Charmed ${\bf (70,1^-)}$ baryon multiplet

Understand

The masses of negative parity $(70,1^-)$ charmed nonstrange baryons are calculated in the relativistic quark model.

• The relativistic three-quark equations of the $(70,1^-)$ charmed baryon multiplet are found in the framework of the dispersion relation technique.
• The approximate solutions of these equations using the method based on the extraction of leading singularities of the amplitude are obtained.
• The calculated mass values of the $(70,1^-)$ charmed baryons are in good agreement with the experimental data.
