Study of the rare decays of B s0 and B 0 mesons into muon pairs using data collected during 2015 and 2016 with the ATLAS detector
(Springer Verlag, 2019)
A study of the decays B s 0 → μ + μ − and B 0 → μ + μ − has been performed using 26.3 fb −1 of 13 TeV LHC proton-proton collision data collected with the ATLAS detector in 2015 and 2016. Since the detector resolution in ...
Search for heavy Majorana or Dirac neutrinos and right-handed W gauge bosons in final states with two charged leptons and two jets at √s=13 TeV with the ATLAS detector
(Springer Verlag, 2019)
A search for heavy right-handed Majorana or Dirac neutrinos NR and heavy right-handed gauge bosons WR is performed in events with a pair of energetic electrons or muons, with the same or opposite electric charge, and two ...
Search for heavy neutral leptons in decays of W bosons produced in 13 TeV pp collisions using prompt and displaced signatures with the ATLAS detector
(Springer, 2019-10)
The problems of neutrino masses, matter-antimatter asymmetry, and dark matter could be successfully addressed by postulating right-handed neutrinos with Majorana masses below the electroweak scale. In this work, leptonic ...
Cross-section measurements of the Higgs boson decaying into a pair of τ -leptons in proton-proton collisions at s =13 TeV with the ATLAS detector
(American Physical Society, 2019)
A measurement of production cross sections of the Higgs boson in proton-proton collisions is presented in the H→ττ decay channel. The analysis is performed using 36.1 fb-1 of data recorded by the ATLAS experiment at the ...
Search for vector-boson resonances decaying to a top quark and bottom quark in the lepton plus jets final state in pp collisions at √s=13TeV with the ATLAS detector
(Elsevier B.V., 2019)
A search for new charged massive gauge bosons, W′, is performed with the ATLAS detector at the LHC. Data were collected in proton–proton collisions at a center-of-mass energy of s=13 TeV and correspond to an integrated ...
Measurements of W and Z boson production in pp collisions at √s=5.02 TeV with the ATLAS detector
(Springer New York LLC, 2019)
Measurements of fiducial integrated and differential cross sections for inclusive W+, W- and Z boson production are reported. They are based on 25.0±0.5pb-1 of pp collision data at s=5.02 TeV collected with the ATLAS ...
Search for heavy charged long-lived particles in proton–proton collisions at √s=13TeV using an ionisation measurement with the ATLAS detector
(Elsevier B.V., 2019)
This Letter presents a search for heavy charged long-lived particles produced in proton–proton collisions at s=13TeV at the LHC using a data sample corresponding to an integrated luminosity of 36.1fb−1 collected by the ...
Measurement of fiducial and differential W+W- production cross-sections at √s=13 TeV with the ATLAS detector
(Springer New York LLC, 2019-10)
A measurement of fiducial and differential cross-sections for W+W- production in proton–proton collisions at s=13 TeV with the ATLAS experiment at the Large Hadron Collider using data corresponding to an integrated luminosity ...
Measurement of W± -boson and Z-boson production cross-sections in pp collisions at √s=2.76 TeV with the ATLAS detector
(Springer, 2019-11)
The production cross-sections for W± and Z bosons are measured using ATLAS data corresponding to an integrated luminosity of 4.0 pb- 1 collected at a centre-of-mass energy s=2.76 TeV. The decay channels W→ ℓν and Z→ ℓℓ are ...
Resolution of the ATLAS muon spectrometer monitored drift tubes in LHC Run 2
(Institute of Physics Publishing, 2019-09)
The momentum measurement capability of the ATLAS muon spectrometer relies fundamentally on the intrinsic single-hit spatial resolution of the monitored drift tube precision tracking chambers. Optimal resolution is achieved ...
