Study of Z Pair Production and Anomalous Couplings in $e^+ e^-$ Collisions at $\sqrt{s}$ between 190 GeV and 209 GeV / OPAL Collaboration
A study of Z-boson pair production in e+e- annihilation at center-of-mass energies between 190 GeV and 209 GeV is reported. Final states containing only leptons, (l+l-l+l- and l+l-nn), quark and lepton pairs, (qql+l-, qqnn) and only hadrons (qqqq) are considered. [...]

Measurement of event shape distributions and moments in $e^{+}e^{-} \to$ hadrons at 91-209 GeV and a determination of $\alpha_{s}$ / OPAL Collaboration
We have studied hadronic events from e+e- annihilation data at centre-of-mass energies from 91 to 209 GeV. We present distributions of event shape observables and their moments at each energy and compare with QCD Monte Carlo models. [...]

Measurement of $R_b$ in $e^+ e^-$ Collisions at 182 - 209 GeV / OPAL Collaboration
Measurements of Rb, the ratio of the bbbar cross-section to the qqbar cross- section in e+e- collisions, are presented. The data were collected by the OPAL experiment at LEP at centre-of-mass energies between 182 GeV and 209 GeV. [...]

Determination of the LEP Beam Energy using Radiative Fermion-pair Events, 2004 / OPAL Collaboration
We present a determination of the LEP beam energy using radiative return fermion-pair events recorded at centre-of-mass energies from 183 GeV to 209 GeV. We find no evidence of a disagreement between the OPAL data and the LEP Energy Workings Group's standard calibration [...]

Flavour Independent $h^{0}A^{0}$ Search and Two Higgs Doublet Model Interpretation of Neutral Higgs Boson Searches at LEP / OPAL Collaboration
Upper limits on the cross-section of the pair-production process e+e- -> h0A0 assuming 100% decays into hadrons, are derived from a new search for the h0A0 -> hadrons topology, independent of the hadronic flavour of the decay products. Searches for the neutral Higgs bosons h0 and A0, are used to obtain constraints on the Type II Two Higgs Doublet Model (2HDM(11)) with no CP violation in the Higgs sector and no additional non Standard Model particles besides the five Higgs bosons.

Multi-Photon Events with Large Missing Energy in $e^{+}e^{-}$ Collisions at $\sqrt{s}=192-209 GeV$ / OPAL Collaboration
Events with a final state consisting of two or more photons and large missing transverse energy have been observed in e+e- collisions at centre-of-mass energies in the range 192 - 209 GeV using the OPAL detector at LEP. Cross-section measurements are performed within the kinematic acceptance of the selection and compared with the expectation from the Standard Model process e+e- -> nu nu gamma gamma(gamma). [...]

Search for neutral Higgs bosons in CP-conserving and CP-violating MSSM scenarios / OPAL Collaboration
This report summarizes the final results from the OPAL collaboration on searches for neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM). CP-conserving and for the first time at LEP CP-violating scenarios are studied. [...]

Scaling violations of quark and gluon jet fragmentation functions in $e^{+}e{-}$ annihilations at $\sqrt{s}$ = 91.2 and 183-209 GeV / OPAL Collaboration
Flavour inclusive, udsc and b fragmentation functions in unbiased jets, and flavour inclusive, udsc, b and gluon fragmentation functions in biased jets are measured in e+e- annihilations from data collected at centre-of-mass energies of 91.2, and 183-209 GeV with the OPAL detector at LEP. The unbiased jets are defined by hemispheres of inclusive hadronic events, while the biased jet measurements are based on three-jet events selected with jet algorithms. [...]

Measurement of the Strange Spectral Function in Hadronic $\tau$ Decays / OPAL Collaboration
Tau lepton decays with open strangeness in the final state are measured with the OPAL detector at LEP to determine the strange hadronic spectral function of the tau lepton. The decays T- ->(Kpi)-nu tau, (Kpipi)-nu tau and (Kpipipi) -nu tau with final states consisting of neutral and charged kaons and pions have been studied. [...]
