A direct search for Dirac magnetic monopoles
… monopoles are highly ionizing and curve in the direction of the magnetic field. A new dedicated magnetic monopole trigger at CDF, which requires large light pulses in the scintillators of the time-of-flight system, remains highly efficient to monopoles while consuming a tiny fraction of the …

The Higgs boson in the Standard Model : theoretical constraints and a direct search in the WH channel at the Tevatron
Le mécanisme de Higgs du Modèle Standard (SM) peut expliquer l'origine de la masse. Il prédit également l'existence d'une particule non encore observée, le boson de Higgs, dont la masse n'est pas prédite par la théorie. Le boson de Higgs est fortement lié à la validité du SM à hautes énergies. On …

Direct search for exotic spin zero particles in the di-lepton final state of Higgs-Z associated production in sqrt(s) = 13 TeV pp collisions
This thesis presents a search for a new exotic spin-0 particle a in 36.47 fb^(-1) of sqrt(s) = 13 TeV pp collisions recorded by the ATLAS detector at the LHC. This analysis is part of a broader search for a H ==> aa ==> bbbb, which uses a Higgs produced in association with a weak vector boson to …

Deterministic Parallel Global Parameter Estimation for a Model of the Budding Yeast Cell Cycle
Two parallel deterministic direct search algorithms are combined to find improved parameters for a system of differential equations designed to simulate the cell cycle of budding yeast. Comparing the model simulation results to experimental data is difficult because most of the experimental data is …
