Probing the weak boson sector in e + e - →W + W -
TL;DR: In this paper, a detailed analysis of W pair production in e+e− annihilation at LEP-II energies is presented by using helicity amplitudes for the process e−e−→W+W− with arbitrary WWγ and WWZ couplings.

Muon anomalous magnetic moment: A harbinger for ''new physics''
TL;DR: In this article, the status and implications of the recently reported 2.6 sigma experiment versus theory deviation a{sub {mu}}{sup expt}-a{sub{mu}{sup SM}=426(165) x 10{sup -11} are discussed.

The self-couplings of vector bosons : does LEP-1 obviate LEP-2?
TL;DR: In this paper, the authors analyze the constraints on two generic types of meta-theory, in which fundamental scalar do or do not exist, and illustrate the current strictures by focusing on the allowed range of departures from the most crucial, untested, precise standard prediction: the size and structure of the triple gauge-boson vertices.

Low-energy constraints on electroweak three gauge boson couplings
TL;DR: In this paper, the authors consider one-loop effects induced by the dimension-six operators (D ω Φ) √ gT i W i ων (D ν Φ ) and gG − gYB √ G − g − Φ √ YB ωγ ) and show that such effects at most logarithmically divergent, as required by decoupling, imply modest constraints on the size of new physics signals.

Uses and abuses of effective Lagrangians
C.P. Burgess,David London +1 more
TL;DR: It is proved that the inclusion of nonlinearly realized gauge invariance into the low-energy Lagrangian is irrelevant to this conclusion and that many calculations, such as those involving anomalous trilinear gauge-boson couplings, either considerably overestimate loop-induced effects or give ambiguous answers.

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.

TL;DR: In this paper, a search for electron pairs produced in p p collisions at s = 550 GeV was carried out, and it was reported that eight events which were interpreted as resulting from the process p +p→Z 0 + anything, followed by the decay Z0→e++e− or Z 0→e−e−+γ, where Z0 is the neutral Intermediate Vector Boson postulated by the unified electroweak theory.
