Muon reconstruction efficiency and momentum resolution of the ATLAS experiment in proton–proton collisions at √s=7 TeV in 2010
This paper presents a study of the performance of the muon reconstruction in the analysis of proton–proton collisions at √s = 7TeV at the LHC, recorded by the ATLAS detector in 2010. This performance is described in ...
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 inclusive isolated prompt photons cross section in pp collisions at √s =7TeV with the ATLAS detector using 4.6fb-1
(American Physical Society, 2014-03)
A measurement of the cross section for the production of isolated prompt photons in pp collisions at a center-of-mass energy √s=7 TeV is presented. The results are based on an integrated luminosity of 4.6 fb−1 collected ...
Measurement of the production cross section of prompt J/ψ mesons in association with a W± boson in pp collisions at √s = 7 TeV with the ATLAS detector
The process pp → W ± J/ψ provides a powerful probe of the production mechanism of charmonium in hadronic collisions, and is also sensitive to multiple parton interactions in the colliding protons. Using the 2011 ATLAS ...
