Generalised escape paths for dynamical tunneling in QFT
Luc Darmé, Joerg Jaeckel, Marek Lewicki
We present a formalism based on the functional Schrödinger equation to analyse time-dependent tunneling in quantum field theory at the semi-classical level. The full problem is red…
Testing String Vacua in the Lab: From a Hidden CMB to Dark Forces in Flux Compactifications
Michele Cicoli, Mark Goodsell, Joerg Jaeckel +1
We perform a detailed analysis of the phenomenological properties of hidden Abelian gauge bosons with a kinetic mixing with the ordinary photon within type IIB flux compactificatio…
Why the early Universe preferred the non-supersymmetric vacuum: Part II
Steven A. Abel, Joerg Jaeckel, Valentin V. Khoze
It was recently shown in hep-th/0610334 that in the context of the ISS models with a metastable supersymmetry breaking vacuum, thermal effects generically drive the Universe to the…
SUSY breaking by a metastable ground state: Why the early Universe preferred the non-supersymmetric vacuum
Steven A. Abel, Chong-Sun Chu, Joerg Jaeckel +1
Supersymmetry breaking in a metastable vacuum is re-examined in a cosmological context. It is shown that thermal effects generically drive the Universe to the metastable minimum ev…
