TLDR
In this paper, the cross section for e+e− → hadrons from a scan around the Z0 pole was determined, based on 4350 hadronic events collected over seven energy points between 89.26 and 93.26 GeV, and a total decay width of 2.60±0.13 GeV.

Astrophysical methods to constrain axions and other novel particle phenomena

TL;DR: In this article, the authors review the theoretical methods as well as the observational data that have been employed in order to use stars as "particle physics laboratories" in the spirit of this argument.

Precision LEP data, supersymmetric GUTs and string unification

TL;DR: In this article, the precision of sin 2 θ MS w (m z ) extracted from LEP data (0.233±0.001) confirms the prediction of minimal supersymmetric GUTs within the errors of about 2%.

Quarks and Leptons Beyond the Third Generation

TL;DR: The possibility of additional quarks and leptons beyond the three generations already established is discussed in this paper, with the possibility of exceptionally long lifetimes and decay modes being dependent on the mass spectrum and mixing angles.

Weak Interactions with Lepton-Hadron Symmetry

TL;DR: In this paper, a model of weak interactions was proposed in which the currents are constructed out of four basic quark fields and interact with a charged massive vector boson, and it was shown that the leading divergences do not violate any strong-interaction symmetry.

Experimental observation of lepton pairs of invariant mass around 95 GeV/c2 at the Cern SPS collider

David B. Cline, +132 more
- 07 Jul 1983 - 
TL;DR: In this paper, the signature of a two-body decay of a particle of mass ∼ 95 GeV/c2 was observed, which fit well with the hypothesis that they are produced by the process p + p → Z 0 + X (with Z 0 → l + + + l − ), where Z 0 is the Intermediate Vector Boson postulated by the electroweak theories as the mediator of weak neutral currents.

Monte Carlo simulation of general hard processes with coherent QCD radiation

TL;DR: In this paper, the authors extended their previous work on the simulation of coherent soft-gluon radiation to hard collisions that involve incoming as well as outgoing coloured partons, and proposed a new Monte Carlo program which incorporates this procedure, together with other new features such as azimuthal correlations due to gluon polarization and interference.
