Resumen:
Our observable universe is said to be (3+1)-dimensional. However, it’s believed
that certain properties observed in nature may be the result of extra dimensions, almost
as an “invisible inheritance”. Among such properties are the flavors numbers and mass
hierarchies of the fundamental fermions (quarks and leptons). With this in mind, studying
the relation that our universe could have with those extra dimensions may be a way of
better understanding the natural properties that surround us. This idea lead us to the
Theory of Super Strings, which, among other things, proposes the existence of a (9+1)-
dimensional universe, where we would be inserted. Knowing this, we propose here a
phenomenological analysis of the fermions in junctions of domains walls. Where these
junctions are mechanisms that make up a dimensional reduction method, which allows us
to obtain our observable (3+1)-dimensional universe from a (9+1)-dimensional universe,
while we looking for degrees of freedom, energies, and decays involving fermions living in
these domain walls.
