Sl. Carbon et Cb. Thorn, INTERPRETATION OF HIGH-ENERGY STRING SCATTERING IN TERMS OF STRING CONFIGURATIONS, Physical review. D. Particles and fields, 49(12), 1994, pp. 6264-6268
High energy string scattering at fixed momentum transfer, known to be
dominated by Regge trajectory exchange, is interpreted by identifying
families of string states which induce each type of trajectory exchang
e. These include the usual leading trajectory alpha(t) = alpha't + 1 a
nd its daughters as well as the ''sister'' trajectories alpha(m)(t) =
alpha(t)/m - (m - 1)/2 and their daughters. The contribution of the si
ster alpha(m) to high energy scattering is dominated by string excitat
ions in the mth mode. Thus, at large -t, string scattering is dominate
d by wee partons, consistent with a picture of the string as an infini
te composite system of ''constituents'' which carry zero energy and mo
mentum.
