Abstract

In this article, the explicit PwaveP-wave of the ΛˉcΛc\bar{\Lambda}_c\Lambda_c dibaryon states with the JPC=0±J^{PC}=0^{-\pm} and 1±1^{-\pm} are studied via twelve interpolated currents. Results show that the positive and negative charge conjugations for the studied states do not have too much difference, the contribution of the gluon from covariant derivative of the current with PwaveP-wave could be neglected. The numerical results of the masses of the PwaveP-wave ΛˉcΛc\bar{\Lambda}_c\Lambda_c are high above the threshold of the two Λˉc\bar{\Lambda}_c and Λc\Lambda_c baryon constituents, Λˉc\bar{\Lambda}_c and Λc\Lambda_c are unlikely to form the bound molecules with explicit PwaveP-wave . Pole residues of the related states are also calculated.
