Form-factors and current correlators: chiral couplings L_10(mu) and C_87(mu) at NLO in 1/N(C)

Pich, Antonio; Rosell, Ignasi; Sanz-Cillero, Juan José

ArXiv subject: High Energy Physics - Phenomenology (hep-ph). | Using the resonance chiral theory Lagrangian, we perform a calculation of the vector and axial-vector two-point functions at the next-to-leading order (NLO) in the 1/N(C) expansion. We have analyzed these correlators within the single-re...
