Transport of muonic atoms
Transport of muonic hydrogen and deuterium atoms in gaseous hydrogen and deuterium is studied in the diffusion approximation and by means of the multiple collision expansion. The diffusion coefficient is derived. Scattering kernels are computed from the kinematics of an inelastic binary collision. …

A determination of the formation rate of muonic hydrogen molecules in the MuCap experiment
The MuCap experiment measures the mu^- disappearance rate, l_-, in a gaseous hydrogen time projection chamber (TPC) and compares it to the free mu^+ decay rate, l_+, to obtain the mu p singlet capture rate L_S. The motivation is a determination of the pseudoscalar form factor, g_P, of the proton, …

Studies of b-associated production and muonic decays of neutral Higgs bosons at the ATLAS experiment within the Minimal Supersymmetric Standard Model
… bosons of the MSSM can be discovered in the muonic decay mode using 30 inverse femtobarns of data for low masses of the pseudoscalar boson A, if the model parameter tan(beta) is at least 20. For higher masses of the A, tan(beta) would need to be significantly higher to ensure a discovery in …

Muon regeneration in muon catalyzed dt-fusion
… individual reaction rates. The essential muonic excitation rates have been recalculated taking into account finite nuclear mass effects. The stopping power for a charged projectile in liquid heavy hydrogen is modified to account for dynamic screening effects and a density dependent …

Nuclear charge distribution of ¹⁸¹Ta
<p>The energies of the x rays emitted by the muonic atom of <sup>181</sup>Ta were measured by a Ge(Li) solid state detector. From the clustering of these gamma rays it was possible to identify the transitions of the muonic atom which produced them. When a form is chosen for the nuclear charge …

A High Precision Measurement of the Proton Charge Radius at JLab
… ($r_{p}$). In 2010, a new method using the muonic hydrogen ($\mu$H)\footnote{A muonic hydrogen has its orbiting electron replaced by a muon.} spectroscopy reported a $r_{p}$ result that was nearly ten times more precise but significantly smaller than the values from the compilation of all …

INELASTIC ELECTRON SCATTERING FROM MOLYBDENUM-92
… data are analyzed along with existing data and muonic atom data to provide an improved description of the groundstate charge distribution. The inelastic scattering data for 23 excited states have been further analyzed to extract electromagnetic transition densities. These densities are discussed …

Charged Vector Boson (W ±) production in simulated proton-proton collisions at √s = 5.36 TeV.
… The W ± boson production is studied via the muonic decay channel as W ± → μ±+νμ (–). It is theoretically motivated in the work that this process can serve as a probe of the initial state of the collision, since the W ± boson is produced in the hardest partonic interaction and neither the W ± …

Studies of rare B-meson decays to muons at the LHCb experiment
… 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. LHCb is a …

Development of a high-level trigger for the dimuon spectrometer of the ALICE experiment at the large hadron collider
… swamped by a large background from several other muonic sources. Due to the large data rate expected for ALICE and the limited bandwidth, a highly efficient and selective trigger is required for the experiment - the dimuon high-level trigger (dHLT). This thesis concerns the context, development …
