1209.1929 (Stefano Nicotri)

Anomalous $AV^*V$ vertex in the soft-wall holographic model of QCD    [PDF]

Stefano Nicotri
We discuss the vertex function of two vector and one axial-vector operators in the soft-wall holographic model of QCD. When one of the two vector currents represents an on-shell soft photon, such a vertex is described by two structure functions $w_L$ and $w_T$, which are usually calculated through triangular loop diagrams. We evaluate these functions in the soft-wall model of holographic QCD (HQCD) and compare the outcome to the QCD findings.
