Experimental observation of isolated large transverse energy electrons with associated missing energy at $\sqrt s$ = 540 GeV
Abstract We report the results of two searches made on data recorded at the CERN SPS Proton-Antiproton Collider: one for isolated large- E T electrons, the other for large- E T neutrinos using theExpand

Experimental observation of lepton pairs of invariant mass around 95 GeV/c2 at the Cern SPS collider
Abstract We report the observation of four electron-positron pairs and one muon pair which have the signature of a two-body decay of a particle of mass ∼ 95 GeV/c2. These events fit well theExpand

Charged particle multiplicity distributions in proton-antiproton collisions at 540 GeV centre of mass energy
Abstract Results on charged particle production in pp collision at s 1 2 = 540 GeV are presented. The data were obtained at the CERN pp collider using the UA1 detector, operated without magneticExpand

Experimental observation of events with large missing transverse energy accompanied by a jet or a photon (S) in pp collisions at s = 540 GeV
Abstract We report the observation of five events in which a missing transverse energy larger than 40 GeV is associated with a narrow hadronic jet and of two similar events with a neutralExpand

Measurement of the inclusive jet cross section at the CERN pp collider
Abstract The inclusive jet cross section has been measured in the UA1 experiment at the CERN p p Collider at centre-of-mass energies √s = 546 GeV and √s = 630 eV. The cross sections are found to beExpand

Transverse momentum spectra for charged particles at the cern proton-antiproton collider
We have measured transverse momentum spectra up to 10 GeV/c for charged particles produced centrally in proton-antiproton collisions at 540 GeV in the centre of mass at the CERN collider. Our resultsExpand

Associated production of an isolated large-transverse-momentum lepton (electron or muon) and two jets at the Cern $p\bar p$ collider
Abstract A clear signal is observed for the production of an isolated large-transverse-momentum lepton in association with two or three centrally produced jets. The two-jet events cluster around theExpand

Observation of jets in high transverse energy events at the CERN proton antiproton collider
Abstract With a segmented total absorption calorimeter of large acceptance, we have measured the total transverse energy spectrum for pp collisions at s 1 2 = 540 GeV up to ΣE T = 130 GeV in theExpand

Intermediate-Vector-Boson Properties at the CERN Super Proton Synchrotron Collider
The properties of a sample of 172 charged intermediate vector bosons decaying in the (eνe) channel and 16 neutral intermediate vector bosons decaying in the (e+e-) channel are described. Masses,Expand
