摘要:Abstract(#br)We present a new measurement of the spin-dependent structure function g 1 d of the deuteron from deep inelastic scattering of 190 GeV polarized muons on polarized deuterons. The results are combined with our previous measurements of g 1 d . A perturbative QCD ev...

摘要:Abstract(#br)We report a large enhancement of 1.7 in deuteron polarization up to values of 0.6 due to frequency modulation of the polarizing microwaves in a two liter polarized target using the method of dynamic nuclear polarization. This target was used during a deep inelastic p...

摘要:Abstract(#br)The polarized target of the Spin Muon Collaboration at CERN was used for deep inelastic muon scattering experiments during 1993–1996 with a polarized muon beam to investigate the spin structure of the nucleon. Most of the experiments were carried out with longit...

摘要:Abstract(#br)A muon beam polarimeter was built for the SMC experiment at the CERN SPS, for beam energies of 100 and 190 GeV. The beam polarisation is determined from the asymmetry in the elastic scattering off the polarised electrons of a ferromagnetic target whose magnetisa...

摘要:Abstract(#br)We present a new measurement of the spin-dependent structure function g 1 d of the deuteron in deep inelastic scattering of 190 GeV polarised muons on polarised deuterons, in the kinematic range 0.003 < x < 0.7 and 1 GeV 2 < Q 2 < 60 GeV 2 . This structure funct...

摘要:Abstract(#br)With its large acceptance and particle identification coverage the NA49 experiment (Fig. 1) can study hadron production in a wide range of high energy reactions [1]. Originally aimed at examining central Pb+Pb collisions for signatures of quark-gluon plasma formation...

摘要:Abstract(#br)Source imaging methodology is used to provide a three-dimensional two-pion source function for mid-rapidity pion pairs with p T < 70 MeV / c in central (0–7%) Pb + Pb collisions at s NN = 17.3 GeV . Prominent non-Gaussian tails are observed in the pion pair tran...
