The correlation between the top and antitop quark spins is extracted from dilepton tt¯ events by using the difference in the azimuthal angle between the two charged leptons in the laboratory frame. In the helicity basis the measured degree of correlation corresponds to Ahelicity=0.38±0.04, in agreement with the standard model prediction.

Top is a most remarkable particle, even for a quark. Although a single top quark weighs about as much as an atom of gold, we expect that it is structureless down to a scale of at least 10-18 m.

Frame 4: A top and antitop quark emerge from the gluon cloud. Frame 5: These quarks begin moving apart, stretching the color force field (gluon field) between them. Frame 6: Before the top quark and antiquark have moved very far, they decay into a bottom and antibottom quark (respectively) with the emission of W force carrier particles.

The antiparticle of the top quark is the top antiquark (symbol: t, sometimes called antitop quark or simply antitop), which differs from it only in that some of its properties have equal magnitude but opposite sign. The top quark interacts with gluons of the strong interaction and is typically produced in hadron colliders via this interaction.

However, these protons and neutrons are constructed from only 2 of the 12 known quarks, being up quarks and down quarks. There are 12 main types of quarks, being split into 6 particles made of matter and 6 particles made of antimatter, with each of these halves being split into three 'generations'. Here is a list of the 12 known kinds of A top–antitop quark pair can be produced from the collision of energetic protons and antiprotons. A quark from the proton annihilates an antiquark from the antiproton, and according to the celebrated E = mc 2 formula, the energy E released by the annihilation … The CMS collaboration saw evidence of top quarks in a large data sample from lead–lead collisions at an energy of 5.02 TeV. The team searched for collisions producing a top quark and a top antiquark.

If one of these particles exists with a mass of a few TeV then it may be produced during proton-proton collisions at the Large Hadron Collider (LHC). The analysis presented in this thesis searches 36 fb−1 of √s = 13 TeV proton- proton collision data collected by the products of the top (antitop) quark times the longitudinal polarization of the top (antitop) quark and C represents the t t spin correlation. The angle 1 ( 2) corresponds to the polar angle of the nal state decay product used to determine 1 P 1 ( 2 P 2) of the top (antitop) quark. Quarks are the building blocks of protons and neutrons. However, these protons and neutrons are constructed from only 2 of the 12 known quarks, being up quarks and down quarks.

This allowed ATLAS to detect and measure an unprecedented number of events involving top-antitop quark pairs, providing ATLAS physicists with a unique opportunity to gain insight into the top quark’s properties. 2021-02-19 Instead, top quarks are produced preferentially in the centre of the LHC's collisions, while antitop quarks are produced preferentially at larger angles. This is known as a "charge asymmetry ." Mar 2, 2017 - The ANTITOP QUARK antiparticle to the Top Quark. Also part of the Antiquark 6-pack and Antiparticle 14-pack.

The hadron events are evidence of quark production. The ratio of the number of hadron events to the number of muon events gives a measure of the number of "colors" of the quarks, and the evidence points to five quarks with three colors. Measurements of spin correlation in top quark pair production are presented using data collected with the ATLAS detector at the LHC with proton-proton collisions at a center-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 4.6 fb-1 .
