Sentences with phrase «z bosons»

Thus, CMS presents the best measurement at the LHC of the weak - mixing angle, a key parameter of the Standard Model that establishes a firmly predicted relation between the masses of the W and Z bosons.

To do that, they studied the decay of the Higgs into familiar particles, such as a pair of photons or a pair of massive particles called Z bosons.

Up to now, researchers have been able to fully prove the decay into other particles — so - called W and Z bosons, photons and tau leptons.

It is some 10 quadrillion times bigger than the mass of the W and Z bosons that define the strength of the weak nuclear force, for example.

The latest results from the ATLAS detector at the LHC suggest that when we look at its decay into two photons, we find that the new boson's mass is about 3 gigaelectronvolts greater than when calculated from its decay into particles called Z bosons.

Unlike a heavy Higgs, a light Higgs rarely decays into Z bosons, and its more common decay products are even more easily lost in the background.

The Higgs is not detected directly, but via the things it decays into, such as pairs of photons or particles called Z bosons.

And the Higgs is entirely responsible for the mass of some particles, notably the W and Z bosons that transmit the weak nuclear force.

Peter Higgs suggested that a mass - giving Higgs field pervades all space, in order to explain why the W and Z bosons have mass but the photon, another boson, doesn't.

• While the text in our «Instant expert» pull - out guide to dark matter (5 February) said that the Z boson transmits the weak nuclear force, the caption on p iv said otherwise.

Instead of studying the decays of the Higgses, they looked for signs of a Higgs produced in tandem with a Z boson or a W boson, particles that convey the weak nuclear force, as they explain in a paper in press at Physical Review Letters.

The second is one called the Z» (pronounced «Z - prime»), a lighter cousin of the Z boson that carries the weak nuclear force.

The ATLAS collaboration also releases first evidence for an important but rare weak - interaction process in which a single top quark is produced together with a Z boson.

The W and Z boson serve as a good model for this kind of exotic stuff: In fact they are both very heavy compared to their peers and interact weakly with ordinary matter.

Not exact matches

In today's version of the electroweak theory, the W and Z particles and all the fundamental constituents — quarks and leptons — get their masses by interacting with the Higgs boson.

«If there is a Higgs boson whose mass is less than that of the Z particle, physicists will discover it over the next two years at the large accelerator in Geneva known as LEP (the Large Electron Positron collider).
