Spin alignment measurements of the K*0(892) and phi (1020) vector mesons in heavy ion collisions at s(NN)**(1/2) = 200 GeV.

The first spin alignment measurements for the K 0 (892) and ?(1020) vector mesons produced at mid-rapidity with transverse momenta up to 5 GeV/c at root s = 200 GeV at RHIC are presented....

Nuclear-modification factor for open-heavy-flavor production at forward rapidity in Cu+Cu collisions at sNN=200 GeV

The charm-production cross section in p + p collisions at root s = 200 GeV, integrated over p(T) and in the rapidity range 1.4 < y < 1.9, is found to be d(sigma e (e) over bar)/dy = 0.139 +/- 0.029 (stat)(-0.058)(+0.051) (syst) mb....

Energy Loss in Heavy Ion Collisions

Results of analysis of energy scanned spectra of charged hadronsproduced in AuAucollisions at s1/2= 200, 130, 62.4, 9.2GeV in the z-scaling approach were presented. We argue that z-scaling s the self-similarity, locality, and fractality of hadron int...

Search for strong gravity signatures in same-sign dimuon final states using the ATLAS detector at the LHC

A search for microscopic black holes has been performed in a same-sign dimuon final state using 1.3 fb^-1 of proton-proton collision data collected with the ATLAS detector at a centre of mass energy of 7 TeV at the CERN Large Hadron Collider. The dat...

Determination of the strange-quark density of the proton from ATLAS measurements of the W -> lv and Z -> ll cross sections

A QCD analysis is reported of ATLAS data on inclusive W and Z boson production in pp collisions at the LHC, jointly with ep deep inelastic scattering data from HERA. The ATLAS data exhibit sensitivity to the light quark sea composition and magnitude ...

Search for a light Higgs boson decaying to long-lived weakly-interacting particles in proton-proton collisions at sqrt{s} = 7 TeV with the ATLAS detector

A search for the decay of a light Higgs (120 - 140 GeV) to a pair of weakly-interacting, long-lived particles in 1.94 fb^-1 of proton-proton collisions at sqrt{s} = 7 TeV recorded in 2011 by the ATLAS detector is presented. The search strategy requir...

Measurement of the W ??? cross section in pp collisions at s = 7 TeV with the ATLAS experiment

The cross section for the production of W bosons with subsequent decay W to tau nu is measured with the ATLAS detector at the LHC. The analysis is based on a data sample that was recorded in 2010 at a proton-proton center-of-mass energy of sqrt(s) = ...

Measurement of W gamma and Z gamma production cross sections in pp collisions at sqrt(s) = 7 TeV and limits on anomalous triple gauge couplings with the ATLAS detector

This Letter presents measurements of l nu gamma and l^+ l^- gamma (l=e, mu) production in 1.02 fb^-1 of pp collision data recorded at sqrt(s) = 7 TeV with the ATLAS detector at the LHC during 2011. Events dominated by W gamma and Z gamma production w...
