In what condition can the 125 GeV Higgs boson decay to a pair of on-shell W-bosons?
Abstract
We have determined that the decay of the neutral boson at a mass around 125 GeV into an on-shell W-W+-pair in a uniform magnetic field becomes, in principle, possible and the new decay channel of this boson in a magnetic field is allowed by the energy and total angular momentum conservation laws. The required magnetic field strength for observation of the measurable effect is ~1023 G (or in Teslas ~1019 T). The existence of the other neutral boson with the spin J=0 and with the other mass is not either excluded in the mass range below 2mW=160.77 GeV.
