The O( 3 s) QCD radiative corrections are also known 11. Large logarithms are resummed by using the running quark mass m Q(M H0) and the strong coupling s(M ) both de ned at the scale M H0. The top quark existence is very short. It decays into a lighter mass b quark and a W boson. The existence of the top quark is inferred by the observation of its decay products. Each W boson also decays shortly after being produced, therefore signatures of top pair production depend on the decay of the two W bosons in the event. The top-quark mass is measured in the all-hadronic top-antitop quark decay channel using proton-proton collisions at a centre-of-mass energy of s=8 TeV with the ATLAS detector at the CERN Large Hadron Collider.

A quark ( / kwɔːrk, kwɑːrk /) is a type of elementary particle and a fundamental constituent of matter.

Reversing the charges for antiquarks gives their triangle (Fig. (1)). The presence of a strange quark in a particle is denoted by a quantum number S=-1. Particle decay by the strong or electromagnetic interactions preserve the strangeness quantum number.

Quarks as we know them are fundamental particles, which means that they do not have smaller constituents. This however does not imply that they cannot decay. A particle in quantum field theory does not need to have constituents to decay into, it can in principle decay into any particle its corresponding field couples to (interacts with), as long as For the big quarks (charm, top, bottom) this is typically thought of as the quark decaying to a lighter state by emitting a lepton pair or a charged meson.

Sanman says something earlier that isn't right: hadronization is NOT quarks decaying "into regular matter" (post #3). This is not the right way to think of it - rather, hadronization is not a decay, but a binding of a quark (or quarks) with other quarks created from the vacuum. The top quark completes the three generation structure of the Standard Model (SM). After QCD jets, W and Z bosons, the production of top quarks is the dominant process in pp collisions at multi-TeV energies: at √ s=7 TeV with an instantaneous luminosity of 1033cm−2s−1, 10 tt¯pairs are produced per minute. In the process illustrated here, the top quark’s final decay products are two jets associated with quarks arising from W boson decay and a single jet from a bottom quark; the antitop quark yields a muon, a neutrino, and a jet from a bottom quark. mesons have a mass of 139.6 MeV/c 2 and a mean lifetime of 2.6033 × 10 −8 s. They decay due to the weak interaction.
