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
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
Measurement of W and Z properties at the CERN p-antip collider
No full textA study of W and Z properties has been performed: the results are compared with the predictions of the electroweak theory
Direct photon production at the CERN p-antip collider
No full textThe inclusive cross-section has been measured for production of high transverse momentum photons; the results are in good agreement with QCD predictions
Measurement of W and Z production properties at CERN p-antip collider
No full textA study has been made of the production characteristics of W and Z bosons: production cross-sections, longitudinal and transverse momentum distributions, associated jet production.These measurements are compared with theoretical expectations which includes high order QCD effects
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
Search for exotic processes at the CERN p-antip collider
No full textLimits on various hypothetical processes, such as production of excited electrons, additional vector bosons, supersymmetric particle
Study of electron pair production below the Z mass at the CERN p-antip collider
No full textResults on the cross-section for the production of electron pairs below the Z mass are presented: they are compared with theoretical calculations which include QCD contributions
