Since its mass is very close to sum of <math><msub><mi>\u03a3</mi><mi>c</mi></msub></math> and <math><mover><mi>D</mi><mo>\u00af</mo></mover></math> masses, it is naturally tempted to be considered as a molecular state composed of <math><msub><mi>\u03a3</mi><mi>c</mi></msub></math> and <math><mover><mi>D</mi><mo>\u00af</mo></mover></math>. Moreover, <math><msub><mi>P</mi><mi>c</mi></msub><mo>(</mo><mn>4312</mn><mo>)</mo></math> is observed in the channel with <math><mi>J</mi><mo>/</mo><mi>\u03c8</mi><mi>p</mi></math> final state, requiring that isospin conservation <math><msub><mi>P</mi><mi>c</mi></msub><mo>(</mo><mn>4312</mn><mo>)</mo></math> is an isospin-<math><mn>1</mn><mo>/</mo><mn>2</mn></math> eigenstate. In the literature, several groups used various models to estimate its spectrum. We systematically study the pentaquarks within the framework of the Bethe-Salpeter equation; thus <math><msub><mi>P</mi><mi>c</mi></msub><mo>(</mo><mn>4312</mn><mo>)</mo></math> is an excellent target because of the available data. We calculate the spectrum of <math><msub><mi>P</mi><mi>c</mi></msub><mo>(</mo><mn>4312</mn><mo>)</mo></math> in terms of the Bethe-Salpter equations and further study its decay modes. Some predictions on other possible pentaquark states that can be tested in future experiments are made."
