A measurement of the forward-backward asymmetry (A [FB]) of Drell-Yan lepton pairs in pp
collisions at sqrt (s)= 7 TeV is presented. The data sample, collected with the CMS detector …

The CMS muon system has been aligned using cosmic-ray muons collected in 2008 and
beam-halo muons from the 2008 LHC circulating beam tests. After alignment, the resolution …

We present a measurement of the ratio of positive to negative muon fluxes from cosmic ray
interactions in the atmosphere, using data collected by the CMS detector both at ground …

A measurement of the underlying activity in scattering processes with p T scale in the GeV
region is performed in proton–proton collisions at s=0.9 TeV, using data collected by the …

The hadroproduction of quarkonia is not understood. None of the existing theories
successfully reproduces both the differential cross section and the polarization …

The paper presents a digest of the research results in the domain of accelerator science and
technology in Europe, shown during the annual meeting of the EuCARD–European …

Accelerator science and technology is one of a key enablers of the developments in the
