The discovery of the top quark (Conference) | OSTI.GOV.

The classification of baryon and meson states provided by the «quark» model is compared with that offered by the «spinning-top» model, in which the spin is the sum of three vectors the lengths of which determine the strangeness, isospin, baryon parity and mesonG-parity. for the lower lying baryon states and many of the meson states the two models are. Top Quark Spin Correlations - Theory Abstract The top quark decay width (G {sub F}m {sub t} {sup 3} {approx} 1 GeV) is much larger than the QCD hadronization scale ( {Lambda} {sub QCD} {approx} 0.1 GeV) and much larger than the spin decorrelation scale ( {Lambda} {sub QCD} {sup 2}/m {sub t} {approx} 0.1 MeV). His video is of a high performance spinning top.

A number of top-spin observables are computed within the Standard Model (SM), at next-to-leading order in the strong and weak gauge couplings for hadronic top-quark anti-quark (t.

What is a bottom quark? - Stephen Sekula - Physicist.

For single top production through an s-channel W boson, 98 % of the top quarks have their spins in the antiproton direction. For single top production via Wg-fusion, 96 % of the top quarks have their spins in the spectator jet direction. The direction of the top quark spin is reflected in the angular correlations of its decay products.

Did that and things are back to normal. At threshold, top quark pairs are produced in an s-wave. Angular momentum conservation then implies that the top spins equal the spin of the initial state which—in the case of quarks—is uniquely.

The Quark Top is a remarkable spinning top that will spin for over a quarter of an hour powered by a single twist of fingers about 10 times as long as a conventional top. The new nickel plating improves laser reflection for higher accuracy when balancing. The new Quark top retails for $49.95.

The ultra-high performance Quark spinning top uses a tungsten ball pressed into this aluminum cone and spins on a glass surface. Although glass and tungsten do not have very low coefficients of friction their hardness results in a very low contact radius which is an overriding factor.

Top Quark Spin Correlations at the Tevatron (Conference) | OSTI.GOV.

Abstract: A first measurement of the top quark spin asymmetry, sensitive to the top quark polarisation, in t-channel single top quark production is presented. It is based on a sample of pp collisions at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 19.7 inverse-femtobarns. • Heavy quark mesons • The top quarks • EXTRA - Group Theory of Multiplets. 2 Isospin Symmetry... • 1932 - Heisenberg - think of the proton and the neutron as two charge states of the nucleon • In analogy to spin, the nucleon has isospin 1/2 I 3 = 1/2 proton I 3 = -1/2 neutron Q = (I 3 + 1/2) e • Isospin turns out to be a. T tails of the top quark production cross-sections. Section 4 summarizes results on top quark spin correlations. In Section 5, the observability of the inclusive SM top quark charge asymmetry at the 14 TeV LHC is studied as a function of experimental systematic uncertainties. Section 6 summarizes studies for alternate measure.

Each spinning top is 1.4" (3.55 cm) tall and has a diameter of 1.1" (2.8 cm). We found this to be the perfect size for our tops. We have designed each and every one for ergonomics, simplicity and elegance. This is very important, if it is too big it becomes challenging to spin, if you make it very small it becomes very hard to grip, after. Properties of Quarks. The six known quarks are, in order of mass, the down, up, strange, charm, bottom, and top quarks. The up, charm, and top quarks have a positive electric charge, 2/3 of the proton charge, while the other three quarks have a negative charge that is 1/3 of the electron charge.

Mass of Quark. The mass of the neutron is 939.565 MeV/c 2, whereas the mass of the three quarks is only about 10 MeV/c 2 (only about 1% of the mass-energy of the neutron). Like the proton, most of mass (energy) of the neutron is in the form of the strong nuclear force energy (gluons).The quarks of the neutron are held together by gluons, the exchange particles for the strong nuclear force.

A new twist on top quark spin correlations | SpringerLink.

The spin correlations are measured using the angular distributions of the leptons in dilepton channel $\mathrm{t\bar{t}}$ events. The spin correlations are probed both directly, using distributions measured in the top quark rest frames that depend only on the top quark spin, and indirectly, using distributions measured in the laboratory frame.

ATLAS measures the polarisation of top quarks and antiquarks.

Spinless particles (such as Higgs bosons) decay in any direction with equal probability, but particles with spin (such as top quarks) prefer to decay along their axis of spin. When I was asked to write an article on the CMS experiment’s measurement of the spin of the top quark, a metaphor immediately suggested itself: spinning tops. However, the more I thought of. There are 6 different types of quarks known as, up quark, down quark, strange quark, top quark, bottom quark and charm quark. On the other hand, matter is made up of other elemental particles called the ""leptons". Similar to quarks, leptons are also 6 types known as electron, electron neutrino, muon neutrino, muon, tau and tau neutrino. There was a full-blown spin "crisis" in the 1980s when an experiment at the European Center for Nuclear Research (CERN) revealed that the sum of quark and antiquark spins within a proton could.

Unfortunately for my metaphor, the top quark prefers to decay along its spin axis, rather than against it, because the mechanism has nothing to do with centrifugal forces. With a huge sample of top quark decays observed by CMS, physicists selected the 9,000 cleanest events and successfully measured spin-related asymmetries in their decays.
