Open Strings and Diquarks Describe Baryon Mass Spectrum
Analysis
This paper proposes a novel approach to understanding hadron mass spectra by applying open string theory. The key contribution is the consistent fitting of both meson and baryon spectra using a single Hagedorn temperature, aligning with lattice-QCD results. The implication of diquarks in the baryon sector further strengthens the connection to Regge phenomenology and offers insights into quark deconfinement.
