Properties of g → bb̅ at Small Opening Angles in pp Collisions with the ATLAS Detector at √s =13 TeV
The fragmentation of high-energy gluons at small opening angles is largely unconstrained by present measurements. Gluon splitting to b-quark pairs is a unique probe into the properties of gluon fragmentation because ...
Search for the Standard Model Higgs Boson Decay to μ⁺μ⁻ with the ATLAS Detector
(Elsevier Science B. V., 2014-11-10)
A search is reported for Higgs boson decay to μ⁺μ⁻ using data with an integrated luminosity of 24.8 fb⁻¹ collected with the ATLAS detector in pp collisions at √s̅ = 7 and 8 TeV at the CERN Large Hadron Collider. The observed ...
Search for Heavy Resonances Decaying to a W or Z Boson and a Higgs Boson in the qq̅(′)bb̅ Final State in pp Collisions at √s =13 TeV with the ATLAS Detector
(Elsevier Science Bv, 2018-09-27)
A search for heavy resonances decaying to a W or Z boson and a Higgs boson in the qq̅(′)bb̅ final state is described. The search uses 36.1 fb⁻¹ of proton-proton collision data at √s = 13 TeV collected by the ATLAS detector ...
Constraints on New Phenomena via Higgs Boson Couplings and Invisible Decays with the ATLAS Detector
(Springer, 2015-11-30)
The ATLAS experiment at the LHC has measured the Higgs boson couplings and mass, and searched for invisible Higgs boson decays, using multiple production and decay channels with up to 4.7 fb⁻¹ of pp collision data at √s̅ ...
Search for a Light Higgs Boson Decaying to Two Gluons or ss̅ in the Radiative Decays of ϒ(1s)
(American Physical Society, 2013-08-06)
We search for the decay ϒ(1s) → γA⁰, A⁰ → gg or ss̅, where A⁰ is the pseudoscalar light Higgs boson predicted by the next-to-minimal supersymmetric Standard Model. We use a sample of (17.6 ± 0.3) x10⁶ ϒ(1s) mesons produced ...
Search for Lepton-Flavour-Violating H → μτ Decays of the Higgs Boson with the ATLAS Detector
(Springer, 2015-11-30)
A direct search for lepton-flavour-violating H -> mu tau decays of the recently discovered Higgs boson with the ATLAS detector at the LHC is presented. The analysis is performed in the H -> mu tau(had) channel, where ...
Search for Higgs Boson Pair Production in the bb̅bb̅ Final State from pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
(Springer, 2015-09-09)
A search for Higgs boson pair production pp → hh is performed with 19.5 fb⁻¹ of proton-proton collision data at √s̅ = 8 TeV, which were recorded by the ATLAS detector at the Large Hadron Collider in 2012. The decay products ...
Search for a Light Higgs Resonance in Radiative Decays of the ϒ(1S) with a Charm Tag
(American Physical Society, 2015-04-10)
A search is presented for the decay ϒ(1S)→γA⁰, A⁰→cc̅, where A⁰ is a candidate for the CP-odd Higgs boson of the next-to-minimal supersymmetric standard model. The search is based on data collected with the BABAR detector ...
Measurement of the Higgs Boson Mass from the H → γγ and H → ZZ* → 4ℓ Channels in pp Collisions at Center-Of-Mass Energies of 7 and 8 TeV with the ATLAS Detector
(American Physical Society, 2014-09-09)
An improved measurement of the mass of the Higgs boson is derived from a combined fit to the reconstructed invariant mass spectra of the decay channels H → γγ and H → ZZ∗ → 4ℓ. The analysis uses the pp collision data sample ...
Search for Invisible Higgs Boson Decays in Vector Boson Fusion at √s = 13 TeV with the ATLAS Detector
(Elsevier B.V., 2019-06-10)
We report a search for Higgs bosons that are produced via vector boson fusion and subsequently decay into invisible particles. The experimental signature is an energetic jet pair with invariant mass of O(1)TeV and O(100)GeV ...
