Modifications to the Hadronic Regge Trajectories

TL;DR

This paper analyzes how quark mass influences Regge trajectories, showing linearity in mesonic systems and non-linearity in baryonic systems, with implications for hadron mass and angular momentum relationships.

Contribution

It introduces modifications to Regge trajectory equations accounting for quark mass effects in mesonic and baryonic systems, highlighting differences in their linearity.

Findings

Mesonic Regge trajectories remain linear despite modifications.

Baryonic Regge trajectories become non-linear with quark mass effects.

Different quark compositions can produce hadrons with identical mass and angular momentum.

Abstract

The effect of quark mass on the Regge trajectory is analysed. Modifications in the equations of Regge trajectories are shown for mesonic as well as baryonic systems. For mesonic systems, the Regge trajectories get modified, but still remain linear. Contrary to the mesonic case, the Regge trajectories for baryonic systems indicate non-linearity. It is shown that in low mass and angular momentum region two hadrons with different quark compositions can have same mass and angular momentum.
