Charge Symmetry Violation Quark Distributions via Precise Measurement of π+/π− Ratios in Semi-inclusive Deep Inelastic Scattering
… are related to those in the neutron. Indirect experimental evidence constrains Charge Symmetry Violation (CSV) to be less than 9%. In Quantum Chromo-Dynamics (QCD), charge symmetry is broken by the mass difference between the up and down quarks. CSV in the valence region can be extracted from …

Seeing the Forest Through the Trees: Knowledge Retrieval for Streamlining Particle Physics Analysis
… long-running scientific collaborations. Within experimental particle physics, such structured knowledge bases could expedite methodological and editorial review. Complementarily, within the broader scientific community, generative LLM systems grounded in published work could make for reliable …

The ruins of science : whatever happened to the Tevatron?
The Tevatron was the world's highest energy particle accelerator for more than two decades. Built at Fermi National Accelerator Laboratory in Batavia, Illinois in the early 1980s, the machine accelerated protons and antiprotons through its 4.26-mile ring of magnets and smashed them together in one …

Machine Learning for Exotic Particle Detection in Ultraperipheral Relativistic Heavy-Ion Collisions
High energy particle physics is the study of our universe's most fundamental particles and forces. One area of research in the field of particle physics is ultraperipheral collisions. Ultraperipheral collisions are collisions of relativistic nuclei in which the impact parameter is greater than the …

Designing an event display for the Transition Radiation Detector in ALICE
… Research (CERN). Reviews of the fields of particle physics and visualisation are presented to motivate formally designing this display for two different audiences. We formulate a methodology, based on successful design studies in similar fields, that involves experimental physicists in the …

Particle Physics in the LHC Era
<p>During the past 100 years experimental particle physicists have collected an impressive amount of data. Theorists have also come to understand this data extremely well. It was in the first half of the 20th century the efforts of the early pioneers of quantum mechanics laid the ground work for …

Experimental Inference of Particle Transport in Tokamak Plasmas
… understanding of fuel, impurity, and neutral particle dynamics. In this work, radial profiles of experimental particle transport coefficients have been inferred following laser blow-off (LBO) impurity injections into both Alcator C-Mod and DIII-D plasmas. Development of the Aurora modeling …

Measurement Of Angular Coefficients Of Drell-Yan E(+) E(-) Pairs In Ppbar Collisions At Square Root Of Center Of Mass Energy Of 1.96 Tev.
In this paper we present the status of the measurement of angular distributions of final state electrons in ppbar → γ*/Z → e+ e− + X events produced in the Z boson mass region at square root of center of mass energy of 1.96 TeV at the Tevatron. For this analysis, we have used the Run IIb2 dataset …

First multi-year muography of Etna Volcano
… their results, they concluded that ``there exist particles of unit charge, but with a mass larger than that of a normal free electron and much smaller than that of a proton''. For this reason, Anderson initially gave it the name of mesotron. In 1937 J. C. Street and E.C. Stevenson, while working …

Searching for long-lived particles Beyond the Standard Model with displaced vertex signatures using the ATLAS detector: Not all hopes for new physics die immediately
… searches assume that Beyond the Standard Model particles decay immediately after they are produced. However, there is no a priori motivation for this assumption. This thesis details part of the growing effort to use new unorthodox signatures to search for models where these particles are …
