End-Cap Proportional Tube Chambers for the Upgraded UA2 Experiment
No full textThis paper describes the design and construction of proportional tube chambers used as a tracking and preshower device in the UA2 detector; test beam results and the performance of the chambers at the CERN p-antip collider are describe
Measurement of jet fragmentation properties at the CERN p-antip collider
No full textThe jet fragmentation properties are described: yhe energy flow is compared with different model prediction, the charged particle multiplicity exceeds extrapolations from lower energy jets produced in electron-positron collider
Measurement of jet production properties at the CERN p-antip collider
No full textResults on the total transverse momentum of the jet, on the parton density in the nucleon and on two-jet angular distributions are reported and compared with QCD prediction
Study of electron pairs below the Z mass produced in p-antip collisions at (s)1⁄2 = 540 GeV
No full textEvents with electron pairs below the Z mass has been studied; comparisons are made with the expectation from Drell-Yan mechanism and from semileptonic dacay of heavy flavours
Observation of single isolated electrons of high transverse momentum in events with missing transverse energy at the CERN p-antip collider
No full textWe report the results of a search for single isolated electrons of high transverse momentum: four events with large missing transverse energy has been found whose configuration and number are consistent with the production of W boson predicted by the electroweak theory
Features of coherent neutron diffraction on deuterons at the ISR
No full textResults are reported on the measurement of the differential cross-section for the coherent neutron dissociation on deuterons
Measurement of the Standard Model parameters from a study of W and Z bosons
No full textA study of the 'electronic' decay of W and Z bosons has been made. Measurements of the Standard Model parameters from samples of 251 W decay and 39 Z decay candidates are compared with expectations of electroweak model
Inelastic intermediate states in proton-deuteron and deuteron-deuteron elastic collisions at the ISR
No full textWe present experimental results on proton-deuteron and deuteron-deuteron elastic scattering. In both reactions we find clear evidence
for a substantial contribution of inelastic intermediate states in the multiple-scattering region, as well in single scattering
