In this paper, we investigate the relation between the twist field, which represents string interactions in matrix string theory, and the three-string interaction vertex in light-cone string field theory carefully. We find that the three-string interaction vertex can reproduce some of the most important OPEs satisfied by the twist field.19 pages, 3 figures, LaTeX2e; v2: minor corrections, a reference addedHigh Energy Physics - Theorytext
