摘要：

In a recent paper, Cho, Kim and Yoon (CKY) have proposed a version of the SU(2) x U(1) Standard Model with finite-energy monopole and dyon solutions. The CKY model postulates that the effective U(1) gauge coupling -> infinity 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 -> gamma gamma decay rate. We construct generalisations of the CKY model that are compatible with the H -> gamma gamma constraint, and calculate the corresponding values of the monopole and dyon masses. We find that the monopole mass could be <5.5TeV, so that it could be pair-produced at the LHC and accessible to the MoEDAL experiment. (C) 2016 The Authors. Published by Elsevier B.V.
