Fate of False Vacuum in Non-perturbative Regimes

  title={Fate of False Vacuum in Non-perturbative Regimes},
  author={Marco Frasca and Anish Ghoshal and Nobuchika Okada},
A formalism to describe the false-vacuum decay in non-perturbative regimes was proposed re-cently. Here, we extend it to the presence of Einstein gravity and calculate the corresponding effective potential and decay rate for a λφ 4 scalar field theory. A comparison with the usual perturbative decay rate shows that the higher the coupling λ , the greater the decay probability. From the running of the self-interaction coupling, we conclude that the theory becomes weakly coupled in the infrared…

Fate of the false vacuum in string-inspired nonlocal field theory

In this article, we study Coleman bounce in weakly nonlocal theories which are motivated from string field theory. The kinetic term is extended via an infinite series of high-order derivatives, which



The Fate of the False Vacuum. 1. Semiclassical Theory

It is possible for a classical field theory to have two homogeneous stable equilibrium states with different energy densities. In the quantum version of the theory, the state of higher energy density

A new approach to vacuum decay in quantum field theory, based on a simple variational formulation in field space using a tunneling potential, is ideally suited to study the effects of gravity on such

Exactly solvable vacuum decays with gravity

Using a new approach to the analysis of false vacuum decay based on the so-called tunneling potential, we develop a general method to find scalar potentials with a false vacuum with exactly solvable

A tunneling bounce driving the decay of a metastable vacuum must respect an integral constraint dictated by simple scaling arguments that is very useful to determine key properties of the bounce.

Gravitational Effects on and of Vacuum Decay

It is possible for a classical field theory to have two stable homogeneous ground states, only one of which is an absolute energy minimum. In the quantum version of the theory, the ground state of

Vacuum decay and quadratic gravity: the massive case

False vacuum decay in field theory may be formulated as a boundary value problem in Euclidean space. In a previous work, we studied its solution in single scalar field theories with quadratic gravity

Scalar field theory in the strong self-interaction limit

The Standard Model with a classical conformal invariance holds the promise to lead to a better understanding of the hierarchy problem and could pave the way beyond the Standard Model physics. Thus,

Quintessence Dark Energy from strongly-coupled Higgs mass gap: Local and Non-local higher-derivative non-perturbative scenarios

We entertain the possibility that dark energy arises from the Higgs field of quintessence type in the non-perturbative regimes. For this purpose we utilize a set of exact solutions of Higgs field

Abstract.We provide the solution of the classical theory for the Higgs sector of the Standard Model obtaining the exact Green’s function for the broken phase. Solving the Dyson-Schwinger equations
