    • n dissociation The severance of association or connection; separation; disunion.
    • n dissociation Specifically In chem., the resolution of more complex into simpler molecules by the action of heat. Also called thermolysis. Dissociation is applied by some authors to cases where the dissociated gases recombine when the temperature falls, and thermolysis where the gases do not spontaneously recombine on cooling. Also disassociation.
    • n dissociation In psychology: The disjunction of an associative connection, as by lapse of memory or by intercurrent associations, by the selective process of active attention, etc.
    • n dissociation A minor degree of the disintegration or disaggregation of consciousness, as it is termed, which culminates in the phenomena of dual or multiple personality.

In science:

If the same object (e.g. a gluon ladder) is exchanged in proton dissociative and elastic scattering, proton vertex factorisation should be manifest through the Q2 independence of the cross section ratio for t = 0.
