Neutrino production in jetted AGN is linked to hadronic proc esses such as photomeson production. The same interaction predicts also high-energy photo ns, mostly via neutral pion decay. While neutrinos escape the source unattenuated, the hadron ically produced high-energy photons and pairs initiate pair cascades in most cases which re-dist ribute their energy to lower frequencies where photons can escape the emission region. Realistic had ronic emission models of AGN jets take into account competing energy losses of injected/acce lerat d particles as well as all leptonic processes (owing to primary and secondary electrons). This may smear out any intrinsic correlation between emerging photon and neutrino fluxes. This work r epo ts on an investigation about the degree of observable photon-neutrino flux and luminosit y correlations that is expected from hadronic AGN jet emission models. For this purpose the expec ted neutrino spectra from a number of hadronically modeled broadband spectral energy distrib utions (SEDs) of powerful blazars is calculated and compared to the photon fluxes at various frequ encies by means of a correlation analysis. The results have implications for the search of th e photon sources that are associated to the TeV-PeV neutrino events reported by neutrino observato ies.
