Whatever they are, magnetic monopoles should be elementary objects,
and should not be capable of any further breakdown in terms of more
elementary particles.

I think that knowledge that
"magentic monopole is half of a gluon"
could be important unknown relation between
electromagnetism and strong interaction ?

There is no data to decide such on.

The basic idea of a monopole is very roughly like so: In order to have
a net source of magnetic field (or sync with the opposite charge)
you have to do something very different from the usual electro-
magnetic field at the particle itself. The usual idea is to suppose
that the electro-magnetic field is the "frozen out" portion of a more
complicated field, and the U(1) symmetry of E&M is all that remains
of a higher symmetry after spontaneous symmetry breaking. With
only the U(1) field, there is no way to have a magnetic field that
is both smooth everywhere, and a net source of magnetic field lines.
(See the "hairy ball" theorm.) But with restored symmetry (at very
short distances from the monopole) you fill in the U(1) circle, and
allow the field to change continuously through other configurations.

The usual way of expressing this is, try to imagine shrinking a
Mobius strip from a finite size to zero size. You can't do it
continously, because the strip always has a "wind" in it, and
that can't go away continuously. But if you "fill in" the allowed
configurations of the mobious strip to be a solid ring, then the
strip is embedded in the larger possible configurations. Instead
of a single line at each point around the loop, you have a disk.
And that allows you to continuously move from having a kink,
to not having a kink. (You have to imagine the edge of the strip
moving around on the surface of a torus.)

However, we don't yet have a good theory of how that would happen.
We don't have a super unification theory that has been confirmed.
So we don't really know if such a particle could exist as a singlet
(that is, a fundamental particle) or would be a member of some
kind of multiplet. We don't know if it should look like an electron
(which sure seems to be fundamental) or a proton (which has
sub-component quarks). It might even be the case that a
monopole could come in both types.

But we don't have any data one way or the other. They might not
even be possible for all we can tell from measurements.

That is not a useful statement. It is a garbled
collection of words jumbled together. It is word salad.

We know the nature of electromagnetism. We know how the
strong force behaves. Neither includes magnetic monopoles.
To get monopoles you need to go outside the behaviour of the
strong and electromagnetic forces.

Read a book. Repeat as required.

You left out a word. Read a _hard_ book, one that makes you think
through exercises that actually have right and wrong answers. Harlequin
Romances don't count.
