Quantized tension: Stringy amplitudes with Regge poles and parton behavior

TL;DR

This paper introduces a novel approach to stringy hadronic amplitudes that unify Regge behavior and parton scattering features by summing over string amplitudes with varying tension and trajectories.

Contribution

It presents a method to combine Regge poles and parton behavior in string amplitudes through summation over trajectories with different tensions, maintaining discrete poles.

Findings

Achieves both Regge soft-scattering and parton hard-scattering behaviors.

Maintains discrete poles in momentum and angular momentum.

Demonstrates convergence with integer tension and intercepts.

Abstract

We propose stringy hadronic amplitudes that combine some of the features of sister trajectories and running tension. By summing over string amplitudes with varying Regge trajectories that have integer tension and converging intercept, we obtain parton hard-scattering and Regge soft-scattering behaviors, while preserving discrete poles in both momentum and angular momentum.
