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 ...
A Sensitivity Study for Higgs Boson Production in Vector Boson Fusion in the H → ττ →lh + 3ν Final State with ATLAS
(2012-02-17)
For a hypothetical Higgs boson mass between 114.4GeV and about 135GeV the production by Vector Boson Fusion and the decay H → ττ →lh + 3ν is one of the most promising discovery channels at the LHC. In this thesis, a study ......
W → τντ Cross Section Measurement and Search for the Standard Model Higgs Boson in the τlep τhad Final State with the ATLAS Detector
(2015-03-13)
Two measurements based on proton-proton collisions recorded with the ATLAS experiment at the LHC with τ leptons and missing transverse energy in the final state are presented.

Precision Calculations in Supersymmetric Models using Phenomenological Tools
(2016-12-21)
We present a Higgs mass calculation at two-loop level based on the effective potential approach, which has been made available in the public computer codes SARAH and SPheno. The approach is based on generic formulae for ...
Search for the Higgs Boson Decay into Bottom and Charm Quarks Using Proton-Proton Collisions at √s = 13 TeV
(2019-02-05)
A search for the Standard Model (SM) Higgs boson, produced in association with a Z boson, in decays to bottom or charm quarks is presented. The SM Higgs boson mass is assumed to be 125 GeV. These searches analyse a data ...
