Cosmic ray muons for spent nuclear fuel monitoring
… fuel stored within dry casks using cosmic ray muons is developed. The motivation stems from the need to investigate whether the stored content agrees with facility declarations to allow proliferation detection and international treaty verification. Cosmic ray muons are charged particles …

Identifying muons for neutrino oscillation and cross section experiments
Neutrinos (v) are interesting for many reasons; they are the only fundamental fermions which are electrically neutral; their mass is orders of magnitude smaller than the lightest charged lepton, the electron; and their solely weak interactions make them an excellent probe of the weak nuclear force. …

W mass measurement with muons at SQRT.S. = 1.8 TeV
The mass of the W vector boson has been measured from an analysis of $W \to\ \mu\ \nu$ decays in the CDF detector at the Fermilab Tevatron $\bar p p$ collider. The mass is 79.90 $\pm$ 0.53(stat.) $\pm$ 0.31(sys.) $\pm$ 0.16(scale) GeV/c$\sp2$. When this result is combined with previous CDF …

Zenith Angle Dependence of Prompt Muons in High Energy Cosmic Showers
The prompt component of cosmic showers received increasing interest in the last decade because of its potential to expose us to new physics and to help us explore the universe using neutrino telescopes. In this study we investigate the zenith angle dependence of the prompt component for energy …

Studies of rare B-meson decays to muons at the LHCb experiment
In this dissertation, very rare decays of B-mesons to purely muonic final states, both dimuon and four-muon, are studied at the LHCb experiment using data recorded during the first and second data-taking periods of the Large Hadron Collider, spanning the years 2011–2012 and 2015–2018, respectively. …

Study of muons associated with jets in proton-antiproton collisions at sqrt.s = 1.8 TeV
Production of heavy quark flavors in proton-antiproton collisions with a center-of-mass energy of 1.8 $\times$ 10$\sp{12}$ electron volts is studied for events containing hadronic jets with a nearby muon track, where both the jet and the muon are produced at large angles from the incident beams. …

Metrics, Muons, Moments, Models, Machine Learning, Measurements, and More: A Manifesto on Collider Physics
The interface between particle theory and particle experiments is essential to improving our understanding of the Standard Model and looking for new physics beyond it. At this interface lies a complicated web of complex and expensive simulations that cannot fully be trusted, experimental and …

Mise au point d'une méthode de tomographie utilisant les muons d'origine cosmique : Applications au laboratoire souterrain du Mont Terri et au volcan de la Soufrière de Guadeloupe
Les muons sont produits suite aux interactions de particules cosmiques avec l'atmosphère. La faible probabilité d'interaction des muons avec la matière leur permet d'atteindre la croûte terrestre et d'en traverser les premiers kilomètres. L'étude de l'atténuation du flux de muons permet alors …

Particle Identification with the ND280 Fine Grained Detectors for the T2K Experiment
… identification of particles (protons, electrons, muons and pions) with trajectories contained within the Fine Grained Detectors of the T2K (Tokai-to-Kamioka) experiment. This is achieved by constructing a distribution that compares the distance and the energy deposited by a particle travelling in …
