Search for higgs and z boson decays to phi gamma with the atlas detector
A search for the decays of the Higgs and Z bosons to a phi meson and a photon is performed with a pp collision data sample corresponding to an integrated luminosity of 2.7 fb(-1) collected at root s = 13 TeV with the ATLAS ...
Measurement of the W boson polarisation in t(t)over-bar events from pp collisions at root s = 8 TeV in the lepton + jets channel with ATLAS (vol 77, pg 264, 2018)
This change does not have any impact on the measured helicity fractions, but it changes the obtained limits on the anomalous couplings.
Search for lepton-flavour-violating decays of the Higgs and Z bosons with the ATLAS detector
Direct searches for lepton flavour violation in decays of the Higgs and Z bosons with the ATLAS detector at the LHC are presented. The following three decays are considered: H -> e tau, H -> mu tau, and Z -> mu tau. The ...
Combined measurement of the higgs boson mass in pp collisions at root s=7 and 8 tev with the atlas and cms experiments
A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H -> gamma gamma and H -> ZZ -> 4l decay channels. The results are obtained from ...
Luminosity determination in pp collisions at root s=8 TeV using the ATLAS detector at the LHC
The luminosity determination for the ATLAS detector at the LHC during pp collisions at root s = 8 TeV in 2012 is presented. The evaluation of the luminosity scale is performed using several luminometers, and comparisons ...
Performance of the ATLAS trigger system in 2015
During 2015 the ATLAS experiment recorded 3.8 fb(-1) of proton-proton collision data at a centre-of-mass energy of 13 TeV. The ATLAS trigger system is a crucial component of the experiment, responsible for selecting events ...
Observation of an excited b-c(+/-) meson state with the atlas detector
A search for excited states of the B-c(+/-) meson is performed using 4.9 fb(-1) of 7 TeV and 19.2 fb(-1) of 8 TeV pp collision data collected by the ATLAS experiment at the LHC. A new state is observed through its hadronic ...
Search for the dimuon decay of the higgs boson in pp collisions at root s=13 tev with the atlas detector
A search for the dimuon decay of the Higgs boson was performed using data corresponding to an integrated luminosity of 36.1 fb(-1) collected with the ATLAS detector in pp collisions at root s = 13 TeV at the Large Hadron ...
