In a recent paper, Cho, Kim and Yoon (CKY) have proposed a version of the
SU(2) × U(1) Standard Model with finite-energy monopole and dyon
solutions. The CKY model postulates that the effective U(1) gauge coupling →∞ very rapidly as the Englert-Brout-Higgs vacuum expectation value →0, but in a way that is incompatible with LHC measurements of the Higgs boson
H→γγ decay rate. We construct generalizations of the CKY model
that are compatible with the H→γγ constraint, and calculate
the corresponding values of the monopole and dyon masses. We find that the
monopole mass could be <5.5 TeV, so that it could be pair-produced at the
LHC and accessible to the MoEDAL experiment.Comment: 15 pages; Two clarifying footnotes (3 and 4) added. No effect on
