Weinberg sum rules at NLO in 1/Nc
J. J. Sanz-Cillero, J. Trnka
We study the relevance of different renormalization schemes in Resonance Chiral Theory. The SS-PP correlator is explicitly computed at the one-loop level. Demanding the operator pr…

High energy constraints in the octet SS-PP correlator and resonance saturation at NLO in 1/Nc
J. J. Sanz-Cillero, J. Trnka
We study the octet SS-PP correlator within resonance chiral theory up to the one-loop level, i.e., up to next-to-leading order in the 1/Nc expansion. We will require that our corre…
