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…
The Charge Collection Properties of CVD Diamond
Ties Behnke, Petra Hüntemeyer, Alexander Oh +3
The charge collection properties of CVD diamond have been investigated with ionising radiation. In this study two CVD diamond samples, prepared with electrical contacts have been u…
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…
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…
Measurements of the B^0_s and Λ_b Lifetimes
The OPAL Collaboration, K. Ackerstaff et al
This paper presents updated measurements of the lifetimes of the B^0_s meson and the Λ_b baryon using 4.4 million hadronic Z^0 decays recorded by the OPAL detector at LEP from 1990…
