Five-flavor molecular pentaquarks in the Ξ b ( ′ , * ) D ¯ ( * ) and Ξ c ( ′ , * ) B ( * ) systems
Abstract
The discovery of hidden-charm pentaquarks and open-flavor tetraquarks motivates the search for even more exotic hadron configurations. In this work, we investigate genuinely exotic molecular pentaquark candidates comprising five different flavors, focusing on the Ξ b ( ′ , * ) D ¯ ( * ) and Ξ c ( ′ , * ) B ( * ) systems. Employing the one-boson-exchange model with the S − D wave mixing and coupled-channel dynamics, we identify the most promising molecular pentaquark candidates comprising five different flavors. These include the Ξ b D ¯ , Ξ b ′ D ¯ , Ξ c B , and Ξ c ′ B states with I ( J P ) = 0 ( 1 / 2 − ) , the Ξ b D ¯ * , Ξ b ′ D ¯ * , Ξ c B * , and Ξ c ′ B * states with I ( J P ) = 0 ( 1 / 2 − , 3 / 2 − ) , the Ξ b * D ¯ and
