Limits on the mass and lifetime of long-lived heavy leptons
No full textA beam dump experiment was performed in the CERN Gargamelle neutrino facility in order to look for new heavy penetrating neutral particles. Limits are determined for the mass and lifetimes of such particles , and the cross-section for their productio
Observation of elastic hyperon production by antineutrinos
No full textThe production of Lamda and Sigma0 hyperons by antineutrinos has been observed: the results are compared with the Cabibbo theory
High energy electronic neutrino (νe ) and antineutrino (νe ) interactions
No full textThe total cross-sections for neutrino(e) (antineutrino(e))-nucleon scattering have been measured
Observation of neutrino-like interactions without muon or electron in the Gargamelle neutrino experiment
No full textEvents induced by neutral particles and producing hadrons, but no muons or electrons, have been observed in the Gargamelle neutrino experiment at CERN. These events behave as expected if they arise from neutral current induced processe
Measurement of the neutrino-nucleon and antineutrino-nucleon total cross-sections
No full textThe neutrino and antineutrino nucleon total cross-sections have been determined as a function of energy
Parameterization of e and gamma initiated showers in the NOMAD lead-glass calorimeter
No full textA description of the response of the NOMAD electromagnetic calorimeter to electrons and photons is discussed. In
particular, the dependence of the two-dimensional shower shape on the angle and energy of the incident particle is
parametrized by analytical functions. Some applications to the neutrino event reconstruction are also reported
Search for elastic muon-neutrino electron scattering
No full textOne possible event of the process antinu(mu)-electron scattering has been observed. The various background processes are discussed and the event is interpreted in terms of the Weinberh theory
Experimental study of structure functions and sum rules in charge-changing interactions of neutrinos and antineutrinos on nucleons
No full textThe differential cross-section of inclusive charge-changing neutrino and antineutrino interactions on nucleon have been determined. The observed quark and antiquark momentum distributions are compatible with the predictions of quark-parton model
Observation of neutrino-like interactions without muon or electron in the Gargamelle neutrino experiment
No full textEvents induced by neutral particles and producing hadrons, but no muons or electrons, have been observed in the Gargamelle neutrino experiment at CERN. These events behave as expected if they arise from neutral current induced processe
