Side-chain theory


  • Webster's Revised Unabridged Dictionary
    • Side-chain theory (Physiol. Chem) A theory proposed by P. Ehrlich as a chemical explanation of immunity phenomena. In brief outline it is as follows: Animal cells and bacteria are complex aggregations of molecules, which are themselves complex. Complex molecules react with one another through certain of their side chains, but only when these side chains have a definite correspondence in structure (this accounts for the specific action of antitoxins).

In science:

On the string theory side it means that the light-cone quantized worldsheet sigma model is an integrable quantum field theory, while on the gauge theory side integrability manifests itself in the appearance of spin chains.
Discrete Hirota dynamics for AdS/CFT
On the gauge theory side, the reason for this breakdown is the appearance of wrapping corrections coming from contributions of Feynman graphs which encompass the whole size of the spin chain.
Discrete Hirota dynamics for AdS/CFT
On the other hand, at the gauge theory side the integrability is exhibited as identification between dilatation operator of N = 4 SYM and Hamiltonian of a integrable spin chain[9, 10] (see the review and references therein).
