Title: Quark van der Waals forces

Journal Article · · Phys. Rev., D; (United States)

The possibility of long-range forces between quark which are constituents of different hadrons is considered, in analogy to the Van der Waals forces between electrically neutral atoms. The two-virtual-gluon-exchange force, implied by quantum chromodynamics, can be estimated and is uninterestingly small even if there exist rather low-lying color-octet hadrons. If there are Van der Waals--type forces associated with a quark-confining potential, then there may arise a conflict with the experimentally well determined one-pion-exchange tail of the nuclear force unless any color-octet baryons lie very high in energy. This condition is not met in the model in which the confining potential arises from the small-k singularity of ''dressed'' one-gluon exchange.
