Remarks on quark-quark and quark-antiquark potentials
Physical Review D, 1982The quark-quark potential in antisymmetrical color states and the quark-antiquark potential in color-singlet states are given to the fourth order in perturbative quantum chromodynamics. We have also corrected an error involving the charge conjugation of color matrices in our recent derivation of the quark-antiquark potential for arbitrary color states.

Quark-Quark Interaction and the Nonrelativistic Quark Model
Physical Review Letters, 1980This Letter demonstrates that the nonrelativistic approximation breaks down for the lighter hadrons with the conventional $\mathrm{qq}$ one-gluon exchnage potential. This is mainly due to the Coulomb and the short-range hyperfine interactions. To overcome this difficulty, some phenomenological interactions with a long-range spin dependence are proposed.

Frontiers in Bioscience, 2002
Elementary subcellular Ca2+ signals arising from the opening of single ion channels may offer the possibility to examine the stochastic behavior and the microscopic chemical reaction rates of these channel proteins in their natural environment. Such an analysis can yield detailed information about the molecular function that cannot be derived from ...

Screening of the quark-quark interaction
Soviet Physics Journal, 1988We calculate the screening of a linearly increasing quark-quark potential in a many-quark system and explore whether such a system can form a condensate of the Cooper type.

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 ...
