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 ...
Search for the associated production of a W boson and a top quark with the ATLAS detector at 7 TeV
(2015-06-03)
An analysis searching for the associated production of a W boson and a top quark based on 4.7 fb-1 proton collision data recorded by the ATLAS detector at the LHC in 2011 at a centre-of-mass energy of √s ...
Study of top-quark pair cross-section measurement in the dilepton channel with the ATLAS detector at the LHC
(2011-09-16)
The top quark is the heaviest of the known fundamental particles in the Standard Model (SM) with a mass of 173.3±1.1GeV. It is the sixth quark in the SM and the weak isospin partner of the bottom quark. Properties such as ......
Measurement of the Associated Production of a Single Top Quark and a W Boson in Single-Lepton Events with the ATLAS Detector
(2016-06-10)
The production of a single top quark in association with a W boson (Wt) is measured with the ATLAS detector using proton-proton collision events with one lepton, three jets and missing transverse energy at √s = 8 TeV. ...
Measurement of the top quark decay branching fraction ratio Rb = B(t → Wb)/B(t → Wq) and of the inclusive production cross section pp → tt in the dilepton channel at ATLAS
(2022-01-13)
The top quark branching fraction ratio Rb and the inclusive production cross section σ tt̄ are measured in the dilepton channel using 4.6 fb-1 of proton-proton collisions at the centre-of-mass ...
Confronting the R-parity-violating MSSM with Flavor Observables and Displaced Vertices
(2019-06-06)
Supersymmetry (SUSY) was proposed as one of the solutions to the hierarchy problem. In addition, R-parity (Rp) is often imposed in such models in order to e.g. avoid proton decay. These Rp -conserving ......
Various Phenomenological Aspects of the R-parity Violating MSSM
(2024-02-05)
The Standard Model (SM) faces both theoretical and experimental challenges that indicate the existence of physics beyond its current framework. Among the proposed extensions, supersymmetry (SUSY) emerges as a promising ...
Measurements of the mass and width of the W-boson, and test of lepton universality in W-boson decays with the ATLAS detector
(2023-04-20)
The Standard Model of particle physics serves as the predominant theory of the microscopic world for many decades. Many discoveries have been predicted by this model and it still provides a good fit for a wide variety of ......
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 ...
Search for Supersymmetry and kinematic endpoint measurement in final states with two tau leptons with the ATLAS detector at the LHC
(2011-10-21)
Discovery prospects for Supersymmetry in final states with at least two tau leptons and large missing transverse energy are evaluated for LHC proton-proton collisions measured with the ATLAS detector. In a first study based ......
