Direct top-quark decay width measurement in the tt¯lepton+jets channel at √s=8 TeV with the ATLAS experiment
(Peer reviewed; Journal article, 2018-02-15)This paper presents a direct measurement of the decay width of the top quark using tt¯ events in the lepton+jets final state. The data sample was collected by the ATLAS detector at the LHC in proton–proton collisions at a ... -
Direct two-photon double ionization of H2
(Peer reviewed; Journal article, 2012-06-05)We have studied the process of direct (nonsequential) two-photon double ionization of molecular hydrogen (H2). Solving the time-dependent Schr¨odinger equation by an ab initio method, total (generalized) and singledifferential ... -
Direct Visualization of CH4/CO2 Hydrate Phase Transitions in Sandstone Pores
(Journal article; Peer reviewed, 2021)This paper reports the formation and dissociation pattern of hydrate crystals with varying compositions of CH4 and CO2 in porous media. Direct visualization was carried out using a high-pressure, water-wet, silicon wafer-based ... -
Directed flow of charged particles at mid-rapidity relative to the spectator plane in Pb-Pb collisions at \(\sqrt{s_{NN}}\)=2.76 TeV
(Peer reviewed; Journal article, 2013-12)The directed flow of charged particles at midrapidity is measured in Pb-Pb collisions at \(\sqrt{s_{NN}}\).2.76 TeV relative to the collision plane defined by the spectator nucleons. Both, the rapidity odd \(v_1^{odd}\) ... -
Directed Network of Substorms Using SuperMAG Ground‐Based Magnetometer Data
(Peer reviewed; Journal article, 2019)We quantify the spatiotemporal evolution of the substorm ionospheric current system utilizing the SuperMAG 100+ magnetometers. We construct dynamical directed networks from this data for the first time. If the canonical ... -
Directional wave measurements from navigational buoys
(Journal article; Peer reviewed, 2022)In-situ wave measurements are often required by marine industry standards and for verification of coastal wave forecasts. Obtaining wave measurements is costly and it would be advantageous to utilize existing platforms ... -
Disentangling electron-boson interactions on the surface of a familiar ferromagnet
(Journal article; Peer reviewed, 2024)We report energy renormalizations from electron-phonon and electron-magnon interactions in spin minority surface resonances on Ni(111). The different interactions are identified, disentangled, and quantified from the ... -
Dispersion and two-phase flow in material from different carbonate pore classes
(Master thesis, 2008-06-02)Carbonate reservoirs are currently estimated to contain more than 50 % of the world's oil reserves. The economical value of improving knowledge on fluid flow in these reservoirs is therefore vast. Carbonate reservoirs are ... -
Distribution and Occurrence Frequency of dB/dt Spikes During Magnetic Storms 1980–2020
(Journal article; Peer reviewed, 2022)The physical magnetospheric cause for geomagnetically induced currents (GICs) are rapid time-varying magnetic fields (dB/dt), which occur mainly during magnetic substorms and storms. When, where and why exactly such rapid ... -
Distribution of energetic oxygen and hydrogen in the near-Earth plasma sheet
(Peer reviewed; Journal article, 2015-05)The spatial distributions of different ion species are useful indicators for plasma sheet dynamics. In this statistical study based on 7 years of Cluster observations, we establish the spatial distributions of oxygen ions ... -
Do the Throat Auroras Create Polar Cap Patches?
(Journal article; Peer reviewed, 2023)Throat auroras and polar cap patches are common phenomena in the polar ionosphere resulting from magnetosphere-ionosphere coupling. A campaign was organized, with all-sky imagers at Yellow River Station, the European ... -
Dos and Don’ts When Developing a System to Investigate Spontaneous Imbibition in Unconsolicdated Porous Media
(Peer reviewed; Journal article, 2019)This paper describes the development of a consistent model system to measure spontaneous imbibition and determine saturation functions in unconsolidated porous media. Sand grains or glass beads were packed in up to 0.5 m ... -
