QCD does not distinguish between quark flavours, onlycolourcharge of quarks matters. At high energy (E ≫binding energy of quarks within hadrons), ratio of σ(pp) total and σ(π+p) total depends on number of possible quark-quark combinations. Predict: Experiment: σ(πp) σ(pp) = 2 ×3 3 ×3 = 2 3 σ(πp) σ(pp) = 24 mb 38 mb ∼ 2 3 Prof ...
20 wrz 2018 · Here we show that the phase structure of such strongly interacting matter can be decoded by analysing particle production in high-energy nuclear collisions within the framework of statistical ...
10 gru 2020 · Between baryons, the strong interaction leads to a residual force and the most common example is the effective strong force among nucleons (N)—baryons composed of up (u) and down (d) quarks: proton...
26 lut 2020 · Abstract. The strong nuclear interaction between nucleons (protons and neutrons) is the effective force that holds the atomic nucleus together. This force stems from fundamental interactions...
Through the strong interaction, gluons bind quarks into groups according to quantum chromodynamics (QCD), forming hadrons such as protons and neutrons. Gluons carry the color charge of the strong interaction, thereby participating in the strong interaction as well as mediating it.
Quarks carry colour charge and form bound systems of colourless mesons and baryons by the exchange of coloured gluons. This interaction leads to scaling violations, i.e., the dependence of the structure functions on the momentum transfer, that are proportional to the strong coupling constant α s .
At the most fundamental level, the strong force is an exchange force between quarks mediated by gluons. The use of Feynman diagrams to visualize the strong interaction involves primitive vertices with quarks and gluons.
