... ducting magnet has been built, covering the full angular acceptance around the beam axis to increase the statis- tics and remove possible azimuthal asymmetry (see fig- ure 9). The target was 20 cm long and was filled ... See full document

... The LHCb subcomponents can be split into the follow- ing two categories: tracking detectors, which are used to reconstruct the trajectories and momenta of charged par- ticles, and particle identification detectors, which ... See full document

... neutron capture on hydrogen (nH) by Daya Bay experiment. The background of nH analysis is higher, the neutron capture time (200ms) is longer, and the energy neutron captured on hydrogen is lower (2.2MeV). To meet ... See full document

... ATLAS has also studied production of prompt photons produced in Pb+Pb collisions [17]. Prompt photons have two primary sources: direct emission via quark-gluon Compton scattering or quark- antiquark annihilation, or in ... See full document

... The DP γ +jet + dijet event sample is selected from DØ data with a single p p ¯ collision vertex [3]. The collected statistics of the sample corresponds to the integrated luminosity of 8.7 fb − 1 . Each event must ... See full document

... Instead of detailing this method, let me here just highlight some of its beautiful applica- tions and results. The azimuthally uniform distribution of the scattering angle θ ∗ demonstrates the azimuthal symmetry ... See full document
