The global fit of the Standard Model predictions to electroweak precision data, which has
been routinely performed in the past decades by several groups, led to the prediction of the …

We review the status of precision measurements of weak neutral-current interactions,
mediated by the Z 0 boson, at Q 2≪ M 2 Z. They can be used to extract values for the weak …

This biennial Review summarizes much of particle physics. Using data from previous
editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average …

We consider the small excesses around 95 GeV found in several searches for a new scalar
in γ γ, τ τ, and bb¯ final states. Instead of trying to accommodate them all, as is usually done …

The ATLAS detector at the Large Hadron Collider is used to search for high-mass
resonances decaying to dielectron or dimuon final states. Results are presented from an …

A bstract We perform a detailed study of the dark Z′ portal using a generic parametrization
of the Z′-quarks couplings, both for light (8-15) GeV and heavy (100-1000) GeV dark matter …

We discuss the prospects for setting limits on or discovering spin-1 Z′ bosons using early
LHC data at 7 TeV. Our results are based on the narrow width approximation in which the …

We study extensions of the Standard Model with general new vector bosons. The full
Standard Model gauge symmetry is used to classify the extra vectors and constrain their …

We considerminimal'Z'models, whose phenomenology is controlled by only three
parameters beyond the Standard Model ones: the Z'mass and two effective coupling …

A bstract We study the framework of U (1) X models with kinetic mixing and/or mass mixing
terms. We give general and exact analytic formulas of fermion gauge interactions and the …
