Regge slopes in dual topological expansion

Tan, Chung-I

“…It is well known that an HES can be described as random walk of interactions [53]- [58], and than one can measure the precise microstates structure of the spatial distribution of HES studying the effective horizon, for example, probed in HES Compton-like scattering processes. Implementing random surface techniques [59]- [63] to the HES form factors one can obtain a complementary picture of the HES nature where chaotic and thermal effects can be matched with the effective HES horizon governed by the superposition of microstates. We leave this investigation for future works.…”

We analyse the most general process of a generic highly excited string that decays into a less excited, yet generic, highly excited string emitting a tachyon. We provide a simple and compact analytic description of the decay process which discriminates between and within the structure of every single microstate of the initial and final highly excited string. Taking into account the random nature of the decay process we extract the energy spectrum of highly excited strings, microstate by microstate, finding a behavior which corresponds to the greybody emission spectrum. In addition, by exploiting the analytic control of the decay process, we identify the origin of thermal effects which are triggered by the chaotic nature of the highly excited string interactions modeled by the microstates structure.

We study a bootstrap model of inclusive reactions based on dual-topological-unitarization diagrams of the multi-Regge type. By applying the bootstrap equations developed for the multifireball model, we are able to calculate the branching process of the dual multi-Regge chain, keeping longitudinal-momentum conservation exactly. We calculate various single-particle spectra in pion, kaon, and proton fragmentation. These spectra are compared with experimental data.
