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 ...
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 ...
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.
The W boson production cross section ...

Higgs Boson Production Cross-Section Measurements in the Di-Tau Final State at ATLAS
(2022-04-07)
The origin of masses for massive elementary particles in the Standard Model (SM) is explained by the Higgs mechanism. With the discovery of a SM-like Higgs boson resonance in 2012 a variety of measurements have been conducted ......
Towards a measurement of the tHq process in channels with hadronic tau lepton decays
(2023-10-05)
This thesis presents the first study to find events of the rare tHq process with ATLAS data in channels with hadronically decaying τ. A baseline framework is developed to select as many signal events as possible in ...
Search for Higgs Boson Pair Production in the bb̅τ+τ- Final State with the ATLAS Experiment at the LHC
(2023-12-18)
A search for Higgs boson pair (HH) production in final states with two b quarks and two τ leptons using 139 fb-1 of proton–proton collision data at a centre-of-mass energy of 13 TeV recorded ...
