutrons with energies between 0.1 and 10 MeV with respect to the soft error rate (SER) in SRAMs manufactured in scaled technologies.
Journal ArticleDOI

Cornucopia of Antineutrons and Hyperons from a Super J/ψ Factory for Next-Generation Nuclear and Particle Physics High-Precision Experiments.

TL;DR: In this article, the authors point out and investigate a new high-quality source of baryons and antibaryons with precisely known kinematics, which open fresh opportunities for applications in particle and nuclear physics, including antinucleon-nucleon interaction, non-valence $s\bar{s}$ component of the nucleon, (anti)hyperon nucleon interactions, OZI violation, (multi-strange) hypernuclei, exotic light hadron spectroscopy and many others, as well as calibration of Monte Carlo

Influences of 3D PET scanner components on increased scatter evaluated by a Monte Carlo simulation.

TL;DR: It is concluded that the precise construction was not needed; the shields, the tunnel, the bed and the object were sufficient for accurate scatter simulations and were confirmed by visualization of photon trajectories.

Search for lepton number and flavour violation in $K^+ $ and $\pi^0$ decays

R. Aliberti, +201 more
TL;DR: In this article, the lepton number and lepton flavour decay was investigated using data collected by the NA62 experiment at CERN in $2017$-$2018 and no evidence for these decays was found and upper limits of the branching ratios were obtained at 90% confidence level.
