Hawking-Moss Tunneling with a Dirac-Born-Infeld Action

Understand

The Hawking-Moss tunneling rate for a field described by the Dirac-Born-Infeld action is calculated using a stochastic approach.

• We find that the effect of the non-trivial kinetic term is to enhance the tunneling rate, which can be exponentially significant.
• This result should be compared to the DBI enhancement found in the Coleman-de Luccia case.
