Wie sind Kinder- und Jugendkliniken in Nordrhein-Westfalen auf die Überwindung von Sprachbarrieren vorbereitet? – Eine Pilotstudie zur Strukturqualit…

2016

Zusammenfassung Ziel der Studie Der Anteil von Kindern mit Migrationshintergrund unter 5 Jahren liegt bundesweit bei 35%, in Nordrhein-Westfalen (NRW) bei 43%. Häufig sind mit dem Migrationshintergrund unzureichende Deutschkenntnisse bei einem oder beiden Elternteilen verbunden. Kommunikationsbarrieren durch Sprachdifferenzen haben einen negativen Einfluss auf die Behandlungsqualität, Patientensicherheit und Behandlungskosten. Es wird untersucht, wie Kinder- und Jugendkliniken auf die Herausforderung durch Sprachbarrieren vorbereitet sind. Methodik Wir führten eine Querschnittsbefragung aller Kinderkliniken in NRW durch und luden dazu die Klinikdirektoren schriftlich und per email zur Teiln…

Spin asymmetry A1d and the spin-dependent structure function g1d of the deuteron at low values of x and Q2

2007

Abstract We present a precise measurement of the deuteron longitudinal spin asymmetry A 1 d and of the deuteron spin-dependent structure function g 1 d at Q 2 1 ( GeV / c ) 2 and 4 × 10 −5 x 2.5 × 10 −2 based on the data collected by the COMPASS experiment at CERN during the years 2002 and 2003. The statistical precision is tenfold better than that of the previous measurement in this region. The measured A 1 d and g 1 d are found to be consistent with zero in the whole range of x.

The Polarised Valence Quark Distribution from semi-inclusive DIS

2007

The semi-inclusive difference asymmetry A^{h^{+}-h^{-}} for hadrons of opposite charge has been measured by the COMPASS experiment at CERN. The data were collected in the years 2002-2004 using a 160 GeV polarised muon beam scattered off a large polarised ^6LiD target and cover the range 0.006 < x < 0.7 and 1 < Q^2 < 100 (GeV/c)^2. In leading order QCD (LO) the asymmetry A_d^{h^{+}-h^{-}} measures the valence quark polarisation and provides an evaluation of the first moment of Delta u_v + Delta d_v which is found to be equal to 0.40 +- 0.07 (stat.) +- 0.05 (syst.) over the measured range of x at Q^2 = 10 (GeV/c)^2. When combined with the first moment of g_1^d previously measured …

Collins and Sivers asymmetries for pions and kaons in muon-deuteron DIS

2008

The measurements of the Collins and Sivers asymmetries of identified hadrons produced in deep-inelastic scattering of 160 GeV/c muons on a transversely polarised 6LiD target at COMPASS are presented. The results for charged pions and charged and neutral kaons correspond to all data available, which were collected from 2002 to 2004. For all final state particles both the Collins and Sivers asymmetries turn out to be small, compatible with zero within the statistical errors, in line with the previously published results for not identified charged hadrons, and with the expected cancellation between the u- and d-quark contributions.

The COMPASS experiment at CERN

2007

The COMPASS experiment makes use of the CERN SPS high-intensitymuon and hadron beams for the investigation of the nucleon spin structure and the spectroscopy of hadrons. One or more outgoing particles are detected in coincidence with the incoming muon or hadron. A large polarized target inside a superconducting solenoid is used for the measurements with the muon beam. Outgoing particles are detected by a two-stage, large angle and large momentum range spectrometer. The setup is built using several types of tracking detectors, according to the expected incident rate, required space resolution and the solid angle to be covered. Particle identification is achieved using a RICH counter and both…

Measurement of the Spin Structure of the Deuteron in the DIS Region

2005

We present a new measurement of the longitudinal spin asymmetry A_1^d and the spin-dependent structure function g_1^d of the deuteron in the range 1 GeV^2 < Q^2 < 100 GeV^2 and 0.004< x <0.7. The data were obtained by the COMPASS experiment at CERN using a 160 GeV polarised muon beam and a large polarised 6-LiD target. The results are in agreement with those from previous experiments and improve considerably the statistical accuracy in the region 0.004 < x < 0.03.

Gluon polarization in the nucleon from quasi-real photoproduction of high-pT hadron pairs

2006

Abstract We present a determination of the gluon polarization Δ G / G in the nucleon, based on the helicity asymmetry of quasi-real photoproduction events, Q 2 1 ( GeV / c ) 2 , with a pair of large transverse-momentum hadrons in the final state. The data were obtained by the COMPASS experiment at CERN using a 160 GeV polarized muon beam scattered on a polarized 6 LiD target. The helicity asymmetry for the selected events is 〈 A ∥ / D 〉 = 0.002 ± 0.019 ( stat ) ± 0.003 ( syst ) . From this value, we obtain in a leading-order QCD analysis Δ G / G = 0.024 ± 0.089 ( stat ) ± 0.057 ( syst ) at x g = 0.095 and μ 2 ≃ 3 ( GeV / c ) 2 .
