  The recent data by the TOTEM Collaboration on $\sigma_{tot}$ and $\rho$ at 13
TeV, have shown agreement with a leading Odderon contribution at the highest
energies, as demonstrated in the very recent analysis by Martynov and Nicolescu
(MN). In order to investigate the same dataset by means of Pomeron dominance,
we introduce a general class of forward scattering amplitude, with leading
contributions even under crossing, associated with simple, double and triple
poles in the complex angular momentum plane. For the lower energy region, we
consider the usual non-degenerated Regge trajectories, with even and odd
symmetry. The analytic connection between $\sigma_{tot}$ and $\rho$ is obtained
by means of dispersion relations and we carry out fits to $pp$ and $\bar{p}p$
data in the interval $\sqrt{s}=5$ GeV - 13 TeV; following MN we consider only
the TOTEM data at the LHC energy region. From the fits, we conclude that the
general analytic model, as well as some particular cases representing standard
parameterizations, are not able to describe satisfactorily the $\sigma_{tot}$
and $\rho$ data at 13 TeV. Further analyses in course and some perspectives are
outlined.
