Effective Functional Form of Regge Trajectories

TL;DR

This paper argues that hadronic Regge trajectories are inherently nonlinear and can be effectively modeled using a specific square-root functional form, supported by theoretical reasoning and phenomenological evidence.

Contribution

It introduces a particular square-root form for Regge trajectories, providing a new phenomenological model supported by theoretical and empirical evidence.

Findings

Regge trajectories are nonlinear in nature.

A specific square-root form accurately approximates these trajectories.

The model is supported by strong phenomenological evidence.

Abstract

We present theoretical arguments and strong phenomenological evidence that hadronic Regge trajectories are essentially nonlinear and can be well approximated, for phenomenological purposes, by a specific square-root form.
