Phenomenological constraints on A _{N} in p ^{↑} p → π X from Lorentz invariance relations
Here, we present a new analysis of A _{N} in p ^{↑} p → πX within the collinear twist3 factorization formalism. We incorporate recently derived Lorentz invariance relations into our calculation and focus on input from the kinematical twist3 functions, which are weighted integrals of transverse momentum dependent (TMD) functions. Particularly, we use the latest extractions of the Sivers and Collins functions with TMD evolution to compute certain terms in AN . Consequently, we are able to constrain the remaining contributions from the lesser known dynamical twist3 correlators.
