Effects of Negative Energy Components on N and Δ Spectra

  • Institute of High Energy Physics, The Chinese Academy of Sciences, Beijing, China

Abstract: By means of the instantaneous Bethe-Salpeter equation, the effect of negative energy components of the Dirac spinor on the one-gluon exchange interaction is studied. Through the calculation of the N and Δ baryon spectra. One sees that the inclusion of the negative-energy components changes the potential parameters significantly, especially for αs. However the global structure of the spectrum is almost untouched.
