Hybrid Quarkonia on Asymmetric Lattices
PACS Collaboration, T. Manke, H. P. Shanahan +15
We report on a study of heavy hybrid states using the NRQCD approach on coarse and asymmetric lattices, where we discard vacuum polarisation effects and neglect all spin-correction…
A Measurement of Rb using a Double Tagging Method
The OPAL Collaboration, G. Abbiendi et al
The fraction of Z to bbbar events in hadronic Z decays has been measured by the OPAL experiment using the data collected at LEP between 1992 and 1995. The Z to bbbar decays were ta…
Quenched Light Hadron Spectrum with the Wilson Quark Action: Final Results from CP-PACS
PACS Collaboration, S. Aoki, G. Boyd +13
We report the final results of the CP-PACS calculation for the quenched light hadron spectrum with the Wilson quark action. Our data support the presence of quenched chiral singula…
Full QCD light hadron spectrum from the CP-PACS
PACS Collaboration, S. Aoki, G. Boyd +13
We report on an on-going two-flavor full QCD study on CP-PACS using an RG-improved gauge action and a tadpole-improved SW quark action. Runs are made for three lattice spacings $a^…
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…
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…
An upper limit on the anomalous magnetic moment of the τlepton
The OPAL Collaboration, K. Ackerstaff et al
Using radiative Z^0 -> τ^+ τ^- γevents collected with the OPAL detector at LEP at \sqrt{s}= M_Z during 1990-95, a direct study of the electromagnetic current at the τγvertex has be…
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…
