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.

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.

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 ...

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.

Quest for the Origin of Particles and the Universe, 2007
Cosmology is in the midst of a period of revolutionary discovery, propelled by bold ideas from particle physics and by technological advances from gigapixel charge-coupled device cameras to peta-scale computing. The basic features of the universe have now been determined: It is 13.7 billion years old, spatially flat, and expanding at an accelerating ...

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.

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.

We are used to thinking of quarks as fundamental particles in the same way we think of the electron, or gauge bosons, neutrinos, leptons. In strong theory, these objects are unified with gravitation and the physics of spacetime into what is hoped to be an ultimate theory, string/M theory.

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.
