By higher-spin (HS) field one means generalizations of the
electromagnetic potential or of the metric fluctuation that
transform under arbitrary representations of the Lorentz group.
Conceptual difficulties have long been identified in attempts to
couple massless higher-spin modes in a Minkowski background.
However, the key classic no-go theorems typically do not apply in
the presence of infinite numbers of them. String Theory clearly
leads the way to date, since its spectra involves a plethora of
massive HS modes, however, a key question is whether String Theory
itself is part of a more general structure for higher-spin
interactions, and what role it possibly plays in it. For massive
fields, one expects that an effective Lagrangian description be
possible below the scale of their masses, and therefore in this
Thesis String Theory is taken as a starting point to exhibit for
the first time a number of couplings involving higher-spin modes.
The novelty is here the explicit computation of tree-level
scattering amplitudes for massive modes. The Weyl calculus allows
to present the whole set of cubic and quartic string couplings and
the resulting currents in a suggestive form.
