Efimov Effect in Pionless Effective Field Theory and its Application to Hadronic Molecules
(2016-02-12)
In the past years various new hadronic states were discovered in the charm and bottom meson sector by experiments like Belle, BES and Babar. Many of these states fit into the conventional charmonium or bottomonium spectrum, ......
Particle Physics from Singular Geometries
(2016-02-16)
We study string compactifications on spaces that are either partial or fully singular and analyze the symmetries in the effective theories that they generically give rise to. In the heterotic case we consider orbifolds and ...
Studies into the mis-identification probability of tau leptons and a measurement of the cross section σ(pp → W) × BR(W → τντ) at a center-of-mass energy of √s = 7 TeV with the ATLAS detector
(2016-02-23)
Since the start of data taking in the year 2009 the Large Hadron Collider has been operated very successfully. Next to the ongoing efforts to fully determine the properties of the newly found Higgs-like boson, precision ......
Coherence effects and spectroscopy in laser driven dense atomic vapour
(2016-02-24)
In this work quantum coherence effects in dense rubidium atomic vapour are investigated. Prepared in a laser driven atomic system, coherent effects, like the well-known electromagnetically induced transparency, have a ...
Experimental and theoretical studies of mononuclear high-valent nitrido-iron and oxo-iron complexes
(2016-05-12)
Nitrido-iron and oxo-iron complexes are important species in manifold biological and industrial processes. While nitrido-iron complexes are intermediates in biological and industrial nitrogen fixation, oxo-iron complexes ...
The Pixel-TPC: A feasibility study
(2016-05-17)
The Time Projection Chamber (TPC) as a detector system in particle physics offers continuous tracking with low material budget and therefore is considered in the design of the International Large Detector (ILD) at the ...
Dynamik und Korrelationen eines Bose-Einstein-Kondensats aus Licht
(2016-02-02)
Einer der bemerkenswertesten Aspekte der Bose-Einstein-Kondensation ist die natürliche Ausprägung von Korrelationen und langreichweitiger Ordnung in einem System, welches sich im thermischen Gleichgewicht befindet. ...
