Symmetry nonrestoration at high temperature and the monopole problem

    Research output: Contribution to journalArticlepeer-review


    We show that there exists a range of parameters in SU(5) theory for which the grand unified theory symmetry remains broken at high temperature, thus avoiding the phase transition that gives rise to the overproduction of monopoles. The thermal production of monopoles can be naturally suppressed, keeping their number density below the cosmological limits.
