Significats de z boson en anglès

This occurs because the mass of the Z boson is 91 GeV.

And anyway, what about the W and Z bosons?

The discovery of higher-mass W and Z bosons would shed important new light on these interactions.

These are heavier versions of the W and Z bosons, which are responsible for weak interactions.

The reason for the difference is the mass of the W and Z bosons, which carry the weak force.

We report the first evidence of Z boson pair production at a hadron collider with a significance exceeding 4 standard deviations.

So for four-lepton masses below twice this mass -182 GeV -the Z bosons cannot have their most probable mass.

One of the ways the Higgs boson can decay is to two Z bosons, which then decay to two leptons each.

Events with two oppositely charged electrons or muons, consistent with coming from the decay of a Z boson, and jets are investigated.

They just get close, and then the neutrino transfers a tiny bit of energy to a neutral particle called a Z boson.

Charged-particle distributions, excluding the lepton-antilepton pair from the Z-boson decay, are measured in different ranges of transverse momentum of the Z boson.

We select events with a final state composed of a W or Z boson and a jet consistent with a heavy object decay.

Event-shape observables measured using charged particles in inclusive Z-boson events are presented, using the electron and muon decay modes of the Z bosons.

Direct searches for lepton flavour violation in decays of the Higgs and Z bosons with the ATLAS detector at the LHC are presented.

The third is a fixed-order calculation with next-to-next-to-leading order accuracy for the process with a Z boson and one parton in the final state.

Events with a hadronic jet with the jet mass consistent with a W or Z boson, and with large missing transverse momentum are analyzed.
