Search for Pair Production of a New b′ Quark that Decays into a Z Boson and a Bottom Quark with the ATLAS Detector

G. Aad, B. Abbott, J. Abdallah, S. Abdel Khalek et autres

A search is reported for the pair production of a new quark ${b}^{\ensuremath{'}}$ with at least one ${b}^{\ensuremath{'}}$ decaying to a $Z$ boson and a bottom quark. The data, corresponding to $2.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity, were collected from $pp$ collisions …

Measurement of inclusive jet and dijet production in p p collisions at s = 7 TeV using the ATLAS detector

G. Aad, B. Abbott, J. Abdallah, A. A. Abdelalim et autres

Inclusive jet and dijet cross sections have been measured in proton-proton collisions at a center-of-mass energy of 7 TeV using the ATLAS detector at the Large Hadron Collider. The cross sections were measured using jets clustered with the anti-${k}_{t}$ algorithm with parameters …

Measurement of the azimuthal anisotropy for charged particle production in s N N = 2.76 TeV lead-lead collisions with the ATLAS detector

G. Aad, B. Abbott, J. Abdallah, S. Abdel Khalek et autres

Differential measurements of charged particle azimuthal anisotropy are presented for lead-lead collisions at $\sqrt{{s}_{NN}}=2.76$ TeV with the ATLAS detector at the LHC, based on an integrated luminosity of approximately 8 $\ensuremath{\mu}{\mathrm{b}}^{\ensuremath{-}1}$. This anisotropy is characterized via a Fourier expansion of the distribution …
