Tensor-polarized structure function $b_1$ in the standard convolution description of the deuteron

Understand

Tensor-polarized structure functions of a spin-1 hadron are additional observables which do not exist for the spin-1/2 nucleon.

• They could probe novel aspects of the internal hadron structure.
• Twist-2 tensor-polarized structure functions are $b_1$ and $b_2$, and they are related by the Callan-Gross-like relation in the Bjorken scaling limit.
• In this work, we theoretically calculate $b_1$ in the standard convolution description for the deuteron.
