We have measured the mass of Z boson to be 91.14±0.12 GeV/c2, and its width 2.42+0.45−0.35 GeV. If we constrain visible standard-model value, find partial invisible decay modes 0.46±0.10 GeV, corresponding 2.8±0.6 neutrino species, with a 95%-confidence-level upper limit 3.9.Received 12 October 1989DOI:https://doi.org/10.1103/PhysRevLett.63.2173©1989 American Physical Society

Multihadronic e+e− annihilation events at a center-of-mass energy of 29 GeV have been studied with both the original (PEP 5) Mark II and upgraded detectors. Detector-corrected distributions from global shape analyses such as aplanarity, Q2-Q1, sphericity, thrust, minor value, oblateness, jet masses, inclusive charged-particle including x, rapidity, p⊥, particle flow are presented. These compared predictions various multihadron event models which use leading-logarithmic shower evolution or...

At the Large Hadron Collider (LHC), absolute luminosity calibrations obtained by van der Meer (vdM) method are affected mutual electromagnetic interaction of two beams. The colliding bunches experience relative orbit shifts, as well optical distortions akin to dynamic-$\beta$ effect, that both depend on transverse beam separation and must therefore be corrected for when deriving scale. In vdM regime, beam-beam parameter is small enough shift can calculated analytically. corrections...

The strong coupling αs(M2Z) has been measured using hadronic decays of Z0 bosons collected by the SLD experiment at SLAC. data were compared with QCD predictions both fixed order O(α2s) and including resummed analytic formulas based on next-to-leading logarithm approximation. In this comprehensive analysis we studied event shapes, jet rates, particle correlations, angular energy flow, checked consistency between values extracted from these different measures. Combining all results obtain...
