Description
We review the status of transverse single-spin asymmetries (SSAs) A_N in proton-proton collisions within the collinear twist-3 framework. We use newly derived constraints from Lorentz invariance relations, along with previously known equation of motion relations, to rewrite A_N in terms of a maximum number of so-called kinematical functions, which are weighted integrals of TMD functions. From this, we are able to give an estimate for the SSA using known TMD inputs and provide constraints on the lesser known so-called dynamical (multi-parton) correlators.
