  Centaurus B (Cen B) is one of the closest and brightest radio-loud galaxy in
the southern sky. This radio galaxy, proposed as a plausible candidate for
accelerating ultra-high-energy cosmic rays (UHECRs), is near the highest-energy
neutrino event reported (IC35) in the High-Energy Starting Events catalog.
Pierre Auger observatory reported the highest energy comic rays during 10 years
of collecting data with some of them around this source. In this paper, the
analysis of the gamma-ray spectrum and the light curve above 200 MeV is
presented with nine years of cumulative Fermi-LAT data around Cen B. Taking
into consideration the multi-wavelength observations carried out about this
radio galaxy, leptonic and hadronic scenarios are introduced in order to fit
the spectral energy distribution, assuming that the gamma-ray flux is produced
in a region close to the core and in the extended lobes. Using the best-fit
values found, several physics properties of this radio galaxy are derived.
Furthermore, a statistical analysis of the cosmic ray distribution around Cen B
is performed, finding that this distribution is not different from the
background at a level of significance of 5%. Considering the UHECR event
associated to this source by Moskalenko et al. and extrapolating its luminosity
to low energies, we do not find enough evidence to associate the highest-energy
neutrino event (IC35) with this radio galaxy.
