Nuclear Physics A, 1982
Abstract The fundamental role of the pion in nuclear physics is stressed. In bosonexchange models, not only does the pion furnish the longest-range part of the interaction, but the σ-, ρ- and ω-mesons, which give the intermediate and shortrange parts of the interaction, are connected with two-and three-pion states.

The Emergence of Quarks/Anti-Quarks
Hyperscience International Journals, 2022In clarifying the entirety of the universe, the most important processes are the emergence of the universe and the formation of quarks/anti-quarks. The entirety of the universe has emerged in a causal and consecutive manner. According to the Standard Model, from the dawn of the universe, particles such as 3 pairs of neutrinos (v_µ ⁄ v ̅_µ , v_e ⁄ v ̅

Duality in the quark-quark scattering
Il Nuovo Cimento A, 1984The duality constraint in the quark-quark scattering is examined on the basis of the favourSU3 ⊗ colourSU3 algebra. The dominance of the flavour singlet and colour octet exchange implies the equal-weight formation of the flavour sextet and the flavour antitriplet diquarks. The effect to the polarized electroproduction is briefly investigated.

International Journal of Modern Physics A, 2015
A short history of the physics of strongly interacting particles is presented. Events leading to the discovery, and eventual acceptance, of concrete quarks are described. (Other aspects of quark history are given in Refs. 1 and 2.)

Computing in Science & Engineering, 2004
Over the past 25 years (1979-2004), the theoretical-particle physicists who practice lattice-gauge theory have become some of the most frequent users of supercomputing cycles. Although we've long known that atoms consist of electrons surrounding a nucleus made of nucleons (protons and neutrons), we've recently learned that at a deeper level, the ...

Nature, 1986
Because nucleons are bound states of quarks, nuclear matter should at sufficiently high density become a quark plasma. Assuming quantum chromodynamics as the basic theory of nuclear forces, it is possible to derive strong-interaction thermodynamics and study the nature of this transition.

AIP Conference Proceedings, 1982
A brief discussion of the relevance of quark degrees of freedom in Nuclear Physics is presented. Pertinent aspects of bag models of baryons are reviewed, and a six‐quark bag model study of the reaction pp→dπ+ is made.
