Particle decay in false vacuum
We revisit the problem of decay of a metastable vacuum induced by the presence of a particle. For the bosons of the 'master field' the problem is solved in any number of dimensions in terms of the spontaneous decay rate of the false vacuum, while for a fermion we find a closed expression for the decay rate in (1+1) dimensions. It is shown that in the (1+1) dimensional case an infrared problem o...
متن کاملCan Cosmic Ray Catalysed Vacuum Decay Dominate Over Tunnelling?
We consider the question of whether cosmic ray catalysed false vacuum decay can be phenomenologically more important than spontaneous decay via quantum tunnelling. We extend the zero bubble wall width Landau-WKB analysis of catalysed false vacuum decay to include the leading order effects of finite wall width and derive an expression for the thin-wall bubble action. Using this we calculate the ...
متن کاملCatalyzed decay of a false vacuum in four dimensions.
The probability of destruction of a metastable vacuum state by the field of a highly virtual particle with energy E is calculated for a (3+1) dimensional theory in the leading WKB approximation in the thin-wall limit. It is found that the induced nucleation rate of bubbles, capable of expansion, is exponentially small at any energy. The negative exponential power in the rate reaches its maximum...
متن کاملNumerical Study of Induced False Vacuum Decay at High Energies
We calculate numerically the probability exp[ λF (E/Esph, N/Nsph)] of the false vacuum decay in the massive four-dimensional−λφ4 model from multiparticle initial states with fixed number of particles N and energy E greater than the height of the barrier Esph. We find that at E ∼< 3Esph and N ∼< 0.4Nsph the decay is classically forbidden and thus is exponentially suppressed. We argue that the cl...

We calculate numerically the probability exp[ 1 λ F (E/E sph , N/N sph)] of the false vacuum decay in the massive four-dimensional −λφ 4 model from multipar-ticle initial states with fixed number of particles N and energy E greater than the height of the barrier E sph. We find that at E ∼ < 3E sph and N ∼ < 0.4N sph the decay is classically forbidden and thus is exponentially suppressed. We arg...
