Moreover, it is found that the states with parity¥P= (°1)jare degenerate with the states with parity¥P= (°1)j+1if the Lorentz structure of the interaction between the masslessconstituents is four-vector or time-component of four-vector. The scalar interaction violates this degeneracy. 2016 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57045452009 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
