Search for Anomalous Photonic Events with Missing Energy in e+e- Collisions at Ecm = 130, 136 and 183 GeV

The OPAL Collaboration, G. Abbiendi et al

Photonic events with large missing energy have been observed in e+e- collisions at centre-of-mass energies of 130, 136 and 183 GeV collected in 1997 using the OPAL detector at LEP.…

A Study of Parton Fragmentation in Hadronic Z0 Decays Using Lambda-Lambdabar Correlations

The OPAL Collaboration, G. Abbiendi et al

The correlated production of Lambda and Lambdabar baryons has been studied using 4.3 million multihadronic Zo decays recorded with the OPAL detector at LEP. Di-lambda pairs were in…

Measurement of the Average Polarization of b Baryons in Hadronic Z^0 Decays

The OPAL Collaboration, G. Abbiendi et al

In the Standard Model, b quarks produced in e^+e^- annihilation at the Z^0 peak have a large average longitudinal polarization of -0.94. Some fraction of this polarization is expec…

Production of pi+, K+, K0, K*0, phi, p and Lambda-0 in Hadronic Z0 Decays

The SLD Collaboration, K. Abe

We have measured the differential production cross sections as a function of scaled momentum x_p=2p/E_cm of the identified hadron species pi+, K+, K0, K*0, phi, p, Lambda0, and of…

Search for Stable and Long-Lived Massive Charged Particles with the OPAL Detector at LEP in e+e- Collisions at \sqrt{s}=130-183 GeV

The OPAL Collaboration, K. Ackerstaff et al

A search for stable and long-lived massive particles of electric charge |Q/e| = 1 or 2/3, pair-produced in e+e- collisions at centre-of-mass energies from 130 to 183 GeV, is report…

A Search for Neutral Higgs Bosons in the MSSM and Models with Two Scalar Field Doublets

The OPAL Collaboration, K. Ackerstaff et al

A search is described for the neutral Higgs bosons h^0 and A^0 predicted by models with two scalar field doublets and, in particular, the Minimal Supersymmetric Standard Model (MSS…
