Measurements of differential t-channel single top-quark production cross-sections in proton–proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS detector
Seema-Mergelmeyer, Pienpen (2018-03-28)Proton-proton collision data at a centre-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, corresponding to an integrated luminosity of 20.2 fb<sup>-1</sup>, are used to measure absolute and normalised ... -
Measurements of the mass and width of the W-boson, and test of lepton universality in W-boson decays with the ATLAS detector
König, Philipp Thomas (2023-04-20)The Standard Model of particle physics serves as the predominant theory of the microscopic world for many decades. Many discoveries have been predicted by this model and it still provides a good fit for a wide variety of ... -
Measurements of the Top Quark Pair Production Cross Section in Lepton+Jets Final States using a Topological Multivariate Technique as well as Lifetime b-Tagging in Proton-Antiproton Collisions at √s=1.96 TeV with the D0 Detector at the Tevatron
Golling, Tobias (2005)Two alternative measurements of the ttbar production cross section at √s = 1.96 TeV in proton-antiproton collisions in the lepton+jets channel are presented. The ttbar production cross section is extracted by combining the ... -
Measuring cosmological weak lensing using the Advanced Camera for Surveys on board the Hubble Space Telescope
Schrabback-Krahe, Tim Richard Walter (2008)Following from the theory of General Relativity, light-bundles are deflected and differentially distorted while passing through the gravitational potential of matter inhomogeneities. The gravitational lensing effect caused ... -
Measuring Excitations of a Strongly Interacting Superfluid Fermi Gas
Kell, Andreas (2022-11-24)This thesis investigates experimentally the superfluid phase of strongly interacting ultracold Fermi gases. The diluteness of the considered gases of neutral atoms ensures that their interaction can be described by a single ... -
Measuring Radio Emission from Cosmic Ray Air Showers with a Digital Radio Telescope
Horneffer, Andreas (2006)The earth is continously bombarded by highly energetic particles, the cosmic radiation. Even 90 years after their discovery the origin and acceleration of the highest energy particles is still unknown. Air showers from ... -
Measuring the Gap and Investigating Non-equilibrium in the BEC-BCS Crossover
Harrison, Timothy Joseph (2017-09-15)This thesis presents a new Bose-Fermi mixture quantum gas experiment that has been used to measure the gap over the BEC-BCS crossover and investigate the non-equilibrium dynamics of a superfluid in response to a quench of ... -
Mechanical strain influence on functional signaling of neurons in vitro
Tarazi, Samar M. B. (2023-02-22)Neuronal cells are embedded in the soft brain tissue and are protected by the thick meninges, as well as the rigid skull bones. Despite being highly sensitive and vastly protected, neurons are prone to internal and external ... -
