On the Son-Yamamoto relation in the soft-wall holographic model of QCD [PDF]
Stefano NicotriWe study the vertex function of two vector and one axial-vector operators in the soft-wall holographic model of QCD. In particular, we discuss the possible relation, introduced by Son and Yamamoto, between the structure function $w_T$ describing such a vertex when one of the two vector currents represents an on-shell soft photon and the the two-point $\Pi_\perp^{VV}-\Pi_\perp^{AA}$ correlation function.View original: http://arxiv.org/abs/1209.1936
