“…The experimental results of the PLUTO collaboration from 1978 favored a charge of Q = −1/3 [33]. Measurements of the angular distribution of b hadrons produced in e + e − collision supported the quantum numbers I 3 = −1/2 and Q = −1/3 for the bottom quark [34], strongly suggesting that the bottom quark is the down-type quark of the third generation whose I 3 = +1/2 isospin partner was yet to be discovered.…”

After the discovery of the top quark more than 20 years ago, its properties have been studied in great detail both in production and in decay. Increasingly sophisticated experimental results from the Fermilab Tevatron and from Run 1 and Run 2 of the LHC at CERN are complemented by very precise theoretical predictions in the framework of the standard model of particle physics and beyond. In this article the current status of top-quark physics is reviewed, focusing on experimental results, and a perspective of top-quark physics at the LHC and at future colliders is given.

“…Using these variables and the various correlations between them, it was possible to distil out a sample of about 270 b-quark events which allowed an angular distribution to be measured. The angular distribution thus obtained [9] is shown in Figure 9.…”

“…Since the b-quark was the fifth to be observed and the other four are apparently already paired into doublets, this implies that a sixth quark, the t, must exist to pair up with the b. I shall finish with the relevant quotation from the 1996 Review of Particle Physics [lo]. "The existence of a sixth quark has been expected since the discovery of the bottom quark itself and has become a theoretical necessity within the Standard Model after the measurement of the T3=-1/2 weak isospin of the bottom quark [9]. "…”

“…Moreover, the weak isospin of the b quark was measured, via angular asymmetries in e + e − → bb production, to be T3 = −1/2 [37], suggesting a doublet structure similar to that for the lighter generations. 4 'Parity' refers to the quantum mechanical operator that inverts a spatial displacement vector, i.e., r → −r.…”

Bound states of heavy quarks can serve as a laboratory for inquiry into the behaviour of the fundamental strong and electroweak interactions. This thesis examines observations of B 0 , B 0 , and B ± mesons produced in proton-antiproton collisions at centre-of-mass energies of √ s = 1.8 TeV. The B-meson decay products are recorded using the Collider Detector at Fermilab (CDF) located on the Tevatron collider at the Fermi National Accelerator Laboratory in Batavia, Illinois, USA.Four B-meson decays and their charge conjugates are studied: The indicated uncertainties are statistical and systematic, respectively. In ratios involving unlike B-meson species, equal production rates for B + and B 0 mesons have been assumed.Absolute branching fractions are extracted by normalizing the above ratio measurements to the world-average value, B(B + → J/ψ K + ) = (1.01 ± 0.14) × 10 −3 :
