Could Λ̅c and Λc form bound hadronic molecule with explicit P−wave ?
Abstract
In this article, the explicit P−wave of the Λ̅cΛc dibaryon states with the JPC=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 Λ̅cΛc are high above the threshold of the two Λ̅c and Λc baryon constituents, Λ̅c and Λc are unlikely to form the bound molecules with explicit P−wave . Pole residues of the related states are also calculated.
