Abstract

We present the first numerical solution that corresponds to a pair of Cho-Maison monopoles and antimonopoles(MAPs)in the SU(2)× U(1)Weinberg-Salam(WS)theory.The monopoles are finitely separated,while each pole carries a magnetic charge±4π/e.The positive pole is situated in the upper hemisphere,whereas the negative pole is in the lower hemisphere.The Cho-Maison MAP is investigated for a range of Weinberg angles,0.4675≤tanθw ≤ 10,and Higgs self-coupling,0≤β≤ 1.7704.The magnetic dipole moment(μm)and pole separation(dz)of the numerical solutions are calculated and analyzed.The total energy of the system,however,is infinite due to point singularities at the locations of monopoles.
