In what condition can the 125 GeV Higgs boson decay to a pair of on-shell W-bosons?

TL;DR

This paper explores the theoretical possibility of a 125 GeV Higgs boson decaying into an on-shell W-boson pair within extremely strong magnetic fields, revealing new decay channels under such conditions.

Contribution

It demonstrates that in a magnetic field of about 10^23 G, the Higgs boson can decay into W-boson pairs, a process not possible without such fields, expanding understanding of Higgs decay modes.

Findings

Decay into W-boson pairs becomes possible in magnetic fields ~10^23 G.

A new neutral boson with J=0 and different mass range is not excluded.

The decay channel depends on energy and angular momentum conservation laws.

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 ~10^23 G (or in Teslas ~10^19 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 2m_W=160.77 GeV.
