Significados de b quark en inglés

Events with two leptons and a jet originating from a b quark are selected.

In this mode each t(1) decays into a tau lepton and a b quark.

Then in July 1977 there was another "sudden discovery", made at Fermilab: this time of a particle based on the b quark.

The search is performed in the three b quark channel using multijet triggered events corresponding to an integrated luminosity of 1 fb(-1).

Such a particle appears in extensions of the standard model, where a light CP-odd Higgs boson naturally couples strongly to b quarks.

Lower limits at 95% confidence level are placed on the masses of the T and B quarks for a range of branching fractions.

Data recorded by the D0 experiment at the Fermilab Tevatron Collider are analyzed to search for neutral Higgs bosons produced in association with b quarks.
