Factorization of the string amplitudes provides a uniform understanding of the $*_N$-products and a hint to obtain a simple, explicit formula (in the momentum space) for arbitrary N in the non-Abelian case. Possible extension to a more general ${}_M *_{N}$-product in the M-loop context is discussed.", "revisions": [ { "version": "v2", "updated": "2000-12-04T09:49:07.000Z" } ], "analyses": { "keywords": [ "factorization", "open strings", "d-brane world-volume", "one-loop effective action" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
