nLab Regge trajectory

Idea

In physics, specifically in quantum hadrodynamics and in string theory, a Regge trajectory is, for any given type of physical system but specifically for hadrons and for strings, the graph of the mass-squared as a function of total angular momentum (with all other properties held fixed).

Properties

Hadron supersymmetry

The Regge trajectories of mesons and of hadrons are observed to have essentially the same slope.

from BTDL 16

This phenomenon is explained by hadron supersymmetry.
