Reconstruction of hadronic decay products of tau leptons with the ATLAS experiment
(2016)
This paper presents a new method of reconstructing the individual charged and neutral hadrons in tau decays with the ATLAS detector. The reconstructed hadrons are used to classify the decay mode and to calculate the visible ...
Observation of z(c)(3900)(0) in e(+)e(-) -> pi(0)pi(0) j/psi
(2015)
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, we observe a new neutral state Z(c)(3900)(0) with a significance of 10.4 sigma. The mass and width are measured to be 3894.8 +/- ...
Precision measurement of the e(+)e(-) -> lambda(+)(c)(lambda)over-bar(c)(-) cross section near threshold
(2018)
The cross section of the e(+)e(-) -> Lambda(+)(c)(Lambda) over bar (-)(c) process is measured with unprecedented precision using data collected with the BESIII detector at root s = 4574.5, 4580.0, 4590.0 and 4599.5 MeV. ...
Determination of the spin and parity of the z(c)(3900)
(2017)
The spin and parity of the Z(c)(3900)(+/-) state are determined to be J(P) = 1(+) with a statistical significance larger than 7 sigma over other quantum numbers in a partial wave analysis of the process e(+)e(-) -> pi(+)pi(-) ...
Topological cell clustering in the ATLAS calorimeters and its performance in LHC Run 1
(2017)
The reconstruction of the signal from hadrons and jets emerging from the proton-proton collisions at the Large Hadron Collider (LHC) and entering the ATLAS calorimeters is based on a three-dimensional topological clustering ...
Search for the decay of the higgs boson to charm quarks with the atlas experiment
(2018)
A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZH -> l(+)l(-) cc is studied. A data set with an ...
Jet reconstruction and performance using particle flow with the ATLAS Detector
(2017)
This paper describes the implementation and performance of a particle flow algorithm applied to 20.2 fb(-1) of ATLAS data from 8 TeV proton-proton collisions in Run 1 of the LHC. The algorithm removes calorimeter energy ...
Measurements of electroweak W j j production and constraints on anomalous gauge couplings with the ATLAS detector
(2017)
Measurements of the electroweak production of a W boson in association with two jets at high dijet invariant mass are performed using root s = 7 and 8 TeV proton-proton collision data produced by the Large Hadron Collider, ...
Measurements of top-quark pair differential cross-sections in the e mu channel in pp collisions at root s=13 TeV using the ATLAS detector
(2017)
This article presents measurements of t (t) over bar differential cross-sections in a fiducial phase-space region, using an integrated luminosity of 3.2 fb(-1) of proton-proton data at a centre-of-mass energy of root s = ...
Measurement of differential cross-sections of a single top quark produced in association with a W boson at root s=13TeV with ATLAS
(2018)
The differential cross-section for the production of a W boson in association with a top quark is measured for several particle-level observables. The measurements are performed using 36.1 fb(-1) of pp collision data ...
