Research on quantum chromodynamics and quark-gluon plasma sheds light on the "mass"
When the constituents of matter are examined on ever-smaller microscales, ultimately, e arrive at fundamental constituents called elementary particles. Nowadays, a theory of elementary particles has been established; it #39;s called the "standard model." Apart from the gravitational interaction, all interactions -- namely, the electromagnetic, weak, and strong interactions - can be understood in terms of the standard model. Kenji Fukushima #39;s group is doing theoretical research on the strong interaction, which is described using the standard model -- in particular, a theory called quantum chromodynamics. Q "Quantum chromodynamics is a theory that #39;s closely related to quantum electrodynamics, which preceded it. Quantum electrodynamics is the fundamental theory of interaction between electrons and light, or photons, including quantum effects. Quantum chromodynamics is the corresponding, essential theory that describes interactions between quarks and gluons." Quarks and gluons, the basic constituents of matter, can #39;t be measured experimentally, because they can #39;t be extracted individually. This property is called "color confinement." The theoretical proof of color confinement in QCD is still an unsolved problem. It #39;s also one of the Millennium Prize Problems set by the Clay Mathematics Institute. Q "When we consider matter in very special environments - at extremely high temperatures or densities - quarks and gluons become free and [please clarify] physical degrees of freedom of ...From:keiouniversityViews:4 1ratingsTime:03:55More inEducation
