Abstract: (Elsevier)
The monopoles of the unified SU(5) gauge theory broken down to H E = SU(3) c ⊗ U(1) EM [or to K E = SU(3) c ⊗ SU(2) ⊗ U(1) Y ], are classified. They belong to representations of a magnetic group H M (K M ), which is found to be isomorphic to H E (K E ). For SU(5) broken down to H E , there exists a regular and stable monopole which is a colour magnetic triplet, and carries a non-zero abelian magnetic charge. It is suggested that composite operators made out of this monopole and its antiparticle fields develop a non-zero vacuum expectation value, and so lead to a squeezing of the colour electric flux. Finally, we comment on the cosmological production of SU(5) monopoles.
