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…
Search for Scalar Top and Scalar Bottom Quarks at sqrt(s) = 183 GeV at LEP
The OPAL Collaboration, K. Ackerstaff et al
Searches for a scalar top quark and a scalar bottom quark have been performed using a total data sample of 56.8 pb-1 at a centre-of-mass energy of 183 GeV collected with the OPAL d…
Search for Higgs Bosons and New Particles Decaying into Two Photons at sqrt(s) = 183 GeV
The OPAL Collaboration, K. Ackerstaff et al
A search for the resonant production of high mass photon pairs associated with a leptonic or hadronic system has been performed using a data sample of 57.7 pb-1 collected at an ave…
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…
Measurements of Flavour Dependent Fragmentation Functions in Z^0 -> qq(bar) Events
The OPAL Collaboration, K. Ackerstaff et al
Fragmentation functions for charged particles in Z -> qq(bar) events have been measured for bottom (b), charm (c) and light (uds) quarks as well as for all flavours together. The r…
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…
Production of f_0(980), f_2(1270) and ϕ(1020) in hadronic Z^0 decay
The OPAL Collaboration, K. Ackerstaff et al
Inclusive production of the f_0(980), f_2(1270) and ϕ(1020) resonances has been studied in a sample of 4.3 million hadronic Z^0 decays from the OPAL experiment at LEP. A coupled ch…
