Investigation of the photoproduction of bottom-charmed baryons within NRQCD

We present a further theoretical study of the orbital P -wave bottom-charmed baryon within the framework of nonrelativistic QCD, considering both the direct photoproduction channel γ + γ → Ξ b c + c ¯ + b ¯ and the resolved photoproduction channel γ + g → Ξ b c + c ¯ + b ¯ . At future linear colliders, ILC and CLIC, the initial photons can be emitted from the laser backscattering and then the parton gluon can be emitted from the photon. The formation of Ξ b c can be modeled in two steps: a compact diquark state ⟨ b c ⟩ [ n ] is formed first and subsequently captures a light quark from the vacuum to hadronize into the baryon Ξ b c . The color and spin quantum number [ n ] of the ⟨ b c ⟩ diquark can be [ S 3 1 ] 3 ¯ / 6 , [ S 1 0 ] 3 ¯ / 6 , [ P 1 1 ] 3 ¯ / 6 , or [ P
