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.
