Alpha thalassemia retardation associated with chromosome16 (ATR-16 syndrome) is defined as a contiguous gene syndrome resulting from haploinsufficiency of the α-globin gene cluster and genes involved in mental retardation (MR). To date, only few cases have been described which result from pure monosomy for a deletion of 16p. In most of these cases the(More)
We present a leading order QCD analysis of a sample of neutrino induced chargedcurrent events with two muons in the final state originating in the lead-scintillating fibre calorimeter of the CHORUS detector. The results are based on a sample of 8910 neutrino and 430 antineutrino induced opposite-sign dimuon events collected during the exposure of the(More)
A search for ! e and  ! e oscillations has been carried out with the CHARM II detector exposed to the CERN wide band neutrino beam. The data were collected over ve years, alternating beams mainly composed of muon-neutrinos and muon-antineutrinos. The number of interactions of e and e observed is comparable with the number of events expected from ux(More)
A precision measurement of the double-differential production cross-section, dσ + /dpdΩ, for pions of positive charge, performed in the HARP experiment is presented. The incident particles are protons of 12.9 GeV/c momentum impinging on an aluminium target of 5% nuclear interaction length. The measurement of this cross-section has a direct application to(More)
We report our final results from the analysis of the full high statistics sample of events of the reaction up + e--+ /*+ v, collected with the CHARM II detector in the CERN wide-band neutrino beam during the years 1988 to 1991. From a signal of 15 758 f 324 inverse muon decay events we derived, in the Born approximation, a value of ( 16.51 f 0.93) x lO-42(More)
The double-differential production cross-section of positive pions, dσ + /dpdΩ, measured in the HARP experiment is presented. The incident particles are 8.9 GeV/c protons directed onto a beryllium target with a nominal thickness of 5% of a nuclear interaction length. The measured cross-section has a direct impact on the prediction of neutrino fluxes for the(More)
The final oscillation analysis of the complete set of data collected by CHORUS in the years 1994–1997 is presented. Reconstruction algorithms of data extracted by electronic detectors were improved and the data recorded in the emulsion target were analysed by new automated scanning systems, allowing the use of a new method for event reconstruction in(More)
We built and tested on charged particle beams the high energy-resolution calorimeter for the CHORUS experiment, which searches for νμ-ντ oscillations in the CERN Wide Band Neutrino beam. This calorimeter is longitudinally divided into three sectors: one electromagnetic and two hadronic. The first two upstream sectors are made of lead and plastic(More)
We report new limits on the production of muonic photons in the CERN neutrino beam. The results are based on the analysis of neutrino production of dimuons in the CHARM II detector. A 90% CL limit on the coupling constant of muonic photons, = < (1:5 3:2) 10 6 is derived for a muon neutrino mass in the range m = (10 20 10) eV. This improves the limit(More)
In the HARP experiment the large-angle spectrometer is using as main tracking and particle identification detector a cylindrical TPC. The momentum scale of reconstructed tracks in the TPC is the most important systematic error for the majority of kinematic bins used for the HARP measurements of the double-differential production cross-section of charged(More)
