Abstract

Abstract Our study focuses on the Λ-type P-wave bottom baryon states with spin-parity

. We introduce an explicit P-wave between the two light quarks in the interpolating currents (these light quarks are antisymmetric in the flavor space, thus giving rise to the designation of Λ-type baryon) to investigate the

and

states within the framework of the full QCD sum rules. The predicted masses show that

and

could be the P-wave bottom-strange baryon states with spin-parity

and

, respectively; meanwhile,

and

could be the P-wave bottom baryon states with spin-parity

and

, respectively. Moreover,

and

may have two remarkable under-structures or Fock components at least.
