bottom quark

The scientists, who (http://lhcb-public.web.cern.ch/lhcb-public/Welcome.html#RKstar) studied a particle called B meson (which is a class of hadrons containing a bottom quark), found an "intriguing" anomaly in the way it decays.

The top quark decays to a W boson and either a bottom quark (most frequently), a strange quark, or a down quark (rarely).

The study of Kobayashi and Maskawa was substantiated by the discoveries of the charm quark in 1974 (8) and the bottom quark in 1977.

Each chromatic pentad also contains three matrices corresponding to three coordinates and two mass matrices--one for top quark and another--for bottom quark.

Leon Lederman and colleagues report evidence of a new quark, the bottom quark, in experiments at Fermilab (8/13/77, p.

The unmatter does exists, for example some messons and antimessons, through for a trifling of a second lifetime, so the pions are unmatter (which have the composition u^d and ud^, where by u^ we mean anti-up quark, d = down quark, and analogously u = up quark and d^ = anti-down quark, while by ^ means anti), the kaon [K.sup.+] (us^), [K.sup.-] (u^s), Phi ([ss^), [D.sup.+] (cd^), [D.sup.0](cu^), [D.sup.+.sub.s] (cs^), J/Psi (cc^), [B.sup.-] (bu^), [B.sup.0] (db^), [B.sup.0.sub.s] (sb^), Upsilon (bb^), where c = charm quark, s = strange quark, b = bottom quark, etc.

He asserted that the particle comprises a bottom quark and a bottom anti-quark.

The pair of quarks expected from the Higgs--a bottom quark and its antimatter partner- would in turn decay into jets of still other particles visible to the Tevatron.

The newly discovered Xi-sub-b ([[XI].sup.o.sub.b]) contains a strange quark, an up quark and a bottom quark.

After starting to work on 30 March, one of LHC's four large detectors detected evidence of a beauty quark - also, less poetically, known as a bottom quark - on 5 April.

Because the two accelerators hunt for the Higgs in different ways--the Tevatron would detect the proposed particle's most common decay products, a bottom quark and its antiparticle, while the Large Hadron Collider would record a rarer decay mode that produces two photons--the searches are not only competitive but complementary.
