Zwei-Kaonen-Produktion nahe der Schwelle in der Reaktion p d -> 3He K+ K- mit dem Experiment MOMO an COSY
(2002)
Das Experiment MOMO am Cooler Synchrotron COSY im Forschungszentrum Jülich untersucht mittels einer exklusiven Messung die schwellennahe Produktion π von Mesonen anhand der Reaktionen p d -> 3He π+ ...
Measurement of e–p → e–X differential cross sections at high Q2 and of the structure function xF3 with ZEUS at HERA
(2002)
The 16 pb-1 of e–p data taken with the ZEUS detector during the 1998/99 running period of HERA have been used to measure neutral current single- and double-differential cross sections in deep inelastic ...
Sensitivity of the ATLAS experiment in pp-collisions at a centre of mass energy of 14TeV at the LHC to a Higgs boson with large decay-width to invisible final states
(2012-01-20)
So far experimentally not ruled out, the stealthy Higgs scenario proposes a hidden scalar sector, to which only the Higgs has non-vanishing and possibly large couplings. Due to decays into the scalars the Higgs acquires a ...
Supersymmetry Phenomenology in the Context of Neutrino Physics and the Large Hadron Collider LHC
(2012-09-17)
Experimentally, it is well established that the Standard Model of particle physics requires an extension to accommodate the neutrino oscillation data, which indicates that at least two neutrinos are massive and that two ...
Beauty Photoproduction using Decays into Muons at HERA
(2008)
Inclusive cross-sections for the production of open beauty in ep collisions at HERA are measured. The data were recorded with the ZEUS detector between 1996 and 2000. The measurements are restricted to photoproduction ...
Development of a Benchmark Parameter Scan for Higgs Bosons in the NMSSM Model and a Study of the Sensitivity for H->AA->4τ in Vector Boson Fusion with the ATLAS Detector
(2008)
An evaluation of the discovery potential for NMSSM Higgs bosons of the ATLAS experiment at the LHC is presented. For this purpose, seven two-dimensional benchmark planes in the six-dimensional parameter space of the ...
Measurement of high-Q2 charged current cross sections in e+p deep inelastic scattering at HERA
(2004)
Cross sections for charged current deep inelastic scattering have been measured in e+p collisions at a center-of-mass energy of 318 GeV. The data collected with the ZEUS detector at HERA in the ...
Measurement of the Weak Mixing Angle and the Spin of the Gluon from Angular Distributions in the Reaction pp → Z/γ* + X → μ+μ- + X with ATLAS
(2013-11-15)
The measurement of the effective weak mixing angle with the ATLAS experiment at the LHC is presented. It is extracted from the forward--backward asymmetry in the polar angle distribution of the muons originating from $Z$ ...
Multivariate methods and the search for single top-quark production in association with a W boson in ATLAS
(2013-05-28)
This thesis describes three machine learning algorithms that can be used for physics analyses. The first is a density estimator that was derived from the Green’s function identity of the Laplace operator and is capable of ......
Search for Supersymmetry with Tau Leptons, Muons, Missing Transverse Momentum and Jets with the ATLAS Experiment at the Large Hadron Collider
(2013-09-16)
Beyond the established Standard Model (SM), the search for new physics is among the most important ventures of modern physics. Supersymmetry (SUSY) is a natural candidate for an extension of the SM to account for unexplained ...
