A spin 1/2 particle is represented by a spinor while its position is represented by a three-vector. What object should we use to represent such particle if we want to consider both features? That is, what object should we use if we want to consider both spin and space position?
It seems there's not a obvious way to make a product between a spinor and a three-vector.
