OBJECTIVE Since 1987, psychosocial services have been a part of the primary care setting in Germany. In the framework of an eight-center national demonstration program, problems in the diagnosis and therapy of psychosocial problems and psychosomatic disorders were assessed. Methods to improve quality were also implemented. METHOD General practitioners (n(More)
This Technical Design Report is dedicated to Tom Ypsilantis. Tom conceived the Ring Imaging Cherenkov detectors for particle identification in LHCb and he made an inestimable contribution to the LHCb RICH project. Tom would have wished to see these detectors in operation. He was totally dedicated to the project. He will be missed by the RICH group for his(More)
The four-jet nal state is analyzed to search for hadronic decays of pair-produced heavy particles. The analysis uses the ALEPH data collected at LEP in November 1995 at centre-of-mass energies of 130 and 136 GeV, corresponding to a total integrated luminosity of 5.7 pb ?1. An excess of four-jet events is observed with respect to the standard model(More)
The T' state has been observed as a narrow resonance at M(T') = 10.02-+ 0.02 GeV in e+e-annihilations, using a NaI and lead-glass detector in the DORIS storage ring at DESY. The ratio PeeFhad/Ftot of electronic, hadronic, and total widths has been measured to be 0.32 +-0.13 keV. The parameters of the ~" particle have also been determined to beM(T) = 9.46 +_(More)

Using the data accumulated at LEP in 1989 and 1990 with the ALEPH detector, the inclusive and exclusive branching ratios of the r lepton have been measured assuming lepton universality in Z ~ decays. The inclusive branching fractions for the r decay into one, three, and five charged particles have been determined to be (85.45 _+ 0.97)%, (14.35 _+ 0.48)%,(More)
A lower limit is set on the B 0 s meson oscillation parameter m s using data collected from 1991 to 1994 by the ALEPH detector. Events with a high transverse momentum lepton and a reconstructed secondary vertex are used. The high transverse momentum leptons are produced mainly by b hadron decays, and the sign of the lepton indicates the(More)
The ATLAS SemiConductor Tracker (SCT) is a silicon-strip tracking detector which forms part of the ATLAS inner detector. The SCT is designed to track charged particles produced in proton-proton collisions at the Large Hadron Collider (LHC) at CERN at an energy of 14 TeV. The tracker is made up of a central barrel and two identical end-caps. The barrel(More)
From approximately 3 million hadronic decays of Z bosons recorded with the aleph detector at lep, a sample of 410 32 B 0 ! D + ` ? ` candidates is selected, wherè is either an electron or a muon. The diierential decay rate d?(B 0 ! D + ` ? `)=d! from this sample is tted, yielding a value for the product of the CKM matrix element jV cb j and the(More)
Four-fermion events have been selected in a data sample of 5.8 pb ?1 collected with the aleph detector at centre-of-mass energies of 130 and 136 GeV. The nal states`+`? q q, ` + ` ? ` + ` ? , q q, and`+`? have been examined. Five events are observed in the data, in agreement with the Standard Model predictions of 6:67 0:38 events from four-fermion processes(More)
DEPFET pixels offer a unique possibility for a high resolution pixel vertex detector as the innermost component of the tracking system in the TESLA detector. DEPFET pixels excel in comparison to other pixel detectors in the simultaneous achievement of high spatial, energy and time resolution even at room temperature operation. In the DEPFET pixel scheme the(More)
