Pseudo-top-antitop cross sections (ATLAS_2015_I1345452)

Inspire | HepData | arXiv:1502.05923 [hep-ex]

Various differential cross-sections are measured in top-quark pair ($t\bar{t}$) events produced in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=7$ TeV at the LHC with the ATLAS detector. These differential cross-sections are presented in a data set corresponding to an integrated luminosity of 4.6 fb$^{-1}$. The differential cross-sections are presented in terms of kinematic variables of a top-quark proxy referred to as the pseudo-top-quark whose dependence on theoretical models is minimal. The pseudo-top-quark can be defined in terms of either reconstructed detector objects or stable particles in an analogous way. The measurements are performed on $t\bar{t}$ events in the lepton+jets channel, requiring exactly one charged lepton and at least four jets with at least two of them tagged as originating from a $b$-quark. The hadronic and leptonic pseudo-top-quarks are defined via the leptonic or hadronic decay mode of the W boson produced by the top-quark decay in events with a single charged lepton. The cross-section is measured as a function of the transverse momentum and rapidity of both the hadronic and leptonic pseudo-top-quark as well as the transverse momentum, rapidity and invariant mass of the pseudo-top-quark pair system. The measurements are corrected for detector effects and are presented within a kinematic range that closely matches the detector acceptance.

Measurements of cross sections for the production of a $W$ boson in association with jets in proton–proton collisions at $\sqrt{s} = 7$ TeV with the ATLAS experiment at the Large Hadron Collider. With an integrated luminosity of 4.6 $\text{fb}^{−1}$, this data set allows for an exploration of a large kinematic range, including jet production up to a transverse momentum of 1 TeV and multiplicities up to seven associated jets. The production cross sections for W bosons are measured in both the electron and muon decay channels. Differential cross sections for many observables are also presented including measurements of the jet observables such as the rapidities and the transverse momenta as well as measurements of event observables such as the scalar sums of the transverse momenta of the jets. The default routine will pick up the electron decay channel of the $W$ boson and compare it to the combined (muon and electron channel) data. Individual channels (for data) are available as well, use ATLAS_2014_I1312627_EL and ATLAS_2014_I1312627_MU to specify the decay channel directly.

Measurement of Z boson in association with b-jets at 7 TeV in ATLAS (muon channel) (ATLAS_2014_I1306294_MU)

Inspire | HepData | arXiv:1407.3643 [hep-ex] | JHEP 1410 (2014) 141

Measurements of differential production cross-sections of a $Z$ boson in association with $b$-jets in $pp$ collisions at $\sqrt{s}=7$ TeV are reported. The data analysed correspond to an integrated luminosity of 4.6 fb$^{-1}$ recorded with the ATLAS detector at the Large Hadron Collider. Particle-level cross-sections are determined for events with a $Z$ boson decaying into an electron or muon pair, and containing $b$-jets. For events with at least one $b$-jet, the cross-section is presented as a function of the $Z$ boson transverse momentum and rapidity, together with the inclusive $b$-jet cross-section as a function of $b$-jet transverse momentum, rapidity and angular separations between the $b$-jet and the $Z$ boson. For events with at least two $b$-jets, the cross-section is determined as a function of the invariant mass and angular separation of the two highest transverse momentum $b$-jets, and as a function of the $Z$ boson transverse momentum and rapidity. Results are compared to leading-order and next-to-leading-order perturbative QCD calculations. This Rivet module implements the event selection for Z decaying into muons.

Measurements of the differential cross section for the process $Z/\gamma^\ast \rightarrow l$ $(l = e, \mu)$ as a function of dilepton invariant mass in pp collisions at $\sqrt{s} = 7$ TeV. The measurement is performed in the $e$ and $\mu$ channels for invariant masses between 26 GeV and 66 GeV in the fiducial region $p_\text{T}^\text{leading} > 15$ GeV, $p_\text{T}^\text{subleading} > 12$ GeV, $|\eta| < 2.4$ using an integrated luminosity of 1.6 $\text{fb}^{-1}$. The analysis is extended to invariant masses as low as 12 GeV in the muon channel within a fiducal region of $p_\text{T}^\text{leading} > 9$ GeV, $p_\text{T}^\text{subleading} > 6$ GeV, $|\eta| < 2.4$ with 35 $\text{pb}^{-1}$.

W + charm production at 7 TeV (ATLAS_2014_I1282447)

Inspire | HepData | JHEP 1405 (2014) 068 | doi:10.1007/JHEP05(2014)068 | arXiv:1402.6263 [hep-ex]

This routine implements the measurement of $W$ boson production in association with a single charm quark with $4.6 \text{fb}^{-1}$ of $pp$ collision data at $\sqrt{s} = 7$ TeV collected with the ATLAS detector at the Large Hadron Collider. Results are quoted for the $W$ boson production decaying into either an electron or muon and the charm quark being identified as any charmed hadron above 5 GeV inside $\Delta R = 0.4$ of a jet with more than 25 GeV. Alternatively the presence of the charm quark is indicated by the presence of a $D$ or a $D^*$ meson with a $p_\text{T}$ above 8 GeV. The cross sections are quoted for the number of opposite sign minus same sign events, where the signs under consideration are the charge of the $W$ boson and the charmed hadrons tagging the event. Given are the integrated and differential cross sections as a function of the pseudorapidity of the lepton from the $W$-boson decay are measured. Additionally, the cross-section ratios $\sigma(W^+ + bar{c}) / \sigma(W^- + c)$ as well as the $p_\text{T}$ dependent cross sections of the $D$/$D^*$ mesons normalized to the $W$ inclusive cross sections are published. The measured data is unfolded to the Born level. One should therefore take care to run on samples without QED radiation off of the electrons. IMPORTANT NOTICE --- For the MC predictions in the paper, the branching fractions to $D$ and $D^*$ mesons have been adapted to be 0.2256 ($D$) and 0.2287 ($D^*$) (LEP/HERA combination). Some suggestion on how to do post-processing -- in case separate samples for $W^+ + c$ and $W^- + c$ and inclusive $W$ are used -- are included in the cc-file. This post-processing is needed to properly display the histograms for the cross section ratio plots $\sigma(W^+ + bar{c}) / \sigma(W^- + c)$ as well as for the cross section ratios of $W + D^{(*)}$ production over inclusive $W$ production ($\sigma(W^{+/-} D^{(*)}) / \sigma(W^{+/-})$) as a function of the $D^{(*)}$ meson transverse momentum.

Inclusive isolated prompt photon analysis with 2011 LHC data (ATLAS_2013_I1263495)

Inspire | HepData | arXiv:1311.1440 [hep-ex] | Phys.Rev. D89 (2014) 052004

A measurement of the cross section for the production of isolated prompt photons in pp collisions at a center-of-mass energy $sqrt{s} = 7$ TeV is presented. The results are based on an integrated luminosity of 4.6 fb$^{-1}$ collected with the ATLAS detector at the LHC. The cross section is measured as a function of photon pseudorapidity $\eta^\gamma$ and transverse energy $E_T^\gamma$ in the kinematic range $100 < E_T^\gamma < 1000$ GeV and in the regions $|\eta^\gamma| < 1.37$ and $1.52 < |\eta^\gamma| < 2.37$. The results are compared to leading-order parton-shower Monte Carlo models and next-to-leading order perturbative QCD calculations. Next to-leading-order perturbative QCD calculations agree well with the measured cross sections as a function of $E_T^\gamma$ and $\eta^\gamma$.

Inclusive diphoton $+ X$ events at $\sqrt{s} = 7$ TeV (ATLAS_2012_I1199269)

Inspire | HepData | arXiv:1211.1913 [hep-ex] | JHEP 1301 (2013) 086

The ATLAS experiment at the LHC has measured the production cross section of events with two isolated photons in the final state, in proton-proton collisions at $\sqrt{s} = 7$ TeV. The full data set collected in 2011, corresponding to an integrated luminosity of 4.9 fb$^{-1}$, is used. The amount of background, from hadronic jets and isolated electrons, is estimated with data-driven techniques and subtracted. The total cross section, for two isolated photons with transverse energies above 25 GeV and 22 GeV respectively, in the acceptance of the electromagnetic calorimeter ($|\eta|<1.37$ and $1.52<|\eta|<2.37$) and with an angular separation $\Delta R>0.4$, is $44.0^{+3.2}_{-4.2}$ pb. The differential cross sections as a function of the di-photon invariant mass, transverse momentum, azimuthal separation, and cosine of the polar angle of the largest transverse energy photon in the Collins--Soper di-photon rest frame are also measured. The results are compared to the prediction of leading-order parton-shower and next-to-leading-order and next-to-next-to-leading-order parton-level generators.

Differential cross sections are presented as a function of the angular separation of the $b$-hadrons and the $Z$ boson. In addition, inclusive measurements are presented. For both the inclusive and differential studies,different ranges of $Z$ boson momentum are considered.
