Abstract

In this article, the explicit P-wave of the Λ_cΛ_c dibaryon states with the J^PC=0^-± and 1^-± 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 P-wave could be neglected. The numerical results of the masses of the P-wave Λ_cΛ_c are high above the threshold of the two Λ_c and Λ_c baryon constituents, Λ_c and Λ_c are unlikely to form the bound molecules with explicit P-wave . Pole residues of the related states are also calculated.
