  An alternative approach to the Standard Model is outlined, being motivated by
the increasing theoretical and experimental difficulties encountered by this
model, which furthermore fails to be unitary. In particular, the conceptual
uneasiness generated by the excessive multiplicity of fundamental elements of
the Quark Model, 36 different quarks whose cohesion needs 8 different types of
gluons, has logically led some physicists to propose a variety of quark
substructures in an effort to reach unity. In order to avoid the forward escape
corresponding to the attribution of a substructure to quarks and to stand away
from the conceptual strangling to which the Standard model has led, we have
instead opted for different fundamentals. These, in contrast to those of the
Standard Model, are extremely simple and based on the assumption of a single
fundamental corpuscle, of dual manifestation as corpuscle and anticorpuscle, to
which is always associated an orbital that determines the structure of
particles. In such a frame particles differentiate through the diversity of
quantum states of their structuring orbital, in contrast to the strategy used
by the Standard Model based instead on the particle's multiplicity of
composition through the variety of the quark's content, furthermore limited to
hadrons. Instead the orbital conception of particles is unitary, unifying all
of them as well as their interactions. As an outstanding feature, nuclear
forces derive from the neutron orbital structure, based on a proton core and a
shell. This shell constitutes the cohesive element of nuclear structure.
