Arbitrary Four String Scattering at High Energy and Fixed Angle

We calculate, using the group theoretic approach to string theory, the tree and one loop scattering of four open and closed arbitrary bosonic string states. In the limit of high energy, but fixed angle, the multi-string vertex at tree and one loop levels that we find takes a very simple form. We propose, and present arguments for, a form for the high energy multi-string vertex at all loops. Our...

High-energy quark-antiquark elastic scattering with mesonic exchange.

We studied the high energy elastic scattering of quark anti-quark with an exchange of a mesonic state in the t channel with −t/Λ 2 ≫ 1. Both the normalization factor and the Regge trajectory can be calculated in PQCD in cases of fixed (non-running) and running coupling constant. The dependence of the Regge trajectory on the coupling constant is highly non-linear and the trajectory is of order o...

Inverse scattering problem with fixed energy and fixed incident direction

Let A q (α ′ , α, k) be the scattering amplitude, corresponding to a local potential q(x), x ∈ R 3 , q(x) = 0 for |x| > a, where a > 0 is a fixed number, α ′ , α ∈ S 2 are unit vectors, S 2 is the unit sphere in R 3 , α is the direction of the incident wave, k 2 > 0 is the energy. We prove that given an arbitrary function f (α ′) ∈ L 2 (S 2), an arbitrary fixed α 0 ∈ S 2 , an arbitrary fixed k ...

The Connection between Regge Behavior and Fixed Angle Scattering

The physical origins and dynamical details of Regge behavior are studied by examining a general class of theories which are capable of describing the observed large momentum transfer data and extending them into the intermediate t-range. The mechanism responsible for the smooth connection between the deep scattering region and the Regge region is discussed in detail. We derive a convenient new ...
