Very high energy neutrino expectation from Fanaroff-Riley I sources
  Fanaroff-Riley I radiogalaxies have been observed in TeV gamma-rays during
the last decades. The origin of the emission processes related with this energy
band is still under debate. Here we consider the case of the two closest
Fanaroff-Riley I objects: Centaurus A and M87. Their entire broadband spectral
energy distributions and variability fluxes show evidences that leptonic models
are not sufficient to explain their fluxes above 100 GeV. Indeed, both objects
have been imaged by LAT instrument aboard of Fermi telescope with measured
spectra well connected with one-zone leptonic models. However, to explain the
TeV spectra obtained with campaigns by H.E.S.S., for Centaurus A, and by
VERITAS, MAGIC and H.E.S.S. for M87, different emission processes must be
introduced. In this work we evoke hadronic scenarios to describe the TeV
gamma-ray fluxes observed and to obtain the expected neutrino counterparts for
each considered TeV campaign. With the obtained neutrino spectra we calculate,
through Monte Carlo simulations, the expected neutrino event rate in a
hypothetical Km$^{3}$ neutrino telescope and we compare the results with what
has been observed by IceCube experiment up to now.
