Meanings of top quark in inglés

Upper bounds are also set on couplings of the top quark to new light particles.

The top quark was first discovered in 1995 by the Tevatron accelerator, operated by Fermilab in Illinois.

When I was in grad school, the big question was: What is the mass of the top quark?

The first observation of the associated production of a single top quark and a W boson is presented.

A measurement of the top quark mass is reported in events containing a single top quark produced via the electroweak t channel.

The W+b-jets process poses a significant background in measurements of top quark production and prominent searches for the Higgs boson.

We make an event by event estimate of the mass difference to construct templates for top quark pair signal events and background events.

A measurement of the top quark pair production cross section in the final state with a hadronically decaying tau lepton and jets is presented.

The top quark is the heaviest of them all, so we have to look for him at high energies, but he must be there.

There's only about a 0.07 percent chance that the top quark's apparent directional preference is a fluke, Amidei notes.

These results provide the most stringent limits to date on the production of scalar LQs that decay to a top quark and a t lepton.

This paper presents a direct measurement of the decay width of the top quark using t t ¯ events in the lepton+jets final state.

We present a search for a new particle T' decaying to a top quark via T' → t + X, where X goes undetected.

Top quark production in the forward region in proton-proton collisions is observed for the first time.

This highlights the potential of measurements using boosted top quarks, where the new technique will enable future precision measurements.
