Two- and three-pion quantum statistics correlations in Pb-Pb collisions at √sNN = 2.76 TeV at the CERN Large Hadron Collider
(American Physical Society, 2014-02-26)
Correlations induced by quantum statistics are sensitive to the spatiotemporal extent as well as dynamics of particle-emitting sources in heavy-ion collisions. In addition, such correlations can be used to search for the ...
Measurement of the electroweak production of dijets in association with a Z-boson and distributions sensitive to vector boson fusion in proton-proton collisions at √s= 8 TeV using the ATLAS detector
Measurements of fiducial cross sections for the electroweak production of two jets in association with a Z-boson are presented. The measurements are performed using 20.3 fb−1 of proton-proton collision data collected at a ...
Measurement of negatively charged pion spectra in inelastic p+p interactions at plab= 20, 31, 40, 80 and 158 GeV/c
We present experimental results on inclusive spectra and mean multiplicities of negatively charged pions produced in inelastic p+p interactions at incident projectile momenta of 20, 31, 40, 80 and 158 GeV/c ( √s= 6.3, 7.7, ...
Acoustic Methods for Obtaining the Pressure Reflection Coefficient from a Buffer Rod Based Measurement Cell
The known acoustic methods for obtaining the pressure reflection coefficient from a buffer rod based measurement cell are presented, along with 2 new generic approaches for measuring the pressure reflection coefficient ...

Study of heavy-flavor quarks produced in association with top-quark pairs at √s =7 TeV using the ATLAS detector
(American Physical Society, 2014-04-21)
Using a sample of dilepton top-quark pair (tt¯) candidate events, a study is performed of the production of top-quark pairs together with heavy-flavor (HF) quarks, the sum of tt¯+b+X and tt¯+c+X, collectively referred to ...
Measurement of the production cross-section of ψ(2S) → J/ψ(→μ+μ−)π+π− in pp collisions at √s = 7 TeV at ATLAS
The prompt and non-prompt production cross-sections for ψ(2S) mesons are measured using 2.1 fb−1 of pp collision data at a centre-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. The measurement exploits ...
Search for contact interactions and large extra dimensions in the dilepton channel using proton–proton collisions at √s=8 TeV with the ATLAS detector
(Springer Berlin Heidelberg, 2014-12-11)
A search is conducted for non-resonant new phenomena in dielectron and dimuon final states, originating from either contact interactions or large extra spatial dimensions. The LHC 2012 proton–proton collision dataset ...
Evidence for electroweak production of W±W±jj in pp collisions at √s =8 TeV with the ATLAS detector
(American Physical Society, 2014-10-03)
This Letter presents the first study of W±W±jj, same-electric-charge diboson production in association with two jets, using 20.3 fb−1 of proton-proton collision data at s√=8 TeV recorded by the ATLAS detector at the Large ...
Search for pair and single production of new heavy quarks that decay to a Z boson and a third-generation quark in pp collisions at √s=8 TeV with the ATLAS detector
A search is presented for the production of new heavy quarks that decay to a Z boson and a third-generation Standard Model quark. In the case of a new charge +2/3 quark (T ), the decay targeted is T → Zt, while the decay ...
