Measurement of the Tau Lepton Polarisation at LEP2

DELPHI Collaboration, J. Abdallah

A first measurement of the average polarisation P_tau of tau leptons produced in e+e- annihilation at energies significantly above the Z resonance is presented. The polarisation is…

Search for Pentaquarks in the Hadronic Decays of the Z Boson with the DELPHI Detector at LEP

The DELPHI Collaboration, J. Abdallah

The quark model does not exclude states composed of more than three quarks, like pentaquark systems. Controversial evidence for such states has been published in the last years, in…

Study of Leading Hadrons in Gluon and Quark Fragmentation

The DELPHI Collaboration, J. Abdallah

The study of quark jets in e+e- reactions at LEP has demonstrated that the hadronisation process is reproduced well by the Lund string model. However, our understanding of gluon fr…

Search for eta_b in two-photon collisions at LEP II with the DELPHI detector

The DELPHI Collaboration, J. Abdallah

The pseudoscalar meson eta_b has been searched for in two-photon interactions at LEP II. The data sample corresponds to a total integrated luminosity of 617 pb^{-1} at centre-of-ma…

Coherent Soft Particle Production in Z Decays into Three Jets

The DELPHI Collaboration, J. Abdallah

Low-energy particle production perpendicular to the event plane in three-jet events produced in Z decays in e+e- annihilation is measured and compared to that perpendicular to the…

A measurement of the branching fractions of the b-quark into charged and neutral b-hadrons

The DELPHI Collaboration, J. Abdallah

The production fractions of charged and neutral b-hadrons in b-quark events from Z0 decays have been measured with the DELPHI detector at LEP. An algorithm has been developed, base…
